[Zeus](https://github.com/burke/zeus) is a tool for speeding up your tests by preloading a Rails app.
[parallel_tests](https://github.com/grosser/parallel_tests) also speeds up your tests by running them, well,
in parallel. Two good gems, so why not to use them together? Let's make our CPUs sweat!
## Show me the numbers!

Ready to go?
## Installation
[RailsCast episode #413 Fast Tests](http://railscasts.com/episodes/413-fast-tests)
Add this line to your application's Gemfile:
gem 'zeus-parallel_tests'
And then execute:
$ bundle
You need also to initialize your project with custom Zeus plan:
$ zeus-parallel_tests init
This will create two files in your project:
* custom_plan.rb
* zeus.json
### RVM
For RVM users it is recommended to install rubygems-bundler gem.
## Usage
First [follow instructions](https://github.com/grosser/parallel_tests) and prepare
your application to use parallel_tests.
Launch another terminal and run zeus' master process:
$ bundle exec zeus start
Then you can run your parallel specs:
$ zeus parallel_rspec spec
or your cucumbers:
$ zeus parallel_cucumber features
## What is supported?
* rspec
* cucumber
* guard-rspec since v2.5.2 (just pass `zeus: true` and `parallel: true` into configuration hash, you can play with `bundler: false` option to speed things up)
* caching: you must set `config.cache_store = :memory_store` as Zeus will not reload the various cache files used by parallel_tests instances
## TODO
* minitest support
