minitest-rerun-failed

master branch CI

Easy rerun of failed tests with minitest.

Example screenshot

Goals

  • Outputs all failed tests in short summary at end of test run.
    • To console and / or to file
    • Optionally includes line numbers
  • Lists seed of run for rerun.
  • [TODO] Executable for running only failed tests
    • Until then, use something like
      • ruby $(cat .minitest_failed_tests.txt)
      • bundle exec rails test $(cat .minitest_failed_tests.txt)

Installation

Add this line to your application's Gemfile:

gem 'minitest_rerun_failed'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install minitest_rerun_failed

Usage

Use it like any Minitest::Reporters like such:

Minitest::Reporters.use! [
  Minitest::Reporters::ProgressReporter.new, # This is just my preferred reporter. Use the one(s) you like.
  Minitest::Reporters::FailedTestsReporter.new(verbose: true, include_line_numbers: true)
]

Options

  • include_line_numbers: Include line numbers in outputs. Defaults to true
  • verbose: Output to stdout. Defaults to true
  • file_output: Output to file. Defaults to true
  • output_path: Path to place output files in. Defaults to '.'

Other

Why line numbers instead of test names? What if the lines change as I am fixing things?

Line numbers were much easier to implement. If you find a good way to output test names instead, please open a PR with tests to add it as an option.

As for if line numbers change, the most likely outcome is that the whole file will simply be run instead of a single test. You can also use the option include_line_numbers: false to always output whole files for greater safety.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
