README
TurboTests
`turbo_tests` is a drop-in replacement for [`grosser/parallel_tests`](https://github.com/grosser/parallel_tests) with incremental summarized output. Source code of this gem is based on [Discourse](https://github.com/discourse/discourse/blob/6b9784cf8a18636bce281a7e4d18e65a0cbc6290/lib/turbo_tests.rb) and [RubyGems](https://github.com/rubygems/rubygems/tree/390335ceb351668cd433bd5bb9823dd021f82533/bundler/tool) work in this area.
Incremental summarized output [doesn't fit vision of `parallel_tests` author](https://github.com/grosser/parallel_tests/issues/708) and [RSpec doesn't support built-in parallel testing yet](https://github.com/rspec/rspec-rails/issues/2104#issuecomment-658474900). 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:
```bash
$ bundle exec rake parallel_tests:spec[^spec/search]
.................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
Finished in 1 minute 6.92 seconds (files took 6.95 seconds to load)
2616 examples, 0 failures
.........................................................................................................................................F........................................................................................................................................F..............................................................................................................................................................................................................................................................................................
Finished in 1 minute 35.05 seconds (files took 6.26 seconds to load)
2158 examples, 2 failures

Finished in 1 minute 35.05 seconds (files took 6.26 seconds to load)
2158 examples, 0 failures
```
`turbo_tests` output looks like regular `rspec`:
```bash
$ bundle exec turbo_tests
..........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................F........................................................................................................................................F..............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
Finished in 2 minute 25.15 seconds (files took 0 seconds to load)

```

## 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](https://rubygems.org).
