Testem supports parallel execution!

It actually has for a while but it had some limitations. It's recently been updated and can speed up your tests greatly! LinkedIn used this feature to take their test suite from 40 minutes to 2 minutes! 🚀😆❤️

You can define multiple test pages to split up the tests by filters:

   "test_page": [

You can even set the number of parallel workers manually or set it to -1 to have testem max out whatever your CI server can handle:

  "parallel": "-1"

If you want to do this in Ember you're in luck! ember-exam makes this super easy! Thanks Trent Willis!

$ ember exam --split=<num> --parallel
