Example 1 with JUnitExceptionHandler

use of org.eclipse.scout.rt.testing.platform.runner.JUnitExceptionHandler in project scout.rt by eclipse.

the class FormStoredWithVetoTest method assertHandledVetoException.

private void assertHandledVetoException() {
    // Ensure 'JUnitExceptionHandler' to be installed.
    JUnitExceptionHandler exceptionHandler = BEANS.get(JUnitExceptionHandler.class);
    assertTrue(String.format("this test expects 'JUnitExceptionHandler' to be installed [actual=%s]", exceptionHandler), exceptionHandler instanceof JUnitExceptionHandler);

        exceptionHandler.throwOnError();
        fail("VetoException excepted to be handled in 'JUnitExceptionHandler'");

Example 2 with JUnitExceptionHandler

use of org.eclipse.scout.rt.testing.platform.runner.JUnitExceptionHandler in project scout.rt by eclipse.

the class BlockingTestUtility method runBlockingAction.

/**
 * Helper method to test code which will enter a blocking condition.
 * <p>
 * If <code>runnableOnceBlocked</code> throws an exception, it is given to {@link JUnitExceptionHandler} to make the
 * JUnit test fail.
 *
 * @param runnableGettingBlocked
 *          {@code IRunnable} that will enter a blocking condition.
 * @param runnableOnceBlocked
 *          {@code IRunnable} to be executed once the 'runnableGettingBlocked' enters a blocking condition.
 * @param awaitBackgroundJobs
 *          true waits for background jobs running in the same session to complete before runnableOnceBlocked is
 *          called
