Defines type Fixture to be Conductor.
Creates a new Conductor, passes the Conductor to the
specified test function, and ensures that conduct gets invoked
on the Conductor.
Creates a new Conductor, passes the Conductor to the
specified test function, and ensures that conduct gets invoked
on the Conductor.
After the test function returns (so long as it returns normally and doesn't
complete abruptly with an exception), this method will determine whether the
conduct method has already been called (by invoking
conductingHasBegun on the Conductor). If not,
this method will invoke conduct to ensure that the
multi-threaded scenario is actually conducted.
Trait that can pass a new
Conductorfixture into tests.Here's an example of the use of this trait to test the
ArrayBlockingQueueclass fromjava.util.concurrent:import org.scalatest.fixture.FixtureFunSuite import org.scalatest.concurrent.ConductorFixture import org.scalatest.matchers.ShouldMatchers import java.util.concurrent.ArrayBlockingQueue class ArrayBlockingQueueSuite extends FixtureFunSuite with ConductorFixture with ShouldMatchers { test("calling put on a full queue blocks the producer thread") { conductor => import conductor._ val buf = new ArrayBlockingQueue[Int](1) thread("producer") { buf put 42 buf put 17 beat should be (1) } thread("consumer") { waitForBeat(1) buf.take should be (42) buf.take should be (17) } whenFinished { buf should be ('empty) } } test("calling take on an empty queue blocks the consumer thread") { conductor => import conductor._ val buf = new ArrayBlockingQueue[Int](1) thread("producer") { waitForBeat(1) buf put 42 buf put 17 } thread("consumer") { buf.take should be (42) buf.take should be (17) beat should be (1) } whenFinished { buf should be ('empty) } } }For an explanation of how these tests work, see the documentation for
Conductor.
