Yes, these tests are amenable to TestNG's `assertThrows` method. That might be all you need; we generally aren't too concerned about the exact content and formatting of the exception's message. However, if you want to make additional assertions over the thrown exception, it can be obtained using `expectThrows` instead of `assertThrows`.
