* One of the parameters to
* *Suite
'srun
method is aReporter
, which * will collect and report information about the running suite of tests. * Information about suites and tests that were run, whether tests succeeded or failed, * and tests that were ignored will be passed to theReporter
as the suite runs. * Most often the reporting done by default will be sufficient, but * occasionally you may wish to provide custom information to theReporter
from a test. * For this purpose, anInformer
that will forward information * to the currentReporter
is provided via theinfo
parameterless method. * You can pass the extra information to theInformer
via itsapply
method. * TheInformer
will then pass the information to theReporter
via anInfoProvided
event. * Here's an example that shows both a direct use as well as an indirect use through the methods * ofGivenWhenThen
: ** package org.scalatest.examples.suite.info * * import collection.mutable * import org.scalatest._ * * class SetSuite extends Suite with GivenWhenThen { * * def `test: an element can be added to an empty mutable Set` { * * given("an empty mutable Set") * val set = mutable.Set.empty[String] * * when("an element is added") * set += "clarity" * * then("the Set should have size 1") * assert(set.size === 1) * * and("the Set should contain the added element") * assert(set.contains("clarity")) * * info("That's all folks!") * } * } ** * If you run thisSuite

* ** Trait
* -------------- *Suite
also carries aDocumenter
namedmarkup
, which * you can use to transmit markup text to theReporter
. *Assertions and
* *=
=
=
* Inside test methods in a
* *Suite
, you can write assertions by invokingassert
and passing in aBoolean
expression, * such as: ** val left = 2 * val right = 1 * assert(left == right) ** ** If the passed expression is
* *true
,assert
will return normally. Iffalse
, *assert
will complete abruptly with aTestFailedException
. This exception is usually not caught * by the test method, which means the test method itself will complete abruptly by throwing theTestFailedException
. Any * test method that completes abruptly with an exception is considered a failed * test. A test method that returns normally is considered a successful test. ** If you pass a
* *Boolean
expression toassert
, a failed assertion will be reported, but without * reporting the left and right values. You can alternatively encode these values in aString
passed as * a second argument toassert
, as in: ** val left = 2 * val right = 1 * assert(left == right, left + " did not equal " + right) ** ** Using this form of
* *assert
, the failure report will include the left and right values, * helping you debug the problem. However, ScalaTest provides the===
operator to make this easier. * (The===
operator is defined in traitAssertions
which traitSuite
extends.) * You use it like this: ** val left = 2 * val right = 1 * assert(left === right) ** ** Because you use
* *===
here instead of==
, the failure report will include the left * and right values. For example, the detail message in the thrownTestFailedException
from theassert
* shown previously will include, "2 did not equal 1". * From this message you will know that the operand on the left had the value 2, and the operand on the right had the value 1. ** If you're familiar with JUnit, you would use
* *===
* in a ScalaTestSuite
where you'd useassertEquals
in a JUnitTestCase
. * The===
operator is made possible by an implicit conversion fromAny
* toEqualizer
. If you're curious to understand the mechanics, see the documentation for *Equalizer
and theconvertToEqualizer
method. *Expected results
* * Although===
provides a natural, readable extension to Scala'sassert
mechanism, * as the operands become lengthy, the code becomes less readable. In addition, the===
comparison * doesn't distinguish between actual and expected values. The operands are just calledleft
andright
, * because if one were namedexpected
and the otheractual
, it would be difficult for people to * remember which was which. To help with these limitations of assertions,Suite
includes a method calledassertResult
that * can be used as an alternative toassert
with===
. To useassertResult
, you place * the expected value in parentheses afterassertResult
, followed by curly braces containing code * that should result in the expected value. For example: * ** val a = 5 * val b = 2 * assertResult(2) { * a - b * } ** ** In this case, the expected value is
* *2
, and the code being tested isa - b
. This expectation will fail, and * the detail message in theTestFailedException
will read, "Expected 2, but got 3." *Intercepted 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. You can do this in the JUnit style, like this: *
* ** val s = "hi" * try { * s.charAt(-1) * fail() * } * catch { * case _: IndexOutOfBoundsException => // Expected, so continue * } ** ** If
* *charAt
throwsIndexOutOfBoundsException
as expected, control will transfer * to the catch case, which does nothing. If, however,charAt
fails to throw an exception, * the next statement,fail()
, will be executed. Thefail
method always completes abruptly with * aTestFailedException
, thereby signaling a failed test. ** To make this common use case easier to express and read, ScalaTest provides an
* *intercept
* method. You use it like this: ** val s = "hi" * intercept[IndexOutOfBoundsException] { * s.charAt(-1) * } ** ** This code behaves much like the previous example. If
* *charAt
throws an instance ofIndexOutOfBoundsException
, *intercept
will return that exception. But ifcharAt
completes normally, or throws a different * exception,intercept
will complete abruptly with aTestFailedException
. Theintercept
method 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: ** val s = "hi" * val caught = * intercept[IndexOutOfBoundsException] { * s.charAt(-1) * } * assert(caught.getMessage === "String index out of range: -1") ** *Using matchers and other assertions
* ** ScalaTest also supports another style of assertions via its matchers DSL. By mixing in * trait
* *Matchers
, you can * write suites that look like: ** package org.scalatest.examples.suite.matchers * * import org.scalatest._ * * class SetSuite extends Suite with Matchers { * * def `test: an empty Set should have size 0` { * Set.empty.size should equal (0) * } * * def `test: invoking head on an empty Set should produce NoSuchElementException` { * a [NoSuchElementException] should be thrownBy { Set.empty.head } * } * } ** *If you prefer the word "
* *must
" to the word "should
," you can alternatively mix in * traitMustMatchers
. ** If you are comfortable with assertion mechanisms from other test frameworks, chances * are you can use them with ScalaTest. Any assertion mechanism that indicates a failure with an exception * can be used as is with ScalaTest. For example, to use the
*/ /** * A suite of tests. AassertEquals
* methods provided by JUnit or TestNG, simply import them and use them. (You will of course need * to include the relevant JAR file for the framework whose assertions you want to use on either the * classpath or runpath when you run your tests.) *Suite
instance encapsulates a conceptual * suite (i.e., a collection) of tests. * ** This trait provides an interface composed of "lifecycle methods" that allow suites of tests to be run. * Its implementation enables a default way of writing and executing tests. Subtraits and subclasses can * override
* *Suite
's lifecycle methods to enable other ways of writing and executing tests. *Nested suites
* ** A
* *Suite
can refer to a collection of otherSuite
s, * which are called nestedSuite
s. Those nestedSuite
s can in turn have * their own nestedSuite
s, and so on. Large test suites can be organized, therefore, as a tree of * nestedSuite
s. * This trait'srun
method, in addition to invoking its * test methods, invokesrun
on each of its nestedSuite
s. ** A
* *List
of aSuite
's nestedSuite
s can be obtained by invoking its *nestedSuites
method. If you wish to create aSuite
that serves as a * container for nestedSuite
s, whether or not it has test methods of its own, simply overridenestedSuites
* to return aList
of the nestedSuite
s. Because this is a common use case, ScalaTest provides * a convenienceSuites
class, which takes a variable number of nestedSuite
s as constructor * parameters. Here's an example: ** package org.scalatest.examples.suite.nested * * import org.scalatest._ * * class ASuite extends FunSuite { * test("A should have ASCII value 41 hex") { * assert('A' === 0x41) * } * test("a should have ASCII value 61 hex") { * assert('a' === 0x61) * } * } * class BSuite extends FunSuite { * test("B should have ASCII value 42 hex") { * assert('B' === 0x42) * } * test("b should have ASCII value 62 hex") { * assert('b' === 0x62) * } * } * class CSuite extends FunSuite { * test("C should have ASCII value 43 hex") { * assert('C' === 0x43) * } * test("c should have ASCII value 63 hex") { * assert('c' === 0x63) * } * } * * class ASCIISuite extends Suites( * new ASuite, * new BSuite, * new CSuite * ) ** ** If you now run
* *ASCIISuite
: ** scala> org.scalatest.run(new ASCIISuite) ** ** You will see reports printed to the standard output that indicate the nested * suites—
* *ASuite
,BSuite
, and *CSuite
—were run: ** ASCIISuite: * ASuite: * - A should have ASCII value 41 hex * - a should have ASCII value 61 hex * BSuite: * - B should have ASCII value 42 hex * - b should have ASCII value 62 hex * CSuite: * - C should have ASCII value 43 hex * - c should have ASCII value 63 hex *
* ** Note that
* *Runner
can discoverSuite
s automatically, so you need not * necessarily define nestedSuites
explicitly. See the documentation * forRunner
for more information. *The config map
* ** In some cases you may need to pass information to a suite of tests. * For example, perhaps a suite of tests needs to grab information from a file, and you want * to be able to specify a different filename during different runs. You can accomplish this in ScalaTest by passing * the filename in a config map of key-value pairs, which is passed to
* *run
as aConfigMap
. * The values in the config map are called "config objects," because they can be used to configure * suites, reporters, and tests. ** You can specify a string config object is via the ScalaTest
* *Runner
, either via the command line * or ScalaTest's ant task. * (See the documentation for Runner for information on how to specify * config objects on the command line.) * The config map is passed torun
,runNestedSuites
,runTests
, andrunTest
, * so one way to access it in your suite is to override one of those methods. If you need to use the config map inside your tests, you * can access it from theNoArgTest
passed towithFixture
, or theOneArgTest
passed to *withFixture
in the traits in theorg.scalatest.fixture
package. (See the * documentation forfixture.Suite
* for instructions on how to access the config map in tests.) *Executing suites in parallel
* ** The
* * *run
method takes as one of its parameters an optionalDistributor
. If * aDistributor
is passed in, this trait's implementation ofrun
puts its nested *Suite
s into the distributor rather than executing them directly. The caller ofrun
* is responsible for ensuring that some entity runs theSuite
s placed into the * distributor. The-P
command line parameter toRunner
, for example, will cause *Suite
s put into theDistributor
to be run in parallel via a pool of threads. * If you wish to execute the tests themselves in parallel, mix inParallelTestExecution
. *"Run-aborting" exceptions
* ** The Javadoc documentation for
* *java.lang.Error
states: ** An* *Error
is a subclass ofThrowable
that indicates serious problems that a reasonable application * should not try to catch. Most * such errors are abnormal conditions. ** Because
* *Error
s are used to denote serious errors, traitSuite
and its subtypes in the ScalaTest API * do not always treat a test that completes abruptly with anError
as a test failure, but sometimes as an indication * that serious problems have arisen that should cause the run to abort. For example, if a test completes abruptly with an *OutOfMemoryError
, it will not be reported as a test failure, but will instead cause the run to abort. Because not * everyone usesError
s only to represent serious * problems, however, ScalaTest only behaves this way for the following run-aborting exception types (and their subclasses): **
* *- *
java.lang.annotation.AnnotationFormatError
- *
java.awt.AWTError
- *
java.nio.charset.CoderMalfunctionError
- *
javax.xml.parsers.FactoryConfigurationError
- *
java.lang.LinkageError
- *
java.lang.ThreadDeath
- *
javax.xml.transform.TransformerFactoryConfigurationError
- *
java.lang.VirtualMachineError
* The previous list includes all
* *Error
s that exist as part of Java 1.5 API, excludingjava.lang.AssertionError
. * ScalaTest does treat a thrownAssertionError
as an indication of a test failure. In addition, any other *Error
that is not an instance of a type mentioned in the previous list will be caught by theSuite
traits * in the ScalaTest API and reported as the cause of a test failure. ** Although trait
* * *Suite
and all its subtypes in the ScalaTest API consistently behave this way with regard toError
s, * this behavior is not required by the contract ofSuite
. Subclasses and subtraits that you define, for example, may treat all *Error
s as test failures, or indicate errors in some other way that has nothing to do with exceptions. *Extensibility
* ** Trait
* *Suite
provides default implementations of its methods that should * be sufficient for most applications, but many methods can be overridden when desired. Here's * a summary of the methods that are intended to be overridden: **
* *- *
run
- override this method to define custom ways to run suites of * tests.- *
runNestedSuites
- override this method to define custom ways to run nested suites.- *
runTests
- override this method to define custom ways to run a suite's tests.- *
runTest
- override this method to define custom ways to run a single named test.- *
testNames
- override this method to specify theSuite
's test names in a custom way.- *
tags
- override this method to specify theSuite
's test tags in a custom way.- *
nestedSuites
- override this method to specify theSuite
's nestedSuite
s in a custom way.- *
suiteName
- override this method to specify theSuite
's name in a custom way.- *
expectedTestCount
- override this method to count thisSuite
's expected tests in a custom way.* For example, this trait's implementation of
* *testNames
performs reflection to discover methods starting withtest
, * and places these in aSet
whose iterator returns the names in alphabetical order. If you wish to run tests in a different * order in a particularSuite
, perhaps because a test namedtestAlpha
can only succeed after a test named *testBeta
has run, you can overridetestNames
so that it returns aSet
whose iterator returns *testBeta
beforetestAlpha
. (This trait's implementation ofrun
will invoke tests * in the order they come out of thetestNames
Set
iterator.) ** Alternatively, you may not like starting your test methods with
* *test
, and prefer using@Test
annotations in * the style of Java's JUnit 4 or TestNG. If so, you can overridetestNames
to discover tests using either of these two APIs *@Test
annotations, or one of your own invention. (This is in fact * howorg.scalatest.junit.JUnitSuite
andorg.scalatest.testng.TestNGSuite
work.) ** Moreover, test in ScalaTest does not necessarily mean test method. A test can be anything that can be given a name, * that starts and either succeeds or fails, and can be ignored. In
* *org.scalatest.FunSuite
, for example, tests are represented * as function values. This * approach might look foreign to JUnit users, but may feel more natural to programmers with a functional programming background. * To facilitate this style of writing tests,FunSuite
overridestestNames
,runTest
, andrun
such that you can * define tests as function values. ** You can also model existing JUnit 3, JUnit 4, or TestNG tests as suites of tests, thereby incorporating tests written in Java into a ScalaTest suite. * The "wrapper" classes in packages

* *run
on itself, passing in values that can be configured via the parameters to this * method, all of which have default values. This behavior is convenient when working with ScalaTest in the Scala interpreter. * Here's a summary of this method's parameters and how you can use them: ** The

torun
, and only that test * will be run. Thus to run all tests in a suite from the Scala interpreter, you can write: ** scala> (new ExampleSuite).execute() ** ** (The above syntax actually invokes the overloaded parameterless form of
* *execute
, which calls this form with its default parameter values.) * To run just the test named"my favorite test"
in a suite from the Scala interpreter, you would write: ** scala> (new ExampleSuite).execute("my favorite test") ** ** Or: *
* ** scala> (new ExampleSuite).execute(testName = "my favorite test") ** ** The
* *configMap
parameter ** If you provide a value for the
* *configMap
parameter, this method will pass it torun
. If not, the default value * of an emptyMap
will be passed. For more information on how to use a config map to configure your test suites, see * the config map section in the main documentation for this trait. Here's an example in which you configure * a run with the name of an input file: ** scala> (new ExampleSuite).execute(configMap = Map("inputFileName" -> "in.txt") ** ** The
* *color
parameter ** If you leave the
* *color
parameter unspecified, this method will configure the reporter it passes torun

, like this: ** scala> (new ExampleSuite).execute(color = false) ** ** The
* *durations
parameter ** If you leave the
* *durations
parameter unspecified, this method will configure the reporter it passes torun
to * not print durations for tests and suites to the standard output. If you want durations printed, specify true fordurations
, * like this: ** scala> (new ExampleSuite).execute(durations = true) ** ** The
* *shortstacks
andfullstacks
parameters ** If you leave both the
* *shortstacks
andfullstacks
parameters unspecified, this method will configure the reporter * it passes torun
to not print stack traces for failed tests if it has a stack depth that identifies the offending * line of test code. If you prefer a short stack trace (10 to 15 stack frames) to be printed with any test failure, specify true for *shortstacks
: ** scala> (new ExampleSuite).execute(shortstacks = true) ** ** For full stack traces, set
* *fullstacks
to true: ** scala> (new ExampleSuite).execute(fullstacks = true) ** ** If you specify true for both

parameter unspecified, this method will not fireRunStarting

* Note: In ScalaTest, the terms "execute" and "run" basically mean the same thing and * can be used interchangably. The reason this method isn't named
* *run
is that it takes advantage of * default arguments, and you can't mix overloaded methods and default arguments in Scala. (If namedrun
, * this method would have the same name but different arguments than the mainrun
method that * takes seven arguments. Thus it would overload and couldn't be used with default argument values.) ** Design note: This method has two "features" that may seem unidiomatic. First, the default value of
* *testName
isnull
. * Normally in Scala the type oftestName
would beOption[String]
and the default value would * beNone
, as it is in this trait'srun
method. Thenull
value is used here for two reasons. First, in * ScalaTest 1.5,execute
was changed from four overloaded methods to one method with default values, taking advantage of * the default and named parameters feature introduced in Scala 2.8. * To not break existing source code,testName
needed to have typeString
, as it did in two of the overloaded *execute
methods prior to 1.5. The other reason is thatexecute
has always been designed to be called primarily * from an interpeter environment, such as the Scala REPL (Read-Evaluate-Print-Loop). In an interpreter environment, minimizing keystrokes is king. * AString
type with anull
default value lets users typesuite.execute("my test name")
rather than *suite.execute(Some("my test name"))
, saving several keystrokes. ** The second non-idiomatic feature is that
* * @param testName the name of one test to run. * @param configMap ashortstacks
andfullstacks
are all lower case rather than * camel case. This is done to be consistent with theShell
, which also uses those forms. The reason * lower case is used in theShell
is to save keystrokes in an interpreter environment. Most Unix commands, for * example, are all lower case, making them easier and quicker to type. In the ScalaTest *Shell
, methods likeshortstacks
,fullstacks
, andnostats
, etc., are * designed to be all lower case so they feel more like shell commands than methods. *Map
of key-value pairs that can be used by the executingSuite
of tests. * @param color a boolean that configures whether output is printed in color * @param durations a boolean that configures whether test and suite durations are printed to the standard output * @param shortstacks a boolean that configures whether short stack traces should be printed for test failures * @param fullstacks a boolean that configures whether full stack traces should be printed for test failures * @param stats a boolean that configures whether test and suite statistics are printed to the standard output * * @throws NullArgumentException if the passedconfigMap

overrides runTests
s. In a Suite
* subclass that no longer invokes runTests
from run
, the
* BeforeAndAfterEach
trait is not applicable. Mixing it in would have no effect.
* By making runTests
final in such a Suite
subtrait, you make
* the attempt to mix BeforeAndAfterEach
into a subclass of your subtrait
* a compiler error. (It would fail to compile with a complaint that BeforeAndAfterEach
* is trying to override runTests
, which is a final method in your trait.)
