Show minitest options in test runner help Since #29572, minitest options are available but are no longer showed in help. This fixed to show minitest option in help as with Rails 5.1.2. **before** ``` ./bin/rails t --help You can run a single test by appending a line number to a filename: bin/rails test test/models/user_test.rb:27 You can run multiple files and directories at the same time: bin/rails test test/controllers test/integration/login_test.rb By default test failures and errors are reported inline during a run. Rails options: -w, --warnings Run with Ruby warnings enabled -e, --environment Run tests in the ENV environment -b, --backtrace Show the complete backtrace -d, --defer-output Output test failures and errors after the test run -f, --fail-fast Abort test run on first failure or error -c, --[no-]color Enable color in the output ``` **after** ``` ./bin/rails t --help You can run a single test by appending a line number to a filename: bin/rails test test/models/user_test.rb:27 You can run multiple files and directories at the same time: bin/rails test test/controllers test/integration/login_test.rb By default test failures and errors are reported inline during a run. minitest options: -h, --help Display this help. -s, --seed SEED Sets random seed. Also via env. Eg: SEED=n rake -v, --verbose Verbose. Show progress processing files. -n, --name PATTERN Filter run on /regexp/ or string. --exclude PATTERN Exclude /regexp/ or string from run. Known extensions: rails, pride -w, --warnings Run with Ruby warnings enabled -e, --environment Run tests in the ENV environment -b, --backtrace Show the complete backtrace -d, --defer-output Output test failures and errors after the test run -f, --fail-fast Abort test run on first failure or error -c, --[no-]color Enable color in the output -p, --pride Pride. Show your testing pride! ```
