 ##### Running tests
 
+Run `yalc publish --push` in the root directory of the gem to ensure the test suites use the exact same js code used in the currenlty developing ReactRails.
+
 `bundle exec appraisal install` to install gems on every gemfile Appraisal contains.
 `rake test` or `bundle exec appraisal rake test` runs everything.
 or run a specific suite using `bundle exec appraisal <appraisal name> rake test`
 - Find appraisal names in [Appraisals](Appraisals)
 - Integration tests run in Headless Chrome which is included in Chrome (59+ linux,OSX | 60+ Windows)
 - ChromeDriver is included with `chromedriver-helper` gem so no need to manually install that 👍
 
+**Note:** If using Ruby 2.7, set `MT_KWARGS_HACK=1` to ensure Minitest runs smoothly.

 ##### Updating the pre-bundled react
 - Update React with `rake react:update`
 It outputs an ironically webpacked couple of files into `lib/assets/react-source/<environment>/react(-server).js` where it will be picked up by `sprockets` in `lib/react/rails/asset_variant.rb`

 LibV8 itself is already [beyond version 7](https://github.com/cowboyd/libv8/releases/tag/v7.3.492.27.1) therefore many serverside issues are caused by old JS engines and fixed by using an up to date one such as [MiniRacer](https://github.com/discourse/mini_racer) or [TheRubyRhino](https://github.com/cowboyd/therubyrhino) on JRuby.
 
 ### HMR
-Hot Module Replacement is [possible with this gem](https://stackoverflow.com/a/54846330/193785) as it does just pass through to Webpacker. Please open an issue to let us know tips and tricks for it to add to the wiki.
