Be careful with stub! in RSpec

First of all, you should be careful with any call to stub.

You probably want to use stub just to simulate a behavior, one that you don’t want to test in your current test.

For example: You may want to use stub with a remote service, an API call.

Also, the method is stub not stub! (at least in RSpec 2.6.0)

 
This will not work but will not fail.

This is what you are looking for.

I don’t know exactly why stub! doesn’t fail, but it wasn’t doing what I was expecting (to actually stub that method and return the mock object I wanted)
