I'm assuming you're trying to create a wonderful test case, to make sure the specific exception won't get thrown in production mode. A good way is ,in the Sprint Testing and Integration Testing phrases, try to list all potential use cases and ask QA's help. For the cases, use AssertTrue is enough to get all them passed.

If you use JUnit 4, your test method is annotated using @Test. As long as you do not specify an expected attribute, any Exception will cause that test to fail. See the JUnit FAQ for details.

JUnit will say that your function did not do as expected (like when an AssertTrue returns fals, for instance) if it throws an unhandled exception. So, just don't catch it in JUnit and you should be fine.
