Yosemite, Zeus, and the parallel_tests gem!

Rails
1

Here are the steps to move away from zeus-parallel_tests.

Once you do that, you can run the your parallel_tests without zeus. I showed in this article Fast Tests: Comparing Zeus With Spring on Rails 4.1 and RSpec 3 that it doesn’t make much of a difference using a loader like Zeus when running parallel_tests.

Then you can run your parallel_tests without zeus per the instructions for the parallel_tests gem, like this:

parallel_rspec spec

Steps to remove zeus-parallel_tests

1. Uninstall zeus:

gem uninstall zeus

2. Install latest zeus:

gem install zeus

3. Remove zeus-parallel_tests gem from Gemfile

4. Update parallel_tests gem

bundle update parallel_tests

5. Run zeus init to create new versions of custom_plan.rb and zeus.json

Your diffs should be similar to what’s shown below.

zeus init
