class TestKit extends AnyRef

Java API: Test kit for testing actors. Inheriting from this class enables reception of replies from actors, which are queued by an internal actor and can be examined using the expectMsg... methods. Assertions and bounds concerning timing are available in the form of Within blocks.

Beware of two points:

  • the ActorSystem passed into the constructor needs to be shutdown, otherwise thread pools and memory will be leaked - this trait is not thread-safe (only one actor with one queue, one stack of Within blocks); take care not to run tests within a single test class instance in parallel.
  • It should be noted that for CI servers and the like all maximum Durations are scaled using the dilated method, which uses the TestKitExtension.Settings.TestTimeFactor settable via akka.conf entry "akka.test.timefactor".

    Receive one message from the test actor and assert that it equals one of the given objects. Wait time is bounded by the given duration, with an AssertionFailure being thrown in case of timeout.

  20. def receiveWhile[T](max: Duration, idle: Duration, messages: Int, f: Function[AnyRef, T]): List[T]

    Receive a series of messages until one does not match the given partial function or the idle timeout is met (disabled by default) or the overall maximum duration is elapsed or expected messages count is reached.

    Receive a series of messages until one does not match the given partial function or the idle timeout is met (disabled by default) or the overall maximum duration is elapsed or expected messages count is reached. Returns the sequence of messages.

    Note that it is not an error to hit the max duration in this case.

    One possible use of this method is for testing whether messages of certain characteristics are generated at a certain rate:

    Execute code block while bounding its execution time between min and max. within blocks may be nested. All methods in this trait which take maximum wait times are available in a version which implicitly uses the remaining time governed by the innermost enclosing within block.

    Note that the timeout is scaled using Duration.dilated, which uses the configuration entry "akka.test.timefactor", while the min Duration is not.
