## Contributing Install [bundler](http://gembundler.com/) and use it to install all the development dependencies: ```console gem install bundler bundle install ``` You should be able to run the tests now: ```console bundle exec rake ``` VCR uses [RSpec](http://github.com/rspec/rspec) for unit tests. The specs are written in a very "focused" style, where each spec is concerned only with exercising the object under test, using mocks as necessary. You can run the specs using `rake spec`. [Cucumber](http://cukes.info/) is used for end-to-end full stack integration tests that also function as VCR's documentation. ## Problems running bundle install? If you get an error while running `bundle install`, it may be one of the "extras" gems which are not required for development. Try installing it without these gems. ```console bundle install --without extras ```
