/**
* Trait that provides a domain specific language (DSL) for expressing assertions in tests
* using the word must.
*
*
* For example, if you mix Matchers into
* a suite class, you can write an equality assertion in that suite like this:
*
*
*
* result must equal (3)
*
*
*
* Here result is a variable, and can be of any type. If the object is an
* Int with the value 3, execution will continue (i.e., the expression will result
* in the unit value, ()). Otherwise, a TestFailedException
* will be thrown with a detail message that explains the problem, such as "7 did not equal 3".
* This TestFailedException will cause the test to fail.
*

*
* Matchers migration in ScalaTest 2.0 and 2.1.0
*
* Deprecations
*
*
* Prior to 2.0, ScalaTest's matchers DSL was provided by traits
* org.scalatest.matchers.ShouldMatchers and
* org.scalatest.matchers.MustMatchers. These are now deprecated in favor of
* traits in package org.scalatest. The fully qualified name of the original
* ShouldMatchers is now org.scalatest.Matchers, and the fully qualified
* name of the original MustMatchers is now org.scalatest.MustMatchers.
* The old fully qualified names will continue to work during a lengthy deprecation cycle, but
* will generate a deprecation warning and eventually be removed in a future version
* of ScalaTest. You can migrate existing uses of ShouldMatchers by simply importing
* or mixing in org.scalatest.Matchers instead of
* org.scalatest.matchers.ShouldMatchers, and can migrate existing
* uses of org.scalatest.matchers.MustMatchers by importing or
* mixing in org.scalatest.MustMatchers instead of org.scalatest.matchers.MustMatchers.
*
*
*
* Two other deprecations in ScalaTest 2.0 matchers are be === <value> and evaluating ...
* must produce syntax. This will both continue to work as before, but will generate a deprecation
* warning and eventually be removed in a future version of ScalaTest. the be === syntax is being deprecated so that all uses
* of === in ScalaTest consistently provide the new
* features of tunable type checking, tolerance support, and customized equality. Please replace uses of this syntax with one of the other
* ways to check equality described in the next section. The eventually syntax is being deprecated because it is replaced by thrownBy
* clauses, as described below.
*
*
* Potential breakages
*
*
* Although ScalaTest's matchers have undergone a major refactor in 2.0, all previously documented syntax for matchers must continue to work exactly
* the same with one potential exception, which must in practice be extremely rare. The potential breakage is that if you included length or size
* along with custom have-property matchers that you wrote, you'll get a compiler error. To fix such an error, add after
* your length or size invocation an (of [<type>]) clause, as
* described below.
*
*
*
* The only other source of potential breakage is the fragile base class problem. We have added fields and methods to Matchers in 2.0 that may
* conflict with fields and methods in your existing classes and cause a compiler error. Such issues can usually be easily fixed locally with simple renames or refactors,
* but if you prefer to subtract a token from Matchers, you can do so by mixing together your own Matchers trait
* from component traits, as described below. Note that you must not see any new implicit conflicts, because we managed to reduce the number
* of implicits brought into scope by 2.0 matchers compared to 1.x by about 75%.
*
*
*
* Checking equality with matchers
*
*
* ScalaTest matchers provides five different ways to check equality, each designed to address a different need. They are:
*
*
*
* result must equal (3) // can customize equality
* result must === (3) // can customize equality and enforce type constraints
* result must be (3) // cannot customize equality, so fastest to compile
* result mustEqual 3 // can customize equality, no parentheses required
* result mustBe 3 // cannot customize equality, so fastest to compile, no parentheses required
*
*
*
* The “left must equal (right)” syntax requires an
* org.scalautils.Equality[L] to be provided (either implicitly or explicitly), where
* L is the left-hand type on which must is invoked. In the "left must equal (right)" case,
* for example, L is the type of left. Thus if left is type Int, the "left must
* equal (right)"
* statement would require an Equality[Int].
*
*
*
* By default, an implicit Equality[T] instance is available for any type T, in which equality is implemented
* by simply invoking == on the left
* value, passing in the right value, with special treatment for arrays. If either left or right is an array, deep
* will be invoked on it before comparing with ==. Thus, the following expression
* will yield false, because Array's equals method compares object identity:
*
*
*
* Array(1, 2) == Array(1, 2) // yields false
*
*
*
* The next expression will by default not result in a TestFailedException, because default Equality[Array[Int]] compares
* the two arrays structurally, taking into consideration the equality of the array's contents:
*
*
*
* Array(1, 2) must equal (Array(1, 2)) // succeeds (i.e., does not throw TestFailedException)
*
*
*
* If you ever do want to verify that two arrays are actually the same object (have the same identity), you can use the
* be theSameInstanceAs syntax, described below.
*
*
*
* You can customize the meaning of equality for a type when using "must equal," "must ===,"
* or mustEqual syntax by defining implicit Equality instances that will be used instead of default Equality.
* You might do this to normalize types before comparing them with ==, for instance, or to avoid calling the == method entirely,
* such as if you want to compare Doubles with a tolerance.
* For an example, see the main documentation of trait Equality.
*
*
*
* You can always supply implicit parameters explicitly, but in the case of implicit parameters of type Equality[T], ScalaUtils provides a
* simple "explictly" DSL. For example, here's how you could explicitly supply an Equality[String] instance that normalizes both left and right
* sides (which must be strings), by transforming them to lowercase:
*
*
*
* scala> import org.scalatest.MustMatchers._
* import org.scalatest.MustMatchers._
*
* scala> import org.scalautils.Explicitly._
* import org.scalautils.Explicitly._
*
* scala> import org.scalautils.StringNormalizations._
* import org.scalautils.StringNormalizations._
*
* scala> "Hi" must equal ("hi") (after being lowerCased)
*
*
*
* The after being lowerCased expression results in an Equality[String], which is then passed
* explicitly as the second curried parameter to equal. For more information on the explictly DSL, see the main documentation
* for trait Explicitly.
*
*
*
* The "must be" and mustBe syntax do not take an Equality[T] and can therefore not be customized.
* They always use the default approach to equality described above. As a result, "must be" and mustBe will
* likely be the fastest-compiling matcher syntax for equality comparisons, since the compiler need not search for
* an implicit Equality[T] each time.
*
*
*
* The must === syntax (and its complement, must !==) can be used to enforce type
* constraints at compile-time between the left and right sides of the equality comparison. Here's an example:
*
*
*
* scala> import org.scalatest.MustMatchers._
* import org.scalatest.MustMatchers._
*
* scala> import org.scalautils.TypeCheckedTripleEquals._
* import org.scalautils.TypeCheckedTripleEquals._
*
* scala> Some(2) must === (2)
* <console>:17: error: types Some[Int] and Int do not adhere to the equality constraint
* selected for the === and !== operators; the missing implicit parameter is of
* type org.scalautils.Constraint[Some[Int],Int]
* Some(2) must === (2)
* ^
*
*
*
* By default, the "Some(2) must === (2)" statement would fail at runtime. By mixing in
* the equality constraints provided by TypeCheckedTripleEquals, however, the statement fails to compile. For more information
* and examples, see the main documentation for trait TypeCheckedTripleEquals.
*
*
*
* Checking size and length
*
*
* You can check the size or length of any type of object for which it
* makes sense. Here's how checking for length looks:
*
*
* result must have length 3
*
*
*
* Size is similar:
*
*
*
* result must have size 10
*
*
*
* The length syntax can be used with String, Array, any scala.collection.GenSeq,
* any java.util.List, and any type T for which an implicit Length[T] type class is
* available in scope.
* Similarly, the size syntax can be used with Array, any scala.collection.GenTraversable,
* any java.util.Collection, any java.util.Map, and any type T for which an implicit Size[T] type class is
* available in scope. You can enable the length or size syntax for your own arbitrary types, therefore,
* by defining Length or Size type
* classes for those types.
*
*
*
* In addition, the length syntax can be used with any object that has a field or method named length
* or a method named getLength. Similarly, the size syntax can be used with any
* object that has a field or method named size or a method named getSize.
* The type of a length or size field, or return type of a method, must be either Int
* or Long. Any such method must take no parameters. (The Scala compiler will ensure at compile time that
* the object on which must is being invoked has the appropriate structure.)
*
*
*
* Checking strings
*
*
* You can check for whether a string starts with, ends with, or includes a substring like this:
*
*
*
* string must startWith ("Hello")
* string must endWith ("world")
* string must include ("seven")
*
*
*
* You can check for whether a string starts with, ends with, or includes a regular expression, like this:
*
*
*
* string must startWith regex "Hel*o"
* string must endWith regex "wo.ld"
* string must include regex "wo.ld"
*
*
*
* And you can check whether a string fully matches a regular expression, like this:
*
*
*
* string must fullyMatch regex """(-)?(\d+)(\.\d*)?"""
*
*
*
* The regular expression passed following the regex token can be either a String
* or a scala.util.matching.Regex.
*
*
*
* With the startWith, endWith, include, and fullyMatch
* tokens can also be used with an optional specification of required groups, like this:
*
*
*
* "abbccxxx" must startWith regex ("a(b*)(c*)" withGroups ("bb", "cc"))
* "xxxabbcc" must endWith regex ("a(b*)(c*)" withGroups ("bb", "cc"))
* "xxxabbccxxx" must include regex ("a(b*)(c*)" withGroups ("bb", "cc"))
* "abbcc" must fullyMatch regex ("a(b*)(c*)" withGroups ("bb", "cc"))
*
*
*
* You can check whether a string is empty with empty:
*
*
*
* s mustBe empty
*
*
*
* You can also use most of ScalaTest's matcher syntax for collections on String by
* treating the Strings as collections of characters. For examples, see the
* Strings and Arrays as collections section below.
*
*
*
* Greater and less than
*
*
* You can check whether any type for which an implicit Ordering[T] is available
* is greater than, less than, greater than or equal, or less
* than or equal to a value of type T. The syntax is:
*
*
* one must be < 7
* one must be > 0
* one must be <= 7
* one must be >= 0
*
*
*
* Checking Boolean properties with be
*
*
* If an object has a method that takes no parameters and returns boolean, you can check
* it by placing a Symbol (after be) that specifies the name
* of the method (excluding an optional prefix of "is"). A symbol literal
* in Scala begins with a tick mark and ends at the first non-identifier character. Thus,
* 'traversableAgain results in a Symbol object at runtime, as does
* 'completed and 'file. Here's an example:
*
*
*
* iter mustBe 'traversableAgain
*
*
* Given this code, ScalaTest will use reflection to look on the object referenced from
* emptySet for a method that takes no parameters and results in Boolean,
* with either the name empty or isEmpty. If found, it will invoke
* that method. If the method returns true, execution will continue. But if it returns
* false, a TestFailedException will be thrown that will contain a detail message, such as:
*
*
* non-empty iterator was not traversableAgain
*
*
*
* This be syntax can be used with any reference (AnyRef) type. If the object does
* not have an appropriately named predicate method, you'll get a TestFailedException
* at runtime with a detailed message that explains the problem.
* (For the details on how a field or method is selected during this
* process, see the documentation for BeWord.)
*
*
*
* If you think it reads better, you can optionally put a or an after
* be. For example, java.io.File has two predicate methods,
* isFile and isDirectory. Thus with a File object
* named temp, you could write:
*
*
*
* temp must be a 'file
*
*
*
* Or, given java.awt.event.KeyEvent has a method isActionKey that takes
* no arguments and returns Boolean, you could assert that a KeyEvent is
* an action key with:
*
*
*
* keyEvent must be an 'actionKey
*
*
*
* If you prefer to check Boolean properties in a type-safe manner, you can use a BePropertyMatcher.
* This would allow you to write expressions such as:
*
*
*
* xs mustBe traversableAgain
* temp must be a file
* keyEvent must be an actionKey
*
*
*
* These expressions would fail to compile if must is used on an inappropriate type, as determined
* by the type parameter of the BePropertyMatcher being used. (For example, file in this example
* would likely be of type BePropertyMatcher[java.io.File]. If used with an appropriate type, such an expression will compile
* and at run time the Boolean property method or field will be accessed directly; i.e., no reflection will be used.
* See the documentation for BePropertyMatcher for more information.
*
*
*
* Using custom BeMatchers
*
* If you want to create a new way of using be, which doesn't map to an actual property on the
* type you care about, you can create a BeMatcher. You could use this, for example, to create BeMatcher[Int]
* called odd, which would match any odd Int, and even, which would match
* any even Int.
* Given this pair of BeMatchers, you could check whether an Int was odd or even with expressions like:
*
*
*
* num mustBe odd
* num must not be even
*
*
* For more information, see the documentation for BeMatcher.
*
*
* Checking object identity
*
*
* If you need to check that two references refer to the exact same object, you can write:
*
*
*
* ref1 must be theSameInstanceAs ref2
*
*
*
* Checking an object's class
*
*
* If you need to check that an object is an instance of a particular class or trait, you can supply the type to
* “be a” or “be an”:
*
*
*
* result1 mustBe a [Tiger]
* result1 must not be an [Orangutan]
*
*
*
* Because type parameters are erased on the JVM, we recommend you insert an underscore for any type parameters
* when using this syntax. Both of the following test only that the result is an instance of List[_], because at
* runtime the type parameter has been erased:
*
*
*
* result mustBe a [List[_]] // recommended
* result mustBe a [List[Fruit]] // discouraged
*
*
*
* Checking numbers against a range
*
*
* Often you may want to check whether a number is within a
* range. You can do that using the +- operator, like this:
*
*
*
* sevenDotOh must equal (6.9 +- 0.2)
* sevenDotOh must === (6.9 +- 0.2)
* sevenDotOh must be (6.9 +- 0.2)
* sevenDotOh mustEqual 6.9 +- 0.2
* sevenDotOh mustBe 6.9 +- 0.2
*
*
*
* Any of these expressions will cause a TestFailedException to be thrown if the floating point
* value, sevenDotOh is outside the range 6.7 to 7.1.
* You can use +- with any type T for which an implicit Numeric[T] exists, such as integral types:
*
*
*
* seven must equal (6 +- 2)
* seven must === (6 +- 2)
* seven must be (6 +- 2)
* seven mustEqual 6 +- 2
* seven mustBe 6 +- 2
*
*
*
* Checking for emptiness
*
*
* You can check whether an object is "empty", like this:
*
*
*
* traversable mustBe empty
* javaMap must not be empty
*
*
*
* The empty token can be used with any type L for which an implicit Emptiness[L] exists.
* The Emptiness companion object provides implicits for GenTraversable[E], java.util.Collection[E],
* java.util.Map[K, V], String, Array[E], and Option[E]. In addition, the
* Emptiness companion object provides structural implicits for types that declare an isEmpty method that
* returns a Boolean. Here are some examples:
*
*
*
* scala> import org.scalatest.MustMatchers._
* import org.scalatest.MustMatchers._
*
* scala> List.empty mustBe empty
*
* scala> None mustBe empty
*
* scala> Some(1) must not be empty
*
* scala> "" mustBe empty
*
* scala> new java.util.HashMap[Int, Int] mustBe empty
*
* scala> new { def isEmpty = true} mustBe empty
*
* scala> Array(1, 2, 3) must not be empty
*
*
*
* Working with "containers"
*
*
* You can check whether a collection contains a particular element like this:
*
*
*
* traversable must contain ("five")
*
*
*
* The contain syntax shown above can be used with any type C that has a "containing" nature, evidenced by
* an implicit org.scalatest.enablers.Containing[L], where L is left-hand type on
* which must is invoked. In the Containing
* companion object, implicits are provided for types GenTraversable[E], java.util.Collection[E],
* java.util.Map[K, V], String, Array[E], and Option[E].
* Here are some examples:
*
*
*
* scala> import org.scalatest.MustMatchers._
* import org.scalatest.MustMatchers._
*
* scala> List(1, 2, 3) must contain (2)
*
* scala> Map('a' -> 1, 'b' -> 2, 'c' -> 3) must contain ('b' -> 2)
*
* scala> Set(1, 2, 3) must contain (2)
*
* scala> Array(1, 2, 3) must contain (2)
*
* scala> "123" must contain ('2')
*
* scala> Some(2) must contain (2)
*
*
*
* ScalaTest's implicit methods that provide the Containing[L] type classes require an Equality[E], where
* E is an element type. For example, to obtain a Containing[Array[Int]] you must supply an Equality[Int],
* either implicitly or explicitly. The contain syntax uses this Equality[E] to determine containership.
* Thus if you want to change how containership is determined for an element type E, place an implicit Equality[E]
* in scope or use the explicitly DSL. Although the implicit parameter required for the contain syntax is of type Containing[L],
* implicit conversions are provided in the Containing companion object from Equality[E] to the various
* types of containers of E. Here's an example:
*
*
*
* scala> import org.scalatest.MustMatchers._
* import org.scalatest.MustMatchers._
*
* scala> List("Hi", "Di", "Ho") must contain ("ho")
* org.scalatest.exceptions.TestFailedException: List(Hi, Di, Ho) did not contain element "ho"
* at ...
*
* scala> import org.scalautils.Explicitly._
* import org.scalautils.Explicitly._
*
* scala> import org.scalautils.StringNormalizations._
* import org.scalautils.StringNormalizations._
*
* scala> (List("Hi", "Di", "Ho") must contain ("ho")) (after being lowerCased)
*
*
*
* Note that when you use the explicitly DSL with contain you need to wrap the entire
* contain expression in parentheses, as shown here.
*
*
*
* (List("Hi", "Di", "Ho") must contain ("ho")) (after being lowerCased)
* ^ ^
*
*
*
* In addition to determining whether an object contains another object, you can use contain to
* make other determinations.
* For example, the contain oneOf syntax ensures that one and only one of the specified elements are
* contained in the containing object:
*
*
*
* List(1, 2, 3, 4, 5) must contain oneOf (5, 7, 9)
* Some(7) must contain oneOf (5, 7, 9)
* "howdy" must contain oneOf ('a', 'b', 'c', 'd')
*
*
*
* Note that if multiple specified elements appear in the containing object, oneOf will fail:
*
*
*
* scala> List(1, 2, 3) must contain oneOf (2, 3, 4)
* org.scalatest.exceptions.TestFailedException: List(1, 2, 3) did not contain one of (2, 3, 4)
* at ...
*
*
*
* If you really want to ensure one or more of the specified elements are contained in the containing object,
* use atLeastOneOf, described below, instead of oneOf. Keep in mind, oneOf
* means "exactly one of."
*
*
*
* Note also that with any contain syntax, you can place custom implicit Equality[E] instances in scope
* to customize how containership is determined, or use the explicitly DSL. Here's an example:
*
*
*
* (Array("Doe", "Ray", "Me") must contain oneOf ("X", "RAY", "BEAM")) (after being lowerCased)
*
*
*
* The contain noneOf syntax does the opposite of oneOf: it ensures none of the specified elements
* are contained in the containing object:
*
*
*
* List(1, 2, 3, 4, 5) must contain noneOf (7, 8, 9)
* Some(0) must contain noneOf (7, 8, 9)
* "12345" must contain noneOf ('7', '8', '9')
*
*
*
* Working with "aggregations"
*
*
* As mentioned, the "contain," "contain oneOf," and "contain noneOf" syntax requires a
* Containing[L] be provided, where L is the left-hand type. Other contain syntax, which
* will be described in this section, requires an Aggregating[L] be provided, where again L is the left-hand type.
* (An Aggregating[L] instance defines the "aggregating nature" of a type L.)
* The reason, essentially, is that contain syntax that makes sense for Option is enabled by
* Containing[L], whereas syntax that does not make sense for Option is enabled
* by Aggregating[L]. For example, it doesn't make sense to assert that an Option[Int] contains all of a set of integers, as it
* could only ever contain one of them. But this does make sense for a type such as List[Int] that can aggregate zero to many integers.
*
*
*
* The Aggregating companion object provides implicit instances of Aggregating[L]
* for types GenTraversable[E], java.util.Collection[E],
* java.util.Map[K, V], String, Array[E]. Note that these are the same types as are supported with
* Containing, but with Option[E] missing.
* Here are some examples:
*
*
*
* The contain atLeastOneOf syntax, for example, works for any type L for which an Aggregating[L] exists. It ensures
* that at least one of (i.e., one or more of) the specified objects are contained in the containing object:
*
*
*
* List(1, 2, 3) must contain atLeastOneOf (2, 3, 4)
* Array(1, 2, 3) must contain atLeastOneOf (3, 4, 5)
* "abc" must contain atLeastOneOf ('c', 'a', 't')
*
*
*
* Similar to Containing[L], the implicit methods that provide the Aggregating[L] instances require an Equality[E], where
* E is an element type. For example, to obtain a Aggregating[Vector[String]] you must supply an Equality[String],
* either implicitly or explicitly. The contain syntax uses this Equality[E] to determine containership.
* Thus if you want to change how containership is determined for an element type E, place an implicit Equality[E]
* in scope or use the explicitly DSL. Although the implicit parameter required for the contain syntax is of type Aggregating[L],
* implicit conversions are provided in the Aggregating companion object from Equality[E] to the various
* types of aggregations of E. Here's an example:
*
*
*
* (Vector(" A", "B ") must contain atLeastOneOf ("a ", "b", "c")) (after being lowerCased and trimmed)
*
*
*
* The "contain atMostOneOf" syntax lets you specify a set of objects at most one of which must be contained in the containing object:
*
*
*
* List(1, 2, 3, 4, 5) must contain atMostOneOf (5, 6, 7)
*
*
*
* The "contain allOf" syntax lets you specify a set of objects that must all be contained in the containing object:
*
*
*
* List(1, 2, 3, 4, 5) must contain allOf (2, 3, 5)
*
*
*
* The "contain only" syntax lets you assert that the containing object contains only the specified objects, though it may
* contain more than one of each:
*
*
*
* List(1, 2, 3, 2, 1) must contain only (1, 2, 3)
*
*
*
* The "contain theSameElementsAs" and "contain theSameElementsInOrderAs syntax differ from the others
* in that the right hand side is a GenTraversable[_] rather than a varargs of Any. (Note: in a future 2.0 milestone release, possibly
* 2.0.M6, these will likely be widened to accept any type R for which an Aggregating[R] exists.)
*
*
*
* The "contain theSameElementsAs" syntax lets you assert that two aggregations contain the same objects:
*
*
*
* List(1, 2, 2, 3, 3, 3) must contain theSameElementsAs Vector(3, 2, 3, 1, 2, 3)
*
*
*
* The number of times any family of equal objects appears must also be the same in both the left and right aggregations.
* The specified objects may appear multiple times, but must appear in the order they appear in the right-hand list. For example, if
* the last 3 element is left out of the right-hand list in the previous example, the expression would fail because the left side
* has three 3's and the right hand side has only two:
*
*
*
* List(1, 2, 2, 3, 3, 3) must contain theSameElementsAs Vector(3, 2, 3, 1, 2)
* org.scalatest.exceptions.TestFailedException: List(1, 2, 2, 3, 3, 3) did not contain the same elements as Vector(3, 2, 3, 1, 2)
* at ...
*
*
*
* Working with "sequences"
*
*
* The rest of the contain syntax, which
* will be described in this section, requires a Sequencing[L] be provided, where again L is the left-hand type.
* (A Sequencing[L] instance defines the "sequencing nature" of a type L.)
* The reason, essentially, is that contain syntax that implies an "order" of elements makes sense only for types that place elements in a sequence.
* For example, it doesn't make sense to assert that a Map[String, Int] or Set[Int] contains all of a set of integers in a particular
* order, as these types don't necessarily define an order for their elements. But this does make sense for a type such as Seq[Int] that does define
* an order for its elements.
*
*
*
* The Sequencing companion object provides implicit instances of Sequencing[L]
* for types GenSeq[E], java.util.List[E],
* String, and Array[E].
* Here are some examples:
*
*
*
* Similar to Containing[L], the implicit methods that provide the Aggregating[L] instances require an Equality[E], where
* E is an element type. For example, to obtain a Aggregating[Vector[String]] you must supply an Equality[String],
* either implicitly or explicitly. The contain syntax uses this Equality[E] to determine containership.
* Thus if you want to change how containership is determined for an element type E, place an implicit Equality[E]
* in scope or use the explicitly DSL. Although the implicit parameter required for the contain syntax is of type Aggregating[L],
* implicit conversions are provided in the Aggregating companion object from Equality[E] to the various
* types of aggregations of E. Here's an example:
*
*
*
* The "contain inOrderOnly" syntax lets you assert that the containing object contains only the specified objects, in order.
* The specified objects may appear multiple times, but must appear in the order they appear in the right-hand list. Here's an example:
*
*
*
* List(1, 2, 2, 3, 3, 3) must contain inOrderOnly (1, 2, 3)
*
*
*
* The "contain inOrder" syntax lets you assert that the containing object contains only the specified objects in order, like
* inOrderOnly, but allows other objects to appear in the left-hand aggregation as well:
* contain more than one of each:
*
*
*
* List(0, 1, 2, 2, 99, 3, 3, 3, 5) must contain inOrder (1, 2, 3)
*
*
*
* Note that "order" in inOrder, inOrderOnly, and theSameElementsInOrderAs (described below)
* in the Aggregation[L] instances built-in to ScalaTest is defined as "iteration order".
*
*
*
* Lastly, the "contain theSameElementsInOrderAs" syntax lets you assert that two aggregations contain
* the same exact elements in the same (iteration) order:
*
*
*
* List(1, 2, 3) must contain theSameElementsInOrderAs collection.mutable.TreeSet(3, 2, 1)
*
*
*
* The previous assertion succeeds because the iteration order of aTreeSet is the natural
* ordering of its elements, which in this case is 1, 2, 3. An iterator obtained from the left-hand List will produce the same elements
* in the same order.
*
*
*
* Working with "sortables"
*
*
* You can also ask whether the elements of "sortable" objects (such as Arrays, Java Lists, and GenSeqs)
* are in sorted order, like this:
*
*
*
* List(1, 2, 3) mustBe sorted
*
*
*
* Working with iterators
*
*
* Althought it seems desireable to provide similar matcher syntax for Scala and Java iterators to that provided for sequences like
* Seqs, Array, and java.util.List, the
* ephemeral nature of iterators makes this problematic. Some syntax (such as must contain) is relatively straightforward to
* support on iterators, but other syntax (such
* as, for example, Inspector expressions on nested iterators) is not. Rather
* than allowing inconsistencies between sequences and iterators in the API, we chose to not support any such syntax directly on iterators:
*
*
* scala> val it = List(1, 2, 3).iterator
* it: Iterator[Int] = non-empty iterator
*
* scala> it must contain (2)
* <console>:15: error: could not find implicit value for parameter typeClass1: org.scalatest.enablers.Containing[Iterator[Int]]
* it must contain (2)
* ^
*
*
*
* Instead, you will need to convert your iterators to a sequence explicitly before using them in matcher expressions:
*
*
*
* scala> it.toStream must contain (2)
*
*
*
* We recommend you convert (Scala or Java) iterators to Streams, as shown in the previous example, so that you can
* continue to reap any potential benefits provided by the laziness of the underlying iterator.
*
*
*
* Inspector shorthands
*
*
* You can use the Inspectors syntax with matchers as well as assertions. If you have a multi-dimensional collection, such as a
* list of lists, using Inspectors is your best option:
*
*
*
* val yss =
* List(
* List(1, 2, 3),
* List(1, 2, 3),
* List(1, 2, 3)
* )
*
* forAll (yss) { ys =>
* forAll (ys) { y => y must be > 0 }
* }
*
*
*
* For assertions on one-dimensional collections, however, matchers provides "inspector shorthands." Instead of writing:
*
*
*
* val xs = List(1, 2, 3)
* forAll (xs) { x => x must be < 10 }
*
*
*
* You can write:
*
*
*
* all (xs) must be < 10
*
*
*
* The previous statement asserts that all elements of the xs list must be less than 10.
* All of the inspectors have shorthands in matchers. Here is the full list:
*
*
*
* all - succeeds if the assertion holds true for every elementatLeast - succeeds if the assertion holds true for at least the specified number of elementsatMost - succeeds if the assertion holds true for at most the specified number of elementsbetween - succeeds if the assertion holds true for between the specified minimum and maximum number of elements, inclusiveevery - same as all, but lists all failing elements if it fails (whereas all just reports the first failing element)exactly - succeeds if the assertion holds true for exactly the specified number of elements
*
*
* Here are some examples:
*
*
*
* scala> import org.scalatest.MustMatchers._
* import org.scalatest.MustMatchers._
*
* scala> val xs = List(1, 2, 3, 4, 5)
* xs: List[Int] = List(1, 2, 3, 4, 5)
*
* scala> all (xs) must be > 0
*
* scala> atMost (2, xs) must be >= 4
*
* scala> atLeast (3, xs) must be < 5
*
* scala> between (2, 3, xs) must (be > 1 and be < 5)
*
* scala> exactly (2, xs) must be <= 2
*
* scala> every (xs) must be < 10
*
* scala> // And one that fails...
*
* scala> exactly (2, xs) mustEqual 2
* org.scalatest.exceptions.TestFailedException: 'exactly(2)' inspection failed, because only 1 element
* satisfied the assertion block at index 1:
* at index 0, 1 did not equal 2,
* at index 2, 3 did not equal 2,
* at index 3, 4 did not equal 2,
* at index 4, 5 did not equal 2
* in List(1, 2, 3, 4, 5)
* at ...
*
*
*
* Like Inspectors, objects used with inspector shorthands can be any type T for which a Collecting[T, E]
* is availabe, which by default includes GenTraversable,
* Java Collection, Java Map, Arrays, and Strings.
* Here are some examples:
*
*
*
* scala> import org.scalatest._
* import org.scalatest._
*
* scala> import MustMatchers._
* import MustMatchers._
*
* scala> all (Array(1, 2, 3)) must be < 5
*
* scala> import collection.JavaConverters._
* import collection.JavaConverters._
*
* scala> val js = List(1, 2, 3).asJava
* js: java.util.List[Int] = [1, 2, 3]
*
* scala> all (js) must be < 5
*
* scala> val jmap = Map("a" -> 1, "b" -> 2).asJava
* jmap: java.util.Map[String,Int] = {a=1, b=2}
*
* scala> atLeast(1, jmap) mustBe Entry("b", 2)
*
* scala> atLeast(2, "hello, world!") mustBe 'o'
*
*
*
* Single-element collections
*
*
* To assert both that a collection contains just one "lone" element as well as something else about that element, you can use
* the loneElement syntax provided by trait LoneElement. For example, if a
* Set[Int] must contain just one element, an Int
* less than or equal to 10, you could write:
*
*
*
* import LoneElement._
* set.loneElement must be <= 10
*
*
*
* You can invoke loneElement on any type T for which an implicit Collecting[E, T]
* is available, where E is the element type returned by the loneElement invocation. By default, you can use loneElement
* on GenTraversable, Java Collection, Java Map, Array, and String.
*
*
*
* Java collections and maps
*
*
* You can use similar syntax on Java collections (java.util.Collection) and maps (java.util.Map).
* For example, you can check whether a Java Collection or Map is empty,
* like this:
*
*
*
* javaCollection must be ('empty)
* javaMap must be ('empty)
*
*
*
* Even though Java's List type doesn't actually have a length or getLength method,
* you can nevertheless check the length of a Java List (java.util.List) like this:
*
*
*
* javaList must have length 9
*
*
*
* You can check the size of any Java Collection or Map, like this:
*
*
*
* javaMap must have size 20
* javaSet must have size 90
*
*
*
* In addition, you can check whether a Java Collection contains a particular
* element, like this:
*
*
*
* javaCollection must contain ("five")
*
*
*
* One difference to note between the syntax supported on Java and Scala collections is that
* in Java, Map is not a subtype of Collection, and does not
* actually define an element type. You can ask a Java Map for an "entry set"
* via the entrySet method, which will return the Map's key/value pairs
* wrapped in a set of java.util.Map.Entry, but a Map is not actually
* a collection of Entry. To make Java Maps easier to work with, however,
* ScalaTest matchers allows you to treat a Java Map as a collection of Entry,
* and defines a convenience implementation of java.util.Map.Entry in
* org.scalatest.Entry. Here's how you use it:
*
*
*
* javaMap must contain (Entry(2, 3))
* javaMap must contain oneOf (Entry(2, 3), Entry(3, 4))
*
*
* You can you alse just check whether a Java Map contains a particular key, or value, like this:
*
*
* javaMap must contain key 1
* javaMap must contain value "Howdy"
*
*
*
* Strings and Arrays as collections
*
*
* You can also use all the syntax described above for Scala and Java collections on Arrays and
* Strings. Here are some examples:
*
*
*
* scala> import org.scalatest._
* import org.scalatest._
*
* scala> import MustMatchers._
* import MustMatchers._
*
* scala> atLeast (2, Array(1, 2, 3)) must be > 1
*
* scala> atMost (2, "halloo") mustBe 'o'
*
* scala> Array(1, 2, 3) mustBe sorted
*
* scala> "abcdefg" mustBe sorted
*
* scala> Array(1, 2, 3) must contain atMostOneOf (3, 4, 5)
*
* scala> "abc" must contain atMostOneOf ('c', 'd', 'e')
*
*
*
* be as an equality comparison
*
*
* All uses of be other than those shown previously perform an equality comparison. They work
* the same as equal when it is used with default equality. This redundancy between be and equals exists in part
* because it enables syntax that sometimes sounds more natural. For example, instead of writing:
*
*
*
* result must equal (null)
*
*
*
* You can write:
*
*
*
* result must be (null)
*
*
*
* (Hopefully you won't write that too much given null is error prone, and Option
* is usually a better, well, option.)
* As mentioned previously, the other difference between equal
* and be is that equal delegates the equality check to an Equality typeclass, whereas
* be always uses default equality.
* Here are some other examples of be used for equality comparison:
*
*
*
* sum must be (7.0)
* boring must be (false)
* fun must be (true)
* list must be (Nil)
* option must be (None)
* option must be (Some(1))
*
*
*
* As with equal used with default equality, using be on arrays results in deep being called on both arrays prior to
* calling equal. As a result,
* the following expression would not throw a TestFailedException:
*
*
*
* Array(1, 2) must be (Array(1, 2)) // succeeds (i.e., does not throw TestFailedException)
*
*
*
* Because be is used in several ways in ScalaTest matcher syntax, just as it is used in many ways in English, one
* potential point of confusion in the event of a failure is determining whether be was being used as an equality comparison or
* in some other way, such as a property assertion. To make it more obvious when be is being used for equality, the failure
* messages generated for those equality checks will include the word equal in them. For example, if this expression fails with a
* TestFailedException:
*
*
*
* option must be (Some(1))
*
*
*
* The detail message in that TestFailedException will include the words "equal to" to signify be
* was in this case being used for equality comparison:
*
*
*
* Some(2) was not equal to Some(1)
*
*
*
* Being negative
*
*
* If you wish to check the opposite of some condition, you can simply insert not in the expression.
* Here are a few examples:
*
*
*
* result must not be (null)
* sum must not be <= (10)
* mylist must not equal (yourList)
* string must not startWith ("Hello")
*
*
*
* Checking that a snippet of code does not compile
*
*
* Often when creating libraries you may wish to ensure that certain arrangements of code that
* represent potential “user errors” do not compile, so that your library is more error resistant.
* ScalaTest Matchers trait includes the following syntax for that purpose:
*
*
*
* "val a: String = 1" mustNot compile
*
*
*
* Although this syntax is implemented with a macro that determines at compile time whether
* the snippet of code represented by the string type checks, errors (i.e.,
* snippets of code that do type check) are reported as test failures at runtime.
*
*
*
* Logical expressions with and and or
*
*
* You can also combine matcher expressions with and and/or or, however,
* you must place parentheses or curly braces around the and or or expression. For example,
* this and-expression would not compile, because the parentheses are missing:
*
*
*
* map must contain key ("two") and not contain value (7) // ERROR, parentheses missing!
*
*
*
* Instead, you need to write:
*
*
*
* map must (contain key ("two") and not contain value (7))
*
*
*
* Here are some more examples:
*
*
*
* number must (be > (0) and be <= (10))
* option must (equal (Some(List(1, 2, 3))) or be (None))
* string must (
* equal ("fee") or
* equal ("fie") or
* equal ("foe") or
* equal ("fum")
* )
*
*
*
* Two differences exist between expressions composed of these and and or operators and the expressions you can write
* on regular Booleans using its && and || operators. First, expressions with and
* and or do not short-circuit. The following contrived expression, for example, would print "hello, world!":
*
*
*
* "yellow" must (equal ("blue") and equal { println("hello, world!"); "green" })
*
*
*
* In other words, the entire and or or expression is always evaluated, so you'll see any side effects
* of the right-hand side even if evaluating
* only the left-hand side is enough to determine the ultimate result of the larger expression. Failure messages produced by these
* expressions will "short-circuit," however,
* mentioning only the left-hand side if that's enough to determine the result of the entire expression. This "short-circuiting" behavior
* of failure messages is intended
* to make it easier and quicker for you to ascertain which part of the expression caused the failure. The failure message for the previous
* expression, for example, would be:
*
*
*
* "yellow" did not equal "blue"
*
*
*
* Most likely this lack of short-circuiting would rarely be noticeable, because evaluating the right hand side will usually not
* involve a side effect. One situation where it might show up, however, is if you attempt to and a null check on a variable with an expression
* that uses the variable, like this:
*
*
*
* map must (not be (null) and contain key ("ouch"))
*
*
*
* If map is null, the test will indeed fail, but with a NullPointerException, not a
* TestFailedException. Here, the NullPointerException is the visible right-hand side effect. To get a
* TestFailedException, you would need to check each assertion separately:
*
*
*
* map must not be (null)
* map must contain key ("ouch")
*
*
*
* If map is null in this case, the null check in the first expression will fail with
* a TestFailedException, and the second expression will never be executed.
*
*
*
* The other difference with Boolean operators is that although && has a higher precedence than ||,
* and and or
* have the same precedence. Thus although the Boolean expression (a || b && c) will evaluate the && expression
* before the || expression, like (a || (b && c)), the following expression:
*
*
*
* traversable must (contain (7) or contain (8) and have size (9))
*
*
*
* Will evaluate left to right, as:
*
*
*
* traversable must ((contain (7) or contain (8)) and have size (9))
*
*
*
* If you really want the and part to be evaluated first, you'll need to put in parentheses, like this:
*
*
*
* traversable must (contain (7) or (contain (8) and have size (9)))
*
*
*
* Working with Options
*
*
* ScalaTest matchers has no special support for Options, but you can
* work with them quite easily using syntax shown previously. For example, if you wish to check
* whether an option is None, you can write any of:
*
*
*
* option mustEqual None
* option mustBe None
* option must not be defined
* option mustBe empty
*
*
*
* If you wish to check an option is defined, and holds a specific value, you can write either of:
*
*
*
* option mustEqual Some("hi")
* option mustBe Some("hi")
*
*
*
* If you only wish to check that an option is defined, but don't care what it's value is, you can write:
*
*
*
* option mustBe defined
*
*
*
* If you mix in (or import the members of) OptionValues,
* you can write one statement that indicates you believe an option must be defined and then say something else about its value. Here's an example:
*
*
*
* import org.scalatest.OptionValues._
* option.value must be < 7
*
*
*
* Checking arbitrary properties with have
*
*
* Using have, you can check properties of any type, where a property is an attribute of any
* object that can be retrieved either by a public field, method, or JavaBean-style get
* or is method, like this:
*
*
*
* book must have (
* 'title ("Programming in Scala"),
* 'author (List("Odersky", "Spoon", "Venners")),
* 'pubYear (2008)
* )
*
*
*
* This expression will use reflection to ensure the title, author, and pubYear properties of object book
* are equal to the specified values. For example, it will ensure that book has either a public Java field or method
* named title, or a public method named getTitle, that when invoked (or accessed in the field case) results
* in a the string "Programming in Scala". If all specified properties exist and have their expected values, respectively,
* execution will continue. If one or more of the properties either does not exist, or exists but results in an unexpected value,
* a TestFailedException will be thrown that explains the problem. (For the details on how a field or method is selected during this
* process, see the documentation for HavePropertyMatcherGenerator.)
*
*
*
* When you use this syntax, you must place one or more property values in parentheses after have, seperated by commas, where a property
* value is a symbol indicating the name of the property followed by the expected value in parentheses. The only exceptions to this rule is the syntax
* for checking size and length shown previously, which does not require parentheses. If you forget and put parentheses in, however, everything will
* still work as you'd expect. Thus instead of writing:
*
*
*
* array must have length (3)
* set must have size (90)
*
*
*
* You can alternatively, write:
*
*
*
* array must have (length (3))
* set must have (size (90))
*
*
*
* If a property has a value different from the specified expected value, a TestFailedError will be thrown
* with a detailed message that explains the problem. For example, if you assert the following on
* a book whose title is Moby Dick:
*
*
*
* book must have ('title ("A Tale of Two Cities"))
*
*
*
* You'll get a TestFailedException with this detail message:
*
*
*
* The title property had value "Moby Dick", instead of its expected value "A Tale of Two Cities",
* on object Book("Moby Dick", "Melville", 1851)
*
*
*
* If you prefer to check properties in a type-safe manner, you can use a HavePropertyMatcher.
* This would allow you to write expressions such as:
*
*
*
* book must have (
* title ("Programming in Scala"),
* author (List("Odersky", "Spoon", "Venners")),
* pubYear (2008)
* )
*
*
*
* These expressions would fail to compile if must is used on an inappropriate type, as determined
* by the type parameter of the HavePropertyMatcher being used. (For example, title in this example
* might be of type HavePropertyMatcher[org.publiclibrary.Book]. If used with an appropriate type, such an expression will compile
* and at run time the property method or field will be accessed directly; i.e., no reflection will be used.
* See the documentation for HavePropertyMatcher for more information.
*
*
*
* Using length and size with HavePropertyMatchers
*
*
* If you want to use length or size syntax with your own custom HavePropertyMatchers, you
* can do so, but you must write (of [“the type”]) afterwords. For example, you could write:
*
*
*
* book must have (
* title ("A Tale of Two Cities"),
* length (220) (of [Book]),
* author ("Dickens")
* )
*
*
*
* Prior to ScalaTest 2.0, “length (22)” yielded a HavePropertyMatcher[Any, Int] that used reflection to dynamically look
* for a length field or getLength method. In ScalaTest 2.0, “length (22)” yields a
* MatcherFactory1[Any, Length], so it is no longer a HavePropertyMatcher. The (of [<type>]) syntax converts the
* the MatcherFactory1[Any, Length] to a HavePropertyMatcher[<type>, Int].
*
*
*
* Using custom matchers
*
*
* If none of the built-in matcher syntax (or options shown so far for extending the syntax) satisfy a particular need you have, you can create
* custom Matchers that allow
* you to place your own syntax directly after must. For example, class java.io.File has a method isHidden, which
* indicates whether a file of a certain path and name is hidden. Because the isHidden method takes no parameters and returns Boolean,
* you can call it using be with a symbol or BePropertyMatcher, yielding assertions like:
*
*
*
* file must be ('hidden) // using a symbol
* file must be (hidden) // using a BePropertyMatcher
*
*
*
* If it doesn't make sense to have your custom syntax follow be, you might want to create a custom Matcher
* instead, so your syntax can follow must directly. For example, you might want to be able to check whether
* a java.io.File's name ends with a particular extension, like this:
*
*
*
* // using a plain-old Matcher
* file must endWithExtension ("txt")
*
*
*
* ScalaTest provides several mechanism to make it easy to create custom matchers, including ways to compose new matchers
* out of existing ones complete with new error messages. For more information about how to create custom
* Matchers, please see the documentation for the Matcher trait.
*
*
*
* Checking for expected exceptions
*
*
* Sometimes you need to test whether a method throws an expected exception under certain circumstances, such
* as when invalid arguments are passed to the method. With Matchers mixed in, you can
* check for an expected exception like this:
*
*
*
* an [IndexOutOfBoundsException] must be thrownBy s.charAt(-1)
*
*
*
* If charAt throws an instance of StringIndexOutOfBoundsException,
* this expression will result in that exception. But if charAt completes normally, or throws a different
* exception, this expression will complete abruptly with a TestFailedException.
*
*
* If you need to further isnpect an expected exception, you can capture it using this syntax:
*
*
*
* val thrown = the [IndexOutOfBoundsException] thrownBy s.charAt(-1)
*
*
*
* This expression returns the caught exception so that you can inspect it further if you wish, for
* example, to ensure that data contained inside the exception has the expected values. Here's an
* example:
*
*
*
* thrown.getMessage must equal ("String index out of range: -1")
*
*
*
* If you prefer you can also capture and inspect an expected exception in one statement, like this:
*
*
*
* the [ArithmeticException] thrownBy 1 / 0 must have message "/ by zero"
* the [IndexOutOfBoundsException] thrownBy {
* s.charAt(-1)
* } must have message "String index out of range: -1"
*
*
*
* You can also state that no exception must be thrown by some code, like this:
*
*
*
* noException must be thrownBy 0 / 1
*
*
*
* Note: the following syntax from ScalaTest 1.x has been deprecated:
*
*
*
* evaluating { s.charAt(-1) } must produce [IndexOutOfBoundsException]
*
*
*
* Such uses will continue to work during the deprecation cycle, but support for this syntax will
* eventually be removed in a future version of ScalaTest. Please change all uses to
* a corresponding use of the syntax described previously in this section.
*
Those pesky parens
*
*
* Perhaps the most tricky part of writing assertions using ScalaTest matchers is remembering
* when you need or don't need parentheses, but bearing in mind a few simple rules should help.
* It is also reassuring to know that if you ever leave off a set of parentheses when they are
* required, your code will not compile. Thus the compiler will help you remember when you need the parens.
* That said, the rules are:
*
*
*
* 1. Although you don't always need them, you may choose to always put parentheses
* around right-hand values, such as the 7 in num must equal (7):
*
*
*
* result must equal (4)
* array must have length (3)
* book must have (
* 'title ("Programming in Scala"),
* 'author (List("Odersky", "Spoon", "Venners")),
* 'pubYear (2008)
* )
* option must be ('defined)
* catMap must (contain key (9) and contain value ("lives"))
* keyEvent must be an ('actionKey)
* javaSet must have size (90)
*
*
*
* 2. Except for length, size and message, you must always put parentheses around
* the list of one or more property values following a have:
*
*
*
* file must (exist and have ('name ("temp.txt")))
* book must have (
* title ("Programming in Scala"),
* author (List("Odersky", "Spoon", "Venners")),
* pubYear (2008)
* )
* javaList must have length (9) // parens optional for length and size
*
*
*
* 3. You must always put parentheses around and and or expressions, as in:
*
*
*
* catMap must (contain key (9) and contain value ("lives"))
* number must (equal (2) or equal (4) or equal (8))
*
*
*
* 4. Although you don't always need them, you may choose to always put parentheses
* around custom Matchers when they appear directly after not:
*
*
*
* file must exist
* file must not (exist)
* file must (exist and have ('name ("temp.txt")))
* file must (not (exist) and have ('name ("temp.txt"))
* file must (have ('name ("temp.txt") or exist)
* file must (have ('name ("temp.txt") or not (exist))
*
*
*
* That's it. With a bit of practice it should become natural to you, and the compiler will always be there to tell you if you
* forget a set of needed parentheses.
*
*
*
* Note: ScalaTest's matchers are in part inspired by the matchers of RSpec,
* Hamcrest, and
* specs2, and its “mustNot compile” syntax
* by the illTyped macro of shapeless.

* If a method, it must take no parameters. If multiple candidates are found,
* the apply method will select based on the following algorithm:
*
