Mockito中通用方法的ArgumentCaptor

Question

I have an object that I've mocked. This object has the following method:

<R, M extends SomeAbstractClass<R>> List<R> execute(List<M> list)

And there are two calls for this method:

execute(List<A>);
execute(List<B>);

where class A extends SomeAbstractClass<String> and B extends SomeAbstractClass<Void> .

Is there any way to use ArgumentCaptor for this case? I want to do something like this:

verify(..., times(3)).execute(argumentCaptor.capture())

I think (but not sure) this problem can't be solved since A and B doesn't have common ancestor which extends SomeAbstractClass<R> .

Anyway, thank you for any suggestions.

Answer 1

I've found the solution. If anybody interested we can use the following syntax for ArgumentCaptor:

ArgumentCaptor<List<? extends SomeAbstractClass>>
