MultipleFixtureFlatSpec

trait MultipleFixtureFlatSpec extends FixtureFlatSpec with ConfigMapFixture

A sister trait to org.scalatest.FlatSpec that can pass multiple types of fixture objects into its tests.

This trait behaves similarly to trait org.scalatest.FlatSpec, except that tests may take a fixture object, and unlike a FixtureFlatSpec, different tests may take different types of fixtures. This trait extends FixtureFlatSpec and mixes in ConfigMapFixture, which defines the Fixture type to be the configMap's type (Map[String, Any]) and defines the withFixture method to simply pass the configMap to the test function. To write tests that take fixtures of types other than Fixture (i.e., Map[String, Any]), you can define implicit conversions from a function of type (<the fixture type>) => Unit to a function of type (FixtureParam) => Unit. Each implicit conversion method serves as the with-fixture method for that type.

Subclasses of this trait must, therefore, do two things differently from a plain old org.scalatest.FlatSpec:

Here's an example that has two fixture types, String and List[Int]:

import org.scalatest.fixture.MultipleFixtureFlatSpec
class MyFlatSpec extends MultipleFixtureFlatSpec {
  // The "with-fixture" method for tests that take a String fixture
  implicit def withStringFixture(testFunction: String => Unit): FixtureParam => Unit =
    testFunction("howdy")
  // The "with-fixture" method for tests that take a List[Int] fixture
  implicit def withListFixture(testFunction: List[Int] => Unit): FixtureParam => Unit =
    configMap => testFunction(List(configMap.size))
  // A test that takes a String fixture
  it should "take a string fixture" in { (s: String) =>
    assert(s === "howdy")
  }
  // A test that takes a List[Int] fixture
  it should "take a list fixture" in { (list: List[Int]) =>
    assert(list.size === 1)
  }
  // A test that takes no fixture
  it should "take no fixture" in { () =>
    assert(1 === 1)
  }
}

The first method in this class, withStringFixture, is the implicit conversion function for tests that take a fixture of type String. In this contrived example, the hard-coded string "howdy" is passed into the test:

implicit def withStringFixture(testFunction: String => Unit): FixtureParam => Unit =
  testFunction("howdy")

Although the result type of this implicit conversion method is FixtureParam => Unit, if a fixture doesn't need anything from the configMap, you can leave off the configMap => at the beginning of the result function. The reason this works is that MultipleFixtureFlatSpec inherits an implicit conversion from a by-name parameter to FixtureParam => Unit from supertrait FixtureFlatSpec. This implicit conversion is used to enable tests that take no fixture (such as the one named takes no fixture in this example) to be included in the same class as tests that take type Fixture. That same implicit conversion is used here to allow you to leave off the configMap => except when you actually need something from the configMap. By leaving it off, you indicte to readers of the code that this fixture doesn't require anything from the configMap.

The next method in this class, withListFixture, is the implicit conversion function for tests that take a fixture of type List[Int]. In this contrived example, a List[Int] that contains one element, the size of the configMap, is passed to the test function. Because the fixture uses the configMap, it has an explicit configMap => parameter at the beginning of the result. (Remember, the Fixture type is defined to be Map[String, Any], the type of the configMap, in supertrait ConfigMapFixture.

Following the implicit conversion methods are the test declarations. One test is written to take the String fixture:

it should "take a string fixture" in { (s: String) =>
  assert(s === "howdy")
}

What happens at compile time is that because the Fixture type is Map[String, Any], the test method should be passed a function from type (Map[String, Any]) => Unit, or using the type alias, (FixtureParam) => Unit. Passing a function of type String => Unit as is attempted here is a type error. Thus the compiler will look around for an implicit conversion that will fix the type error, and will find the withStringFixture method. Because this is the only implicit conversion that fixes the type error, it will apply it, effectively generating this code:

// after the implicit withStringFixture method is applied by the compiler
it should "take a string fixture" in {
  withStringFixture { (s: String) =>
    assert(s === "howdy")
  }
}

After passing the (String) => Unit function to withStringFixture, the result will be of type (FixtureParam) => Unit, which the test method expects.

The next test is written to take the List[Int] fixture:

it should "take a list fixture" in { (list: List[Int]) =>
  assert(list.size === 1)
}

The compiler will apply the withListFixture implicit conversion in this case, effectively generating the following code:

it should "take a list fixture" in {
  withListFixture { (list: List[Int]) =>
    assert(list.size === 1)
  }
}

Note that in a FixtureFlatSpec, you need to specify the type of the fixture explicitly so the compiler knows the type to convert from. So you must, for example, write:

it should "take a list fixture" in { (list: List[Int]) =>
  assert(list.size === 1)
}

The following attempt will fail to compile:

// won't compile, because list is inferred to be of type FixtureParam
it should "take a list fixture" in { list =>
  assert(list.size === 1)
}

    This method is used to cast the receiver object to be of type T0.

    Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested typed.

  16. implicit def convertToEqualizer ( left : Any ) : Equalizer

    Implicit conversion from Any to Equalizer, used to enable assertions with === comparisons.

    Implicit conversion from Any to Equalizer, used to enable assertions with === comparisons.

    For more information on this mechanism, see the documentation for </code>Equalizer</code>.

    Because trait Suite mixes in Assertions, this implicit conversion will always be available by default in ScalaTest Suites. This is the only implicit conversion that is in scope by default in every ScalaTest Suite. Other implicit conversions offered by ScalaTest, such as those that support the matchers DSL or invokePrivate, must be explicitly invited into your test code, either by mixing in a trait or importing the members of its companion object. The reason ScalaTest requires you to invite in implicit conversions (with the exception of the implicit conversion for === operator) is because if one of ScalaTest's implicit conversions clashes with an implicit conversion used in the code you are trying to test, your program won't compile. Thus there is a chance that if you are ever trying to use a library or test some code that also offers an implicit conversion involving a === operator, you could run into the problem of a compiler error due to an ambiguous implicit conversion. If that happens, you can turn off the implicit conversion offered by this convertToEqualizer method simply by overriding the method in your Suite subclass, but not marking it as implicit:

    // In your Suite subclass
override def convertToEqualizer(left: Any) = new Equalizer(left)

  22. def eq ( arg0 : AnyRef ) : Boolean

    This method is used to test whether the argument (arg0) is a reference to the receiver object (this).

    This method is used to test whether the argument (arg0) is a reference to the receiver object (this).

    The eq method implements an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation] on non-null instances of AnyRef: * It is reflexive: for any non-null instance x of type AnyRef, x.eq(x) returns true. * It is symmetric: for any non-null instances x and y of type AnyRef, x.eq(y) returns true if and only if y.eq(x) returns true. * It is transitive: for any non-null instances x, y, and z of type AnyRef if x.eq(y) returns true and y.eq(z) returns true, then x.eq(z) returns true.

    Additionally, the eq method has three other properties. * It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false. * For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false. * null.eq(null) returns true.

    When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

    arg0

    the object to compare against this object for reference equality.

    returns

    true if the argument is a reference to the receiver object; false otherwise.

    attributes: final
    definition classes: AnyRef

  23. def equals ( arg0 : Any ) : Boolean

    This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.

    This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.

    The default implementations of this method is an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation]: * It is reflexive: for any instance x of type Any, x.equals(x) should return true. * It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true. * It is transitive: for any instances x, y, and z of type AnyRef if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

    If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is often necessary to override hashCode to ensure that objects that are "equal" (o1.equals(o2) returns true) hash to the same scala.Int (o1.hashCode.equals(o2.hashCode)).

    arg0

    the object to compare against this object for equality.

    returns

    true if the receiver object is equivalent to the argument; false otherwise.

    Executes this Suite, printing results to the standard output.

    This method implementation calls run on this Suite, passing in:

    • testName - None
    • 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 - an empty Map[String, Any]
    • distributor - None
    • tracker - a new Tracker

    This method serves as a convenient way to execute a Suite, especially from within the Scala interpreter.

    Note: In ScalaTest, the terms "execute" and "run" basically mean the same thing and can be used interchangably. The reason this convenience method and its three overloaded forms aren't named run is because junit.framework.TestCase declares a run method that takes no arguments but returns a junit.framework.TestResult. That run method would not overload with this method if it were named run, because it would have the same parameters but a different return type than the one defined in TestCase. To facilitate integration with JUnit 3, therefore, these convenience "run" methods are named execute. In particular, this allows trait org.scalatest.junit.JUnit3Suite to extend both org.scalatest.Suite and junit.framework.TestCase, which enables the creating of classes that can be run with either ScalaTest or JUnit 3.

    Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

    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.

    f

    Note that the test result of the test is modulo Scala's erasure semantics. Therefore the expression 1.isInstanceOf[String] will return false, while the expression List(1).isInstanceOf[List[String]] will return true. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested typed.

  48. def pending : PendingNothing

    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 Spec 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.

    definition classes: Suite

  49. def pendingUntilFixed ( f : ⇒ Unit ) : Unit

    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.

  50. def run ( testName : Option[String] , reporter : Reporter , stopper : Stopper , filter : Filter , configMap : Map[String, Any] , distributor : Option[Distributor] , tracker : Tracker ) : Unit

    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(report, stopper, tagsToInclude, tagsToExclude, configMap, distributor)
    • runTests(testName, report, stopper, tagsToInclude, tagsToExclude, configMap)

    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 the passed distributor is None, this trait's implementation of this method invokes run on each nested Suite in the List obtained by invoking nestedSuites. 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.

    This method takes a testName parameter that optionally specifies a test to invoke. If testName is Some, 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 passed to this method, or one that wraps and delegates to it

    This method takes a 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 execute. If tagsToInclude is empty, all tests will be executed except those those belonging to tags listed in the tagsToExclude Set. If tagsToInclude is non-empty, only tests belonging to tags mentioned in tagsToInclude, and not mentioned in tagsToExclude will be executed. However, if testName is Some, 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. For more information on trait tags, see the main documentation for this trait.

    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 execute. (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 executed.) 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 tagsToInclude and tagsToExclude Sets. 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

  66. def withFixture ( test : NoArgTest ) : Unit

    Run the passed test function in the context of a fixture established by this method.

    Run the passed test function in the context of a fixture established by this method.

    This method should set up the fixture needed by the tests of the current suite, invoke the test function, and if needed, perform any clean up needed after the test completes. Because the NoArgTest function passed to this method takes no parameters, preparing the fixture will require side effects, such as reassigning instance vars in this Suite or initializing a globally accessible external database. If you want to avoid reassigning instance vars you can use FixtureSuite.

    This trait's implementation of runTest invokes this method for each test, passing in a NoArgTest whose apply method will execute the code of the test.

    This trait's implementation of this method simply invokes the passed NoArgTest function.
