 ### BUNDLE_GEMFILE
 We can use this variable to tell bundler what Gemfile it should use (instead of the one in the current directory).

When you send us a pull request, it may happen that the test suite breaks using some of them. If that's the case, you can simulate the same environment using the `BUNDLE_GEMFILE` variable.
