/**
* A sister trait to org.scalatest.FlatSpec that can pass a fixture object into its tests.
*
*
* The purpose of fixture.FlatSpec and its subtraits is to facilitate writing tests in
* a functional style. Some users may prefer writing tests in a functional style in general, but one
* particular use case is parallel test execution (See ParallelTestExecution). To run
* tests in parallel, your test class must
* be thread safe, and a good way to make it thread safe is to make it functional. A good way to
* write tests that need common fixtures in a functional style is to pass the fixture objects into the tests,
* the style enabled by the fixture.Suite family of traits.
*
*
*
* Trait org.scalatest.fixture.FlatSpec behaves similarly to trait org.scalatest.FlatSpec, except that tests may have a
* fixture parameter. The type of the
* fixture parameter is defined by the abstract FixtureParam type, which is declared as a member of this trait.
* This trait also declares an abstract withFixture method. This withFixture method
* takes a OneArgTest, which is a nested trait defined as a member of this trait.
* OneArgTest has an apply method that takes a FixtureParam.
* This apply method is responsible for running a test.
* This trait's runTest method delegates the actual running of each test to withFixture, passing
* in the test code to run via the OneArgTest argument. The withFixture method (abstract in this trait) is responsible
* for creating the fixture argument and passing it to the test function.
*
*
*
* Subclasses of this trait must, therefore, do three things differently from a plain old org.scalatest.FlatSpec:
*
*
*
* - define the type of the fixture parameter by specifying type
FixtureParam
* - define the
withFixture(OneArgTest) method
* - write tests that take a fixture parameter
* - (You can also define tests that don't take a fixture parameter.)
*
*
*
* Here's an example:
*
*
*
* import org.scalatest.fixture
* import collection.mutable.Stack
* import java.util.NoSuchElementException
*
* class StackSpec extends fixture.FlatSpec {
*
* // 1. define type FixtureParam
* type FixtureParam = Stack[Int]
*
* // 2. define the withFixture method
* def withFixture(test: OneArgTest) {
* val stack = new Stack[Int]
* stack.push(1)
* stack.push(2)
* test(stack) // "loan" the fixture to the test
* }
*
* // 3. write tests that take a fixture parameter
* "A Stack" should "pop a value" in { stack =>
* val top = stack.pop()
* assert(top === 2)
* assert(stack.size === 1)
* }
*
* it should "push a value" in { stack =>
* stack.push(9)
* assert(stack.size === 3)
* assert(stack.head === 9)
* }
*
* // 4. You can also write tests that don't take a fixture parameter.
* it should "complain if popped when empty" in () {
* intercept[NoSuchElementException] {
* (new Stack[Int]).pop()
* }
* }
* }
*
*
*
* In the previous example, withFixture creates and initializes a stack, then invokes the test function, passing in
* the stack. In addition to setting up a fixture before a test, the withFixture method also allows you to
* clean it up afterwards, if necessary. If you need to do some clean up that must happen even if a test
* fails, you should invoke the test function from inside a try block and do the cleanup in a
* finally clause, like this:
*
*
*
* def withFixture(test: OneArgTest) {
* val resource = someResource.open() // set up the fixture
* try {
* test(resource) // if the test fails, test(...) will throw an exception
* }
* finally {
* // clean up the fixture no matter whether the test succeeds or fails
* resource.close()
* }
* }
*
*
*
* The reason you must perform cleanup in a finally clause is that withFixture is called by
* runTest, which expects an exception to be thrown to indicate a failed test. Thus when you invoke
* the test function, it may complete abruptly with an exception. The finally clause will
* ensure the fixture cleanup happens as that exception propagates back up the call stack to runTest.
*
*
*
* If the fixture you want to pass into your tests consists of multiple objects, you will need to combine
* them into one object to use this trait. One good approach to passing multiple fixture objects is
* to encapsulate them in a case class. Here's an example:
*
*
*
* import org.scalatest.fixture
* import scala.collection.mutable.ListBuffer
*
* class ExampleSpec extends fixture.FlatSpec {
*
* case class F(builder: StringBuilder, buffer: ListBuffer[String])
* type FixtureParam = F
*
* def withFixture(test: OneArgTest) {
*
* // Create needed mutable objects
* val stringBuilder = new StringBuilder("ScalaTest is ")
* val listBuffer = new ListBuffer[String]
*
* // Invoke the test function, passing in the mutable objects
* test(F(stringBuilder, listBuffer))
* }
*
* "Testing" should "be easy" in { f =>
* f.builder.append("easy!")
* assert(f.builder.toString === "ScalaTest is easy!")
* assert(f.buffer.isEmpty)
* f.buffer += "sweet"
* }
*
* "Testing" should "be fun" in { f =>
* f.builder.append("fun!")
* assert(f.builder.toString === "ScalaTest is fun!")
* assert(f.buffer.isEmpty)
* }
* }
*
*
* Configuring fixtures and tests
*
*
* Sometimes you may want to write tests that are configurable. For example, you may want to write
* a suite of tests that each take an open temp file as a fixture, but whose file name is specified
* externally so that the file name can be can be changed from run to run. To accomplish this
* the OneArgTest trait has a configMap
* method, which will return a Map[String, Any] from which configuration information may be obtained.
* The runTest method of this trait will pass a OneArgTest to withFixture
* whose configMap method returns the configMap passed to runTest.
* Here's an example in which the name of a temp file is taken from the passed configMap:
*
*
*
* import org.scalatest.fixture
* import java.io.FileReader
* import java.io.FileWriter
* import java.io.File
*
* class ExampleSpec extends fixture.FlatSpec {
*
* type FixtureParam = FileReader
* def withFixture(test: OneArgTest) {
*
* require(
* test.configMap.contains("TempFileName"),
* "This suite requires a TempFileName to be passed in the configMap"
* )
*
* // Grab the file name from the configMap
* val FileName = test.configMap("TempFileName").asInstanceOf[String]
*
* // Set up the temp file needed by the test
* val writer = new FileWriter(FileName)
* try {
* writer.write("Hello, test!")
* }
* finally {
* writer.close()
* }
*
* // Create the reader needed by the test
* val reader = new FileReader(FileName)
*
* try {
* // Run the test using the temp file
* test(reader)
* }
* finally {
* // Close and delete the temp file
* reader.close()
* val file = new File(FileName)
* file.delete()
* }
* }
*
* "A file" can "be read" in { reader =>
* var builder = new StringBuilder
* var c = reader.read()
* while (c != -1) {
* builder.append(c.toChar)
* c = reader.read()
* }
* assert(builder.toString === "Hello, test!")
* }
*
* "The first char of a file" can "be read" in { reader =>
* assert(reader.read() === 'H')
* }
* }
*
*
*
* If you want to pass into each test the entire configMap that was passed to runTest, you
* can mix in trait ConfigMapFixture. See the documentation
* for ConfigMapFixture for the details, but here's a quick
* example of how it looks:
*
*
*
* import org.scalatest.fixture
* import org.scalatest.fixture.ConfigMapFixture
*
* class ExampleSpec extends fixture.FlatSpec with ConfigMapFixture {
*
* "The config map" should "contain hello" in { configMap =>
* // Use the configMap passed to runTest in the test
* assert(configMap.contains("hello"))
* }
*
* it should "contain world" in { configMap =>
* assert(configMap.contains("world"))
* }
* }
*
*
* Providing multiple fixtures
*
*
* If different tests in the same fixture.FlatSpec need different shared fixtures, you can use the loan pattern to supply to
* each test just the fixture or fixtures it needs. First select the most commonly used fixture objects and pass them in via the
* FixtureParam. Then for each remaining fixture needed by multiple tests, create a with<fixture name>
* method that takes a function you will use to pass the fixture to the test. Lasty, use the appropriate
* with<fixture name> method or methods in each test.
*
*
*
* In the following example, the FixtureParam is set to Map[String, Any] by mixing in ConfigMapFixture.
* The withFixture method in trait ConfigMapFixture will pass the config map to any test that needs it.
* In addition, some tests in the following example need a Stack[Int] and others a Stack[String].
* The withIntStack method takes
* care of supplying the Stack[Int] to those tests that need it, and the withStringStack method takes care
* of supplying the Stack[String] fixture. Here's how it looks:
*
*
*
* import org.scalatest.fixture
* import org.scalatest.fixture.ConfigMapFixture
* import collection.mutable.Stack
*
* class StackSpec extends fixture.FlatSpec with ConfigMapFixture {
*
* def withIntStack(test: Stack[Int] => Any) {
* val stack = new Stack[Int]
* stack.push(1)
* stack.push(2)
* test(stack) // "loan" the Stack[Int] fixture to the test
* }
*
* def withStringStack(test: Stack[String] => Any) {
* val stack = new Stack[String]
* stack.push("one")
* stack.push("two")
* test(stack) // "loan" the Stack[String] fixture to the test
* }
*
* "A Stack" must "pop an Int value" in { () => // This test doesn't need the configMap fixture, ...
* withIntStack { stack =>
* val top = stack.pop() // But it needs the Stack[Int] fixture.
* assert(top === 2)
* assert(stack.size === 1)
* }
* }
*
* it must "push an Int value" in { configMap =>
* withIntStack { stack =>
* val iToPush = // This test uses the configMap fixture...
* configMap("IntToPush").toString.toInt
* stack.push(iToPush) // And also uses the Stack[Int] fixture.
* assert(stack.size === 3)
* assert(stack.head === iToPush)
* }
* }
*
* it must "pop a String value" in { () => // This test doesn't need the configMap fixture, ...
* withStringStack { stack =>
* val top = stack.pop() // But it needs the Stack[String] fixture.
* assert(top === "two")
* assert(stack.size === 1)
* }
* }
*
* it must "push a String value" in { configMap =>
* withStringStack { stack =>
* val sToPush = // This test uses the configMap fixture...
* configMap("StringToPush").toString
* stack.push(sToPush) // And also uses the Stack[Int] fixture.
* assert(stack.size === 3)
* assert(stack.head === sToPush)
* }
* }
* }
*
*
*
* If you run the previous class in the Scala interpreter, you'll see:
*
*
*
* scala> import org.scalatest._
* import org.scalatest._
*
* scala> run(new StackSpec, configMap = Map("IntToPush" -> 9, "StringToPush" -> "nine"))
* StackSpec:
* A Stack
* - must pop an Int value
* - must push an Int value
* - must pop a String value
* - must push a String value

* For example, this class enables syntax such as the following tagged test registration
* in shorthand form:
*
*
*
* "A Stack (when empty)" should "be empty" taggedAs() in { ... }
* ^
*
*
*
* This class also enables syntax such as the following tagged, ignored test registration
* in shorthand form:
*
*
*
* "A Stack (when empty)" should "be empty" taggedAs(SlowTest) ignore { ... }
* ^
*
*
*
* This class is used via an implicit conversion (named convertToInAndIgnoreMethodsAfterTaggedAs)
* from ResultOfTaggedAsInvocation. The ResultOfTaggedAsInvocation class
* does not declare any methods named in, because the
* type passed to in differs in a FlatSpec and a fixture.FlatSpec.
* A fixture.FlatSpec needs two in methods, one that takes a no-arg
* test function and another that takes a one-arg test function (a test that takes a
* FixtureParam as its parameter). By constrast, a FlatSpec needs
* only one in method that takes a by-name parameter. As a result,
* FlatSpec and fixture.FlatSpec each provide an implicit conversion
* from ResultOfTaggedAsInvocation to a type that provides the appropriate
* in methods.
