Secrets of Testing Rails 5 apps

" summary

Rails 5 gives concrete testing changes: a new Test Runner invoked via bin/rails test (powered by Minitest 5 plugins) that prints runnable failing lines, supports -f and -b, and enables colored output; generated controller tests use ActionDispatch::IntegrationTest by default (assign/assert_template deprecated and extractable to rails-controller-testing); API tests get request encoders (as: :json) and response parsing via parsed_body; Active Job uses the async adapter in test, test order is randomized, and new helpers like file_fixture reduce boilerplate.
