This only works if both the original and new values are modules (or classes). privacy statement. to rspec I've got an instance double of a class and I want to stub two calls to the same method and return different values based on different arguments. have_received().with() is unable to work properly when passed arguments are mutated after the spy records the received message. While in the second test, you are traveling to the future, when the item already expired. Alternatively, this method also accepts a block and freezes the time inside the block. That's it. Returns to the original time, by removing the stubs added by travel and travel_to. Is there a discussion one can read somewhere about ceasing development of any instance functionality? Unlike travel, this method allows you to time travel to both future and past by specifying the date_or_time. In all other ways it behaves like a double.
