Can Mockito capture arguments of a method called multiple times?

I think it should be

verify(mockBar, times(2)).doSomething(...)

Sample from mockito javadoc:

ArgumentCaptor<Person> peopleCaptor = ArgumentCaptor.forClass(Person.class);
verify(mock, times(2)).doSomething(peopleCaptor.capture());

List<Person> capturedPeople = peopleCaptor.getAllValues();
assertEquals("John", capturedPeople.get(0).getName());
assertEquals("Jane", capturedPeople.get(1).getName());

Since Mockito 2.0 there's also possibility to use static method Matchers.argThat(ArgumentMatcher). With the help of Java 8 it is now much cleaner and more readable to write:

verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("OneSurname")));
verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("AnotherSurname")));

If you're tied to lower Java version there's also not-that-bad:

verify(mockBar).doSth(argThat(new ArgumentMatcher<Employee>() {
        @Override
        public boolean matches(Object emp) {
            return ((Employee) emp).getSurname().equals("SomeSurname");
        }
    }));

Of course none of those can verify order of calls - for which you should use InOrder :

InOrder inOrder = inOrder(mockBar);

inOrder.verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("FirstSurname")));
inOrder.verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("SecondSurname")));

Please take a look at mockito-java8 project which makes possible to make calls such as:

verify(mockBar).doSth(assertArg(arg -> assertThat(arg.getSurname()).isEqualTo("Surname")));
