Run your test files automatically on your source file save.
How it works?
While saving any application app/models/{your_model}.rb file it will look for it's corresponding test file, depends on test framework you use it could be either: spec/models/{your_model}_spec.rb(RSpec) or test/models/{your_model}_test.rb(Minitest).
The results of the test command will be displayed in the Rails Test Runner terminal.
Supports:
RSpec
Minitest
