Mocks and stubs can be fragile and come back and bite you when they can get out of sync with your code. One way this can happen is that a method is renamed or you misspell the method name. To avoid this issue you can configure Mocha to disallow stubbing and mocking of non-existent methods. I've come up with two new methods for the cases where you are working with messages implemented with method_missing:

It is interesting to note that this extension of Mocha is possible because of its flexible and clever design. Mocha was recently updated to version 0.9.9. I am grateful to James Mead (Floehopper) for providing this excellent testing library.
