Parallel scenarios?

[xtrasimplicity]

Hi there,

Firstly, thanks for creating such a useful gem - it's helped reduce the duration of our CI pipelines tremendously!

This may be indicative of issues in the size of our RSpec features, but I've noticed that parallel_tests seems to work best with a one-scenario-per-file setup. That is, if there's 10 scenarios in a single RSpec spec file, parallel_tests detects it as one test and "allocates" it to one runner.

Is there currently a way to "extract" all specs from a file, in such a way that multiple runners could process different specs in a single file at once?
i.e. Given the following spec file:

# my_feature_spec.rb
require 'spec_helper'
RSpec.describe 'My Cool feature', type: :feature do
  it 'does the first thing' do
 end
  it 'does another thing' do
 end
end

I would expect the following on a machine with 2 CPUs/cores:

CPU 0:  my_feature_spec:3
CPU 1: my_feature_spec:5

Is this possible? If not, would you be open to a PR adding this?

Thanks!

@grosser, apologies for the ping, but any thoughts on this one? :)

https://github.com/grosser/parallel_split_test does what you want

parallel_tests is trying to stay at the file level to keep the integration simple

this talks about parallel scenarios for cucumber, might do the trick or get close to a solution #679

Thanks, @grosser - much appreciated!

Would you be open to a PR which updates the Readme to mention that parallel_tests is intended to act at the file-level, and to recommend parallel_split_test where test-level concurrency is required?

sounds good! ... best under tips section or so
