 If you have a Rails Engine and want to test it, the suggested approach is a small dummy application that loads up a Rails application with your engine loaded. This dummy application is usually checked into source control and maintained with the application. This works great, until you want to test:
 
  - different versions of Ruby (e.g. MRI and JRuby)
- - different versions of Rails (Rails 5.0, 6.0)
+ - different versions of Rails (Rails 6.1, 7.1)
  - different deployment environments (with and without devise, etc)
 
 where each scenario may involve different configurations, Gemfiles, etc.
