类 RunListener

  • 直接已知子类:
    TextListener
    public class RunListener
extends Object
    Register an instance of this class with RunNotifier to be notified of events that occur during a test run. All of the methods in this class are abstract and have no implementation; override one or more methods to receive events.

    For example, suppose you have a Cowbell class that you want to make a noise whenever a test fails. You could write: 

     public class RingingListener extends RunListener {
    public void testFailure(Failure failure) {
       Cowbell.ring();
    }
 }

    To invoke your listener, you need to run your tests through JUnitCore. 

     public void main(String... args) {
    JUnitCore core= new JUnitCore();
    core.addListener(new RingingListener());
    core.run(MyTestClass.class);
 }

    If a listener throws an exception for a test event, the other listeners will have their testFailure(Failure) called with a Description of Description.TEST_MECHANISM to indicate the failure.

    By default, JUnit will synchronize calls to your listener. If your listener is thread-safe and you want to allow JUnit to call your listener from multiple threads when tests are run in parallel, you can annotate your test class with RunListener.ThreadSafe.

    Listener methods will be called from the same thread as is running the test, unless otherwise indicated by the method Javadoc

      • testRunStarted

        public void testRunStarted​(Description description)
                    throws Exception
        Called before any tests have been run. This may be called on an arbitrary thread.
        参数:
        description - describes the tests to be run
        抛出:
        Exception

      • testRunFinished

        public void testRunFinished​(Result result)
                     throws Exception
        Called when all tests have finished. This may be called on an arbitrary thread.
        参数:
        result - the summary of the test run, including all the tests that failed
        抛出:
        Exception

      • testStarted

        public void testStarted​(Description description)
                 throws Exception
        Called when an atomic test is about to be started.
        参数:
        description - the description of the test that is about to be run (generally a class and method name)
        抛出:
        Exception

      • testFinished

        public void testFinished​(Description description)
                  throws Exception
        Called when an atomic test has finished, whether the test succeeds or fails.
        参数:
        description - the description of the test that just ran
        抛出:
        Exception

      • testFailure

        public void testFailure​(Failure failure)
                 throws Exception
        Called when an atomic test fails, or when a listener throws an exception.

        In the case of a failure of an atomic test, this method will be called with the same Description passed to testStarted(Description), from the same thread that called testStarted(Description).

        In the case of a listener throwing an exception, this will be called with a Description of Description.TEST_MECHANISM, and may be called on an arbitrary thread.

        参数:
        failure - describes the test that failed and the exception that was thrown
        抛出:
        Exception

      • testIgnored

        public void testIgnored​(Description description)
                 throws Exception
        Called when a test will not be run, generally because a test method is annotated with Ignore.
        参数:
        description - describes the test that will not be run
        抛出:
        Exception
