Running spinach tests in parallel

Question

I am moving from Cucumber to Spinach for BDD on my rails 4 project. According to parallel-tests documentation on https://github.com/grosser/parallel_tests it should support spinach

rake parallel:features-spinach       # Spinach

but I got that error:

Just want to know if anybody managed to run Spinach in parallel.

Answer 1

Finally I was able to run spinach in parallel. The thing was that paralell testing works only when spinach features are in a default directory

/features 

regardless of spinach.yml setting.

I had them in

/spinach_features

Unfortunatelly parallel tests take longer than regular tests and the output is displayed without colours so basically there are no benefits of using them (at least in my case).
