What are the pros and cons of rspec mocking versus other mocking frameworks?
I have seen a lot of outdated podcasts that mention mocha as a gem I would want to install because it does mocking better then rspec. I have a feeling that the rspec developers have caught on to this and have improved their mocking since then. However, in the default spec_helper.rb file I see some commented out code stubs for three mocking frameworks
mocha flexmock rr Upvote to anyone who can give me a decent answer as far as pros and cons on at least one of these frameworks versus rspec 's own mocking framework.
I'll accept an answer if you can give me a break down on all three versus rpsec
Really, it's just a matter of taste. Take a look at the syntax and play around with the mocking frameworks to see what suits you best. Of course, it's quickest and easiest to roll with RSpec's built-in mocking. And, as you mentioned, the developers of RSpec have taken cues from the other frameworks... You'll find a lot of similarities between them.
This question's been asked before: see the details there to get an idea of some of the differences (at least between RSpec::Mock and Mocha).
We were using the built-in rspec mocking, until recently when we switched to mocha. My colleague wrote up a blog post about the gotchas and a bit about the reasoning:

Basically, we wanted mocha's any_instance method, which is useful if you can't get to the instance you want to mock. Not a huge advantage, but enough to make it worth our while.
