ruby on rails - Adding minitests/reporters to test_helper.rb - error message -

-

so bit beyond knowledge. added minitests/reporters test_helper.rb doing following :

i installed minitest reporters gem : gem install minitest-reporters , added require in test_helper.rb:

require "minitest/reporters" minitest::reporters.

when run tests, here : should reinstall gems?

here did , worked :

1- added test_helper.rb following : require "minitest/reporters" minitest::reporters.use!

2- added gemfile following : gem 'minitest', group: :test gem 'minitest-reporters', group: :test

3- run rails test
