rspec-rails development

This documentation is meant for folks contributing the rspec-rails project itself.


rspec-rails lives in a complicated ecosystem. We run our specs against multiple Rails and Ruby versions.


By default, rspec-rails' test suite will run against the latest stable version of Rails.

Running Tests

bundle install --binstubs


If you receive an error from bundler where constraints cannot be satisfied for Rails, try removing Gemfile.lock (rm Gemfile.lock) and running bundle install --binstubs again.

This can happen if the Gemfile.lock was generated for a different version of Rails than you are trying to use now.

Changing Rails Version

To run the specs against a different version of Rails, use the thor command:

bin/thor version:use 3.2.13
