JUnit3Suite

class JUnit3Suite extends TestCase with Suite with AssertionsForJUnit

A Suite that is also a junit.framework.TestCase.

A JUnit3Suite may be run by either JUnit 3 (such as JUnit 3.8) or ScalaTest's runner. You write it the way you write a JUnit 3 TestCase. Tests are methods that start with test, take no parameters, and have a Unit return type. You manage fixtures with methods setUp and tearDown. Here's an example:

import org.scalatest.junit.JUnit3Suite
import scala.collection.mutable.ListBuffer

class BlastFromThePastSuite extends JUnit3Suite {

  var sb: StringBuilder = _
  var lb: ListBuffer[String] = _

  override def setUp() {
    sb = new StringBuilder("ScalaTest is ")
    lb = new ListBuffer[String]
  }

  def testEasy() { // Uses JUnit-style assertions
    sb.append("easy!")
    assertEquals("ScalaTest is easy!", sb.toString)
    assertTrue(lb.isEmpty)
    lb += "sweet"
  }

  def testFun() { // Uses ScalaTest assertions
    sb.append("fun!")
    assert(sb.toString === "ScalaTest is fun!")
    assert(lb.isEmpty)
  }
}

You can use either JUnit's assertions, inherited from TestCase, or ScalaTest's, inherited from AssertionsForJUnit. You can also mix in ShouldMatchersForJUnit or MustMatchersForJUnit if you want to use ScalaTests's matchers DSL. Here's an example:

import org.scalatest.junit.JUnit3Suite
import org.scalatest.junit.MustMatchersForJUnit
import scala.collection.mutable.ListBuffer

class BlastFromThePastSuite extends JUnit3Suite with MustMatchersForJUnit {

  var stringBuilder: StringBuilder = _
  var listBuffer: ListBuffer[String] = _

  override def setUp() {
    stringBuilder = new StringBuilder("ScalaTest is ")
    listBuffer = new ListBuffer[String]
  }

  def testEasy() {
    stringBuilder.append("easy!")
    stringBuilder.toString must be ("ScalaTest is easy!")
    listBuffer must be ('empty)
    listBuffer += "sweet"
  }

  def testFun() {
    stringBuilder.append("fun!")
    stringBuilder.toString must be ("ScalaTest is fun!")
    listBuffer must be ('empty)
  }
}

The reason you would ordinarily want to mix in MustMatchersForJUnit or ShouldMatchersForJUnit rather than MustMatchers or ShouldMatchers is that MustMatchersForJUnit and ShouldMatchersForJUnit throw junit.framework.AssertionFailedErrors, which JUnit 3 will report as failures, not errors.

When writing JUnit 3 tests in Scala, you should keep in mind that JUnit 3 will not run tests that have a return type other than Unit. Thus it is best to leave off the equals sign before the curly braces of the body of the test, like this:

def testGoodIdea() { // result type will be Unit
  // ...
}

Instead of this:

def testBadIdea() = { // result type will be inferred
  // ...
}

If the testBadIdea method ends in an expression that has a result type other than Unit, the Scala compiler will infer a result type to the testBadIdea method to be the same non-Unit type. As a "result," JUnit 3 will not discover or run the testBadIdea method at all.

  12. 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 Equalizer.

    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)

    left

    the object whose type to convert to Equalizer.

  17. def execute (testName: String = null, configMap: Map[String, Any] = Map(), 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()

    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. 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.

  35. 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 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.

  36. 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.

  37. 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.)

    Returns the set of test names that will be executed by JUnit when run is invoked on an instance of this class, or the instance is passed directly to JUnit for running.

    The iterator obtained by invoking elements on this returned Set will produce the test names in their natural order, as determined by String's compareTo method. Nevertheless, this method is not consulted by JUnit when it runs the tests, and JUnit may run the tests in any order.

  57. def withClue [T] (clue: Any)(fun: ⇒ T): T

    Executes the block of code passed as the second parameter, and, if it completes abruptly with a ModifiableMessage exception, prepends the "clue" string passed as the first parameter to the beginning of the detail message of that thrown exception, then rethrows it.

    Executes the block of code passed as the second parameter, and, if it completes abruptly with a ModifiableMessage exception, prepends the "clue" string passed as the first parameter to the beginning of the detail message of that thrown exception, then rethrows it. If clue does not end in a white space character, one space will be added between it and the existing detail message (unless the detail message is not defined).

    This method allows you to add more information about what went wrong that will be reported when a test fails. Here's an example:

    withClue("(Employee's name was: " + employee.name + ")") {
  intercept[IllegalArgumentException] {
    employee.getTask(-1)
  }
}

    If an invocation of intercept completed abruptly with an exception, the resulting message would be something like:

    (Employee's name was Bob Jones) Expected IllegalArgumentException to be thrown, but no exception was thrown
