Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/35792 This Diff fixes a problem we have when running Ruby tests. The previous approach was monkey-patching the Ruby File and Dir classes to override some behaviours we needed during tests. However, these classes are also used by the test runners to properly read and run the tests, therefore when the tests were failing, the stream weren't closed properly and we received the wrong errors. This problem was also preventing us from adopting other Ruby tools like SimpleCov to compute code coverage. ## Changelog: [internal] - refactor Ruby tests not to monkey patch Dir and File Reviewed By: dmytrorykun Differential Revision: D42414717 fbshipit-source-id: 879b9928da1a083ebf9c81b1f510eaa039376042
