RSpec Mocks
rspec-mocks provides a test-double framework for rspec including support
for method stubs, fakes, and message expectations.
Documentation
The Cucumber features are the
most comprehensive and up-to-date docs for end-users.
The RDoc provides additional
information for contributors and/or extenders.
All of the documentation is open source and a work in progress. If you find it
lacking or confusing, you can help improve it by submitting requests and
patches to the rspec-mocks issue
tracker.
