New gem - testing execution of controller action filters with RSpec

Hello everybody,

I published my first gem (rspec-matchers-controller_filters
https://github.com/iridakos/rspec-matchers-controller_filters) for
testing execution of before/around/after filters of controller actions
with
RSpec.

Any feedback is welcome!
