Comparison between Mockito vs JMockit - why is Mockito voted better than JMockit? [closed]

Answer 1

I worked with both Mockito and JMockit, and my experience with them is:

• Mockito:

  • implicit mocking (-> better usability, but has the danger of failing to detect not-allowed method calls on mocks)
  • explicit verification

• EasyMock:

  • explict mocking
  • implicit verification

• JMockit:

  • supports both

• Besides, other benefits of JMockit:

  • if you're mocking static methods/constructors etc (such as extending a very old legacy code base without UT), you'll have two choices: 1) Mockito/EasyMock with Powermock extension or 2) Jmockit
  • built-in coverage report

I personally prefer JMockit, which I think is more feature rich and flexible, but requires a little bit steeper learning curve. There're usually multiple ways to achieve the same mocking effect, and requires more care when designing the mocks.
