Can Mockito stub a method without regard to the argument?

Question

I\'m trying to test some legacy code, using Mockito.

I want to stub a FooDao that is used in production as follows:

foo = fooDao.getBar(         


        

Answer 1

when(
  fooDao.getBar(
    any(Bazoo.class)
  )
).thenReturn(myFoo);

or (to avoid nulls):

when(
  fooDao.getBar(
    (Bazoo)notNull()
  )
).thenReturn(myFoo);

Don't forget to import matchers (many others are available):

For Mockito 2.1.0 and newer:

import static org.mockito.ArgumentMatchers.*;

For older versions:

import static org.mockito.Matchers.*;
