JUnit @Rule ExpectedException marked as failure


In the Clover HTML output, Clover marks JUnit tests that use the new JUnit @Rule ExpectedException to check for exceptions as failures, even though the test actually passes. I found this on the documentation: http://confluence.atlassian.com/display/CLOVER/Unit+Test+Results+and+Per-Test+Coverage however, the comment on it is not clear to me:

Clover does its best to record your test results in the Clover database. In some instances however, Clover can not always do so. Although unit tests using@Test(expected=Exception.class) annotations will be marked as passed, more novel JUnit constructs such as rules may not be recognized and Clover will flag those tests as failed when in fact they passed. To integrate these test results into your Clover reports follow these steps:

Does this mean that this is a known issue that can/will never be fixed, or will there eventually be some fix?

Yes, this is a known issue. Unfortunately it's fairly infeasible for us to fix hence you will need to follow the workaround to get correct test results integrated into your Clover report.

While it may be infeasible to fix all @Rule classes, shouldn't it be possible to develop a solution for something as common and helpful as the ExpectedException rule?

I'm suffering from the same problem. ExpectedException rule is ignored and tests marked as failed even though they pass. I don't want to change 350 unit test . I'm trying to find a workaround but no success so far. I'm using Maven, please help!

Note: I'd be satisfied with just being able to say "includeFailedTestCoverage" in maven plugin.

Dear, Is this issue still existing or has been resolved?

I am also facing this issue!!

Is there any update on this issue?

As an option to workaround this is to change all tests from @Rule to @Test(expected=MyException.class)? Is there any other way to approach it?

Hi Oleksii,

Can't say if there are any solutions, but I'd like to note that migrating your tests from `ExpectedException` rule to `expected` parameter of `Test` annotation is not a good one: http://errorprone.info/bugpattern/TestExceptionChecker
