Asserting call counts

Using the times(N) modifier, or its aliases (once, twice, or never) allows you to create call count expectations that will be automatically checked by the test runner.

Note

If you do not provide times modifier. The mock is expected to be called zero or any number of times. In other words, the call count is not asserted.

Ensure fly("forward") gets called exactly three times

flexmock(plane).should_receive("fly").with_args("forward").times(3)

Ensure turn("east") gets called at least twice:

flexmock(plane).should_receive("turn").with_args("east").at_least().twice()

Ensure land("airfield") gets called at most once:

flexmock(plane).should_receive("land").with_args("airfield").at_most().once()

Ensure that crash("boom!") is never called:

flexmock(plane).should_receive("crash").with_args("boom!").never()
