TurboTests

turbo_tests is a drop-in replacement for grosser/parallel_tests with incremental summarized output. Source code of this gem is based on Discourse and RubyGems work in this area.

Incremental summarized output doesn't fit vision of parallel_tests author and RSpec doesn't support built-in parallel testing yet. This gem will not be useful once one of the issues above will be implemented.

Why incremental output?

parallel_tests is great, but it messes output:

$ bundle exec rake parallel_tests:spec[^spec/search]
.................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

turbo_tests output looks like regular rspec:

$ bundle exec turbo_tests

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec 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 tags, and push the .gem file to rubygems.org.
