Mockito Spy - stub before calling the constructor

Question

I\'m trying to spy on an Object and I want to stub a method that is called by the constructor before the constructor calls it.
My class looks like that:

Answer 1

1. Use PowerMock.

2. After you've imported the libraries, set it up to manipulate the class you want to mock with the instance method that mustn't be called.

Like so:

@RunWith(PowerMockRunner.class)
@PrepareForTest({, Myclass.class})

3. Suppress the method at the start of your test.

Like so:

suppress(method(Myclass.class, "setup"));

4. Customize the behaviour of your setup() method as desired, in your test.

Like so:

doAnswer(new Answer() {
      @Override
      public Void answer(InvocationOnMock invocation) throws Throwable {
           // code here
           return null;
      }
 }).when(Myclass.class, "setup");
