Invoke the tested method , which satisfies the second expectation. Expects a long argument greater than or equal to the given value. Another less desirable solution might be to 'capture' the method instead of 'expecting' it, then the captured argument would have to have a way to call/trigger it .

The failure occurs immediately at the first method call exceeding the limit: If there are too few calls, verify(mock) throws an AssertionError: For specifying return values, we wrap the expected call in expect(T value) and specify the return value with the method andReturn(Object returnValue) on the object returned by expect(T value). Mocks are injected to any field in any @TestSubject that is of compatible type. For We have a RecordService class that can be used to save Record data in a backend database.
