minitest-rerun-options

Outputs the command line options to rerun failing tests

Description

This plugin adds a reporter that outputs command line options for failing tests. As an example:

$ ruby test/test_examples/test_with_failures.rb
Run options: --seed 39171

# Running:

.FF..

Finished in 0.001130s, 4424.7788 runs/s, 4424.7788 assertions/s.

  1) Failure:
TestExample#test_another_that_will_fail [test/test_examples/test_with_failures.rb:14]:
Failed assertion, no message given.


  2) Failure:
TestExample#test_that_will_fail [test/test_examples/test_with_failures.rb:10]:
Failed assertion, no message given.

5 runs, 5 assertions, 2 failures, 0 errors, 0 skips

Rerun failed tests options:
--name TestExample#test_another_that_will_fail
--name TestExample#test_that_will_fail
--names TestExample#test_another_that_will_fail,TestExample#test_that_will_fail

Then you can rerun a single failure: ruby test/test_examples/test_with_failures.rb --name TestExample#test_that_will_fail

Or all failing tests: ruby test/test_examples/test_with_failures.rb --names TestExample#test_another_that_will_fail,TestExample#test_that_will_fail

If you are using Rake, it will output the environment variable that Rake uses:

Rerun failed tests options:
TEST_OPTS="--name TestExample#test_that_will_fail"
TEST_OPTS="--name TestExample#test_another_that_will_fail"
TEST_OPTS="--names TestExample#test_that_will_fail,TestExample#test_another_that_will_fail"

Installation

Add this line to your application's Gemfile:

gem 'minitest-rerun-options'

And then execute:

And that's it! This is a Minitest plugin which means that it will be autoloaded.
