FixtureTestSuite

trait FixtureTestSuite extends FixtureSuite with TestSuite

The base trait for ScalaTest's synchronous testing styles that accept a fixture object passed into tests. This trait defines a withFixture lifecycle method that takes as its parameter a test function that accepts a fixture object and returns an Outcome.

The abstract withFixture method add by this trait has the following signature:

def withFixture(test: OneArgTest): Outcome

The apply method of test function interface, OneArgTest, also returns Outcome:

// In trait OneArgTest:
def apply(fixture: FixtureParam): Outcome

Because the result of a test is an Outcome, when the test function returns, the test body must have determined an outcome already. It will already be one of Succeeded, Failed, Canceled, or Pending. This is also true when withFixture(OneArgTest) returns: because the result type of withFixture(OneArgTest) is Outcome, the test has by definition already finished execution.

The recommended way to ensure cleanup is performed after a test body finishes execution is to use a try-finally clause. Using try-finally will ensure that cleanup will occur whether the test function completes abruptly by throwing a suite-aborting exception, or returns normally yielding an Outcome. Note that the only situation in which a test function will complete abruptly with an exception is if the test body throws a suite-aborting exception. Any other exception will be caught and reported as either a Failed, Canceled, or Pending.

To enable the stacking of traits that define withFixture(NoArgTest), it is a good idea to let withFixture(NoArgTest) invoke the test function instead of invoking the test function directly. To do so, you'll need to convert the OneArgTest to a NoArgTest. You can do that by passing the fixture object to the toNoArgTest method of OneArgTest. In other words, instead of writing “test(theFixture)”, you'd delegate responsibility for invoking the test function to the withFixture(NoArgTest) method of the same instance by writing:

withFixture(test.toNoArgTest(theFixture))

The withFixture method is designed to be stacked, and to enable this, you should always call the super implementation of withFixture, and let it invoke the test function rather than invoking the test function directly. In other words, instead of writing “test(...)”, you should write “super.withFixture(test)”. Thus, the recommended structure of a withFixture implementation that performs cleanup looks like this:

// Your implementation
type FixtureParam = String

override def withFixture(test: OneArgTest) = {
  // Perform setup here
  val theFixture = "hello"
  try {
    withFixture(test.toNoArgTest(theFixture)) // Invoke the test function
  } finally {
    // Perform cleanup here
  }
}

If you have no cleanup to perform, you can write withFixture like this instead:

// Your implementation
type FixtureParam = String

override def withFixture(test: NoArgTest) = {
  // Perform setup here
  val theFixture = "hello"
  withFixture(test.toNoArgTest(theFixture)) // Invoke the test function
}

If you want to perform an action only for certain outcomes, you can use a pattern match. For example, if you want to perform an action if a test fails, you'd match on Failed, like this:

// Your implementation
type FixtureParam = String

override def withFixture(test: NoArgTest) = {

  // Perform setup here
  val theFixture = "hello"

  val outcome = withFixture(test.toNoArgTest(theFixture)) // Invoke the test function

  outcome match {
    case failed: Failed =>
      // perform action that you want to occur
      // only if a test fails here
      failed
    case other => other
  }
}

If you want to change the outcome in some way in withFixture, you can also use a pattern match. For example, if a particular exception intermittently causes a test to fail, and can transform those failures into cancelations, like this:

// Your implementation
type FixtureParam = String

override def withFixture(test: NoArgTest) = {

  val theFixture = "hello"

  withFixture(test.toNoArgTest(theFixture)) match {
    case Failed(ex: ParticularException) =>
      Canceled("Muting flicker", ex)
    case other => other
  }
}

  11. macro def assert(condition: Boolean, clue: Any)(implicit prettifier: Prettifier, pos: Position): Assertion

    Assert that a boolean condition, described in String message, is true.

    Assert that a boolean condition, described in String message, is true. If the condition is true, this method returns normally. Else, it throws TestFailedException with a helpful error message appended with the String obtained by invoking toString on the specified clue as the exception's detail message.

    This method is implemented in terms of a Scala macro that will generate a more helpful error message for expressions of this form:

    • assert(a == b, "a good clue")
    • assert(a != b, "a good clue")
    • assert(a === b, "a good clue")
    • assert(a !== b, "a good clue")
    • assert(a > b, "a good clue")
    • assert(a >= b, "a good clue")
    • assert(a < b, "a good clue")
    • assert(a <= b, "a good clue")
    • assert(a startsWith "prefix", "a good clue")
    • assert(a endsWith "postfix", "a good clue")
    • assert(a contains "something", "a good clue")
    • assert(a eq b, "a good clue")
    • assert(a ne b, "a good clue")
    • assert(a > 0 && b > 5, "a good clue")
    • assert(a > 0 || b > 5, "a good clue")
    • assert(a.isEmpty, "a good clue")
    • assert(!a.isEmpty, "a good clue")
    • assert(a.isInstanceOf[String], "a good clue")
    • assert(a.length == 8, "a good clue")
    • assert(a.size == 8, "a good clue")
    • assert(a.exists(_ == 8), "a good clue")

    At this time, any other form of expression will just get a TestFailedException with message saying the given expression was false. In the future, we will enhance this macro to give helpful error messages in more situations. In ScalaTest 2.0, however, this behavior was sufficient to allow the === that returns Boolean to be the default in tests. This makes === consistent between tests and production code.

    Asserts that a given string snippet of code passes both the Scala parser and type checker.

    Although assertCompiles is implemented with a macro that determines at compile time whether the snippet of code represented by the passed string compiles, errors (i.e., snippets of code that do not compile) are reported as test failures at runtime.

    Asserts that a given string snippet of code does not pass either the Scala parser or type checker.

    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's Assertions trait includes the following syntax for that purpose:

    assertDoesNotCompile("val a: String = \"a string")

    Although assertDoesNotCompile is implemented with a macro that determines at compile time whether the snippet of code represented by the passed string doesn't compile, errors (i.e., snippets of code that do compile) are reported as test failures at runtime.

    Note that the difference between assertTypeError and assertDoesNotCompile is that assertDoesNotCompile will succeed if the given code does not compile for any reason, whereas assertTypeError will only succeed if the given code does not compile because of a type error. If the given code does not compile because of a syntax error, for example, assertDoesNotCompile will return normally but assertTypeError will throw a TestFailedException.

  17. def assertThrows[T <: AnyRef](f: => Any)(implicit classTag: ClassTag[T], pos: Position): Assertion

    Ensure that an expected exception is thrown by the passed function value.

    Ensure that an expected exception is thrown by the passed function value. The thrown exception must be an instance of the type specified by the type parameter of this method. This method invokes the passed function. If the function throws an exception that's an instance of the specified type, this method returns Succeeded. Else, whether the passed function returns normally or completes abruptly with a different exception, this method throws TestFailedException.

    Note that the type specified as this method's type parameter may represent any subtype of AnyRef, not just Throwable or one of its subclasses. In Scala, exceptions can be caught based on traits they implement, so it may at times make sense to specify a trait that the intercepted exception's class must mix in. If a class instance is passed for a type that could not possibly be used to catch an exception (such as String, for example), this method will complete abruptly with a TestFailedException.

    Also note that the difference between this method and intercept is that this method does not return the expected exception, so it does not let you perform further assertions on that exception. Instead, this method returns Succeeded, which means it can serve as the last statement in an async- or safe-style suite. It also indicates to the reader of the code that nothing further is expected about the thrown exception other than its type. The recommended usage is to use assertThrows by default, intercept only when you need to inspect the caught exception further.

  33. final def execute(testName: String = null, configMap: ConfigMap = ConfigMap.empty, color: Boolean = true, durations: Boolean = false, shortstacks: Boolean = false, fullstacks: Boolean = false, stats: Boolean = false): Unit

    Executes one or more tests in this Suite, printing results to the standard output.

    Executes one or more tests in this Suite, printing results to the standard output.

    This method invokes 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 testName parameter

    If you leave testName at its default value (of null), this method will pass None to the testName parameter of run, and as a result all the tests in this suite will be executed. If you specify a testName, this method will pass Some(testName) to run, 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 to run. If not, the default value of an empty Map 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 to run to print to the standard output in color (via ansi escape characters). If you don't want color output, specify false for color, 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 to run to not print durations for tests and suites to the standard output. If you want durations printed, specify true for durations, like this:

    scala> (new ExampleSuite).execute(durations = true)

    The shortstacks and fullstacks parameters

    If you leave both the shortstacks and fullstacks parameters unspecified, this method will configure the reporter it passes to run 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 shortstacks and fullstacks, you'll get full stack traces.

    The stats parameter

    If you leave the stats parameter unspecified, this method will not fire RunStarting and either RunCompleted or RunAborted events to the reporter it passes to run. If you specify true for stats, this method will fire the run events to the reporter, and the reporter will print the expected test count before the run, and various statistics after, including the number of suites completed and number of tests that succeeded, failed, were ignored or marked pending. Here's how you get the stats:

    scala> (new ExampleSuite).execute(stats = true)

    To summarize, this method will pass to run:

    • testName - None if this method's testName parameter is left at its default value of null, else Some(testName).
    • reporter - a reporter that prints to the standard output
    • stopper - a Stopper whose apply method always returns false
    • filter - a Filter constructed with None for tagsToInclude and Set() for tagsToExclude
    • configMap - the configMap passed to this method
    • distributor - None
    • tracker - a new Tracker

    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 named run, this method would have the same name but different arguments than the main run 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 is null. Normally in Scala the type of testName would be Option[String] and the default value would be None, as it is in this trait's run method. The null 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 type String, as it did in two of the overloaded execute methods prior to 1.5. The other reason is that execute 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. A String type with a null default value lets users type suite.execute("my test name") rather than suite.execute(Some("my test name")), saving several keystrokes.

    The second non-idiomatic feature is that shortstacks and fullstacks are all lower case rather than camel case. This is done to be consistent with the Shell, which also uses those forms. The reason lower case is used in the Shell 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 like shortstacks, fullstacks, and nostats, etc., are designed to be all lower case so they feel more like shell commands than methods.

    Intercept and return an exception that's expected to be thrown by the passed function value.

    Intercept and return an exception that's expected to be thrown by the passed function value. The thrown exception must be an instance of the type specified by the type parameter of this method. This method invokes the passed function. If the function throws an exception that's an instance of the specified type, this method returns that exception. Else, whether the passed function returns normally or completes abruptly with a different exception, this method throws TestFailedException.

    Note that the type specified as this method's type parameter may represent any subtype of AnyRef, not just Throwable or one of its subclasses. In Scala, exceptions can be caught based on traits they implement, so it may at times make sense to specify a trait that the intercepted exception's class must mix in. If a class instance is passed for a type that could not possibly be used to catch an exception (such as String, for example), this method will complete abruptly with a TestFailedException.

    Also note that the difference between this method and assertThrows is that this method returns the expected exception, so it lets you perform further assertions on that exception. By contrast, the assertThrows method returns Succeeded, which means it can serve as the last statement in an async- or safe-style suite. assertThrows also indicates to the reader of the code that nothing further is expected about the thrown exception other than its type. The recommended usage is to use assertThrows by default, intercept only when you need to inspect the caught exception further.

  49. def pending: Assertion with PendingStatement

    Throws TestPendingException to indicate a test is pending.

    Throws TestPendingException to indicate a test is pending.

    A pending test is one that has been given a name but is not yet implemented. The purpose of pending tests is to facilitate a style of testing in which documentation of behavior is sketched out before tests are written to verify that behavior (and often, the before the behavior of the system being tested is itself implemented). Such sketches form a kind of specification of what tests and functionality to implement later.

    To support this style of testing, a test can be given a name that specifies one bit of behavior required by the system being tested. The test can also include some code that sends more information about the behavior to the reporter when the tests run. At the end of the test, it can call method pending, which will cause it to complete abruptly with TestPendingException. Because tests in ScalaTest can be designated as pending with TestPendingException, both the test name and any information sent to the reporter when running the test can appear in the report of a test run. (In other words, the code of a pending test is executed just like any other test.) However, because the test completes abruptly with TestPendingException, the test will be reported as pending, to indicate the actual test, and possibly the functionality it is intended to test, has not yet been implemented.

    Note: This method always completes abruptly with a TestPendingException. Thus it always has a side effect. Methods with side effects are usually invoked with parentheses, as in pending(). This method is defined as a parameterless method, in flagrant contradiction to recommended Scala style, because it forms a kind of DSL for pending tests. It enables tests in suites such as FunSuite or FunSpec to be denoted by placing "(pending)" after the test name, as in:

    test("that style rules are not laws") (pending)

    Readers of the code see "pending" in parentheses, which looks like a little note attached to the test name to indicate it is pending. Whereas "(pending()) looks more like a method call, "(pending)" lets readers stay at a higher level, forgetting how it is implemented and just focusing on the intent of the programmer who wrote the code.

    Execute the passed block of code, and if it completes abruptly, throw TestPendingException, else throw TestFailedException.

    Execute the passed block of code, and if it completes abruptly, throw TestPendingException, else throw TestFailedException.

    This method can be used to temporarily change a failing test into a pending test in such a way that it will automatically turn back into a failing test once the problem originally causing the test to fail has been fixed. At that point, you need only remove the pendingUntilFixed call. In other words, a pendingUntilFixed surrounding a block of code that isn't broken is treated as a test failure. The motivation for this behavior is to encourage people to remove pendingUntilFixed calls when there are no longer needed.

    This method facilitates a style of testing in which tests are written before the code they test. Sometimes you may encounter a test failure that requires more functionality than you want to tackle without writing more tests. In this case you can mark the bit of test code causing the failure with pendingUntilFixed. You can then write more tests and functionality that eventually will get your production code to a point where the original test won't fail anymore. At this point the code block marked with pendingUntilFixed will no longer throw an exception (because the problem has been fixed). This will in turn cause pendingUntilFixed to throw TestFailedException with a detail message explaining you need to go back and remove the pendingUntilFixed call as the problem orginally causing your test code to fail has been fixed.

  52. def run(testName: Option[String], args: Args): Status

    Runs this suite of tests.

    Runs this suite of tests.

    If testName is None, this trait's implementation of this method calls these two methods on this object in this order:

    • runNestedSuites
    • runTests

    If testName is defined, then this trait's implementation of this method calls runTests, but does not call runNestedSuites. This behavior is part of the contract of this method. Subclasses that override run must take care not to call runNestedSuites if testName is defined. (The OneInstancePerTest trait depends on this behavior, for example.)

    Subclasses and subtraits that override this run method can implement them without invoking either the runTests or runNestedSuites methods, which are invoked by this trait's implementation of this method. It is recommended, but not required, that subclasses and subtraits that override run in a way that does not invoke runNestedSuites also override runNestedSuites and make it final. Similarly it is recommended, but not required, that subclasses and subtraits that override run in a way that does not invoke runTests also override runTests (and runTest, which this trait's implementation of runTests calls) and make it final. The implementation of these final methods can either invoke the superclass implementation of the method, or throw an UnsupportedOperationException if appropriate. The reason for this recommendation is that ScalaTest includes several traits that override these methods to allow behavior to be mixed into a Suite. For example, trait BeforeAndAfterEach overrides runTestss. 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.)

If a nested Suite's run method completes abruptly with an exception, this trait's implementation of this method reports that the Suite aborted and attempts to run the next nested Suite. If the passed distributor is defined, this trait's implementation puts each nested Suite into the Distributor contained in the Some, in the order in which the Suites appear in the List returned by nestedSuites, passing in a new Tracker obtained by invoking nextTracker on the Tracker passed to this method.

    Implementations of this method are responsible for ensuring SuiteStarting events are fired to the Reporter before executing any nested Suite, and either SuiteCompleted or SuiteAborted after executing any nested Suite.

    Run zero to many of this Suite's tests.

    This method takes a testName parameter that optionally specifies a test to invoke. If testName is defined, this trait's implementation of this method invokes runTest on this object, passing in:

    • testName - the String value of the testName Option passed to this method
    • reporter - the Reporter passed to this method, or one that wraps and delegates to it
    • stopper - the Stopper passed to this method, or one that wraps and delegates to it
    • configMap - the configMap Map passed to this method, or one that wraps and delegates to it

    This method takes a Filter, which encapsulates an optional Set of tag names that should be included (tagsToInclude) and a Set that should be excluded (tagsToExclude), when deciding which of this Suite's tests to run. If tagsToInclude is None, all tests will be run except those those belonging to tags listed in the tagsToExclude Set. If tagsToInclude is defined, only tests belonging to tags mentioned in the tagsToInclude Set, and not mentioned in the tagsToExcludeSet will be run. However, if testName is defined, tagsToInclude and tagsToExclude are essentially ignored. Only if testName is None will tagsToInclude and tagsToExclude be consulted to determine which of the tests named in the testNames Set should be run. This trait's implementation behaves this way, and it is part of the general contract of this method, so all overridden forms of this method should behave this way as well. For more information on test tags, see the main documentation for this trait and for class Filter. Note that this means that even if a test is marked as ignored, for example a test method in a Suite annotated with org.scalatest.Ignore, if that test name is passed as testName to runTest, it will be invoked despite the Ignore annotation.

    If testName is None, this trait's implementation of this method invokes testNames on this Suite to get a Set of names of tests to potentially run. (A testNames value of None essentially acts as a wildcard that means all tests in this Suite that are selected by tagsToInclude and tagsToExclude should be run.) For each test in the testName Set, in the order they appear in the iterator obtained by invoking the elements method on the Set, this trait's implementation of this method checks whether the test should be run based on the Filter. If so, this implementation invokes runTest, passing in:

    • testName - the String name of the test to run (which will be one of the names in the testNames Set)
    • reporter - the Reporter passed to this method, or one that wraps and delegates to it
    • stopper - the Stopper passed to this method, or one that wraps and delegates to it
    • configMap - the configMap passed to this method, or one that wraps and delegates to it

    If a test is marked with the org.scalatest.Ignore tag, implementations of this method are responsible for ensuring a TestIgnored event is fired for that test and that runTest is not called for that test.

    testName

    an optional name of one test to run. If None, all relevant tests should be run. I.e., None acts like a wildcard that means run all relevant tests in this Suite.

    A string ID for this Suite that is intended to be unique among all suites reported during a run.

    This trait's implementation of this method returns the fully qualified name of this object's class. Each suite reported during a run will commonly be an instance of a different Suite class, and in such cases, this default implementation of this method will suffice. However, in special cases you may need to override this method to ensure it is unique for each reported suite. For example, if you write a Suite subclass that reads in a file whose name is passed to its constructor and dynamically creates a suite of tests based on the information in that file, you will likely need to override this method in your Suite subclass, perhaps by appending the pathname of the file to the fully qualified class name. That way if you run a suite of tests based on a directory full of these files, you'll have unique suite IDs for each reported suite.

    The suite ID is intended to be unique, because ScalaTest does not enforce that it is unique. If it is not unique, then you may not be able to uniquely identify a particular test of a particular suite. This ability is used, for example, to dynamically tag tests as having failed in the previous run when rerunning only failed tests.

    This trait's implementation of this method uses Java reflection to discover any Java annotations attached to its test methods. The fully qualified name of each unique annotation that extends TagAnnotation is considered a tag.

    The styleName lifecycle method has been deprecated and will be removed in a future version of ScalaTest.

    This method was used to support the chosen styles feature, which was deactivated in 3.1.0. The internal modularization of ScalaTest in 3.2.0 will replace chosen styles as the tool to encourage consistency across a project. We do not plan a replacement for styleName.
