Question

Is it possible to fetch/store what arguments were used when using Mockito.when?

For example this pseudo code:

Mockito.when(mock.someMethod(**any string**)).thenReturn(print(** any string **));

print would be:

public void print(String s) {
    System.out.println(s);
}

Which could be used like this:

Person mockPerson = ...

mockPerson.setName("John");

Which would trigger that ‘John’ would be printed to std out.

Maybe a lame example, but I want to “store”/”use” any arguments the mocked-method would have been called with.

Follow-up question: If not, what other testing frameworks can do this.

ArgumentCaptor documentation could be interesting for you.
