Mockito.any() pass Interface with Generics

is it possible to pass the type of an interface with generics?

The interface:

public interface AsyncCallback<T>

In my test method:

Mockito.any(AsyncCallback.class)

Putting <ResponseX> behind or for .class didnt work.

Solution 1:

There is a type-safe way: use ArgumentMatchers.any() and qualify it with the type:

ArgumentMatchers.<AsyncCallback<ResponseX>>any()

Solution 2:

Using Java 8, you can simply use any() (assuming static import) without argument or type parameter because of enhanced type inference. The compiler now knows from the target type (the type of the method argument) that you actually mean Matchers.<AsyncCallback<ResponseX>>any(), which is the pre-Java 8 solution.

Solution 3:

I had to adopt the following mechamism to allow for generics:

import static org.mockito.Matchers.any;
List<String> list = any();
when(callMyMethod.getResult(list)).thenReturn(myResultString);

Hope this helps someone.
