Using Expected Exceptions in UnitTests
Sometimes, reviewing code, I see misunderstanding of using Expected Exception concept in unit tests.
Let’s consider following test class:
There are two test methods here and only first one is not correct.
When service throws SomeException
, Mockito.verifyZeroInteraction(bar)
is not invoked,
although expected exception is catched and test framework reports test passed.
The Rule of Thumb is:
You may use ExpectedException
only if call of the method under test is the last operator of test method.
