Junit : add handling logic when exception is not expected

I am trying to print the stack trace of the exception.

However, for negative test case, only the unexpected exception is printed.

I am using the @Rule ExpectedException to do the exception detecti开发者_JAVA技巧on.

I don't know how to add handling logic in case an unexpected exception is thrown.

@Rule
public ExpectedException thrown = ExpectedException.none();

@Test
public void myTest() throws Exception {
    thrown.expect(MyException.class);
    thrown.expectMessage("expected message");
}

Can't you simply catch the exception within your test method, and then print the stack trace? (and then even rethrow it if you want).

Did you try implementing WatchmanTest.failed?

Franziga, you might try catch-exception to satisfy your theoretical interest:

@Test
public void myTest() throws Exception {

    catchException(obj).doSomethingExceptional();
    log(caughtException());
    assertTrue(caughtException() instanceof MyException.class);
    assertEquals("expected message", caughtException().getMessage());

}
