Constructor Details

#initialize(passed_in_args = []) ⇒ CukeRunner

When an instance of CukeRunner is initialized it will take the arguments passed in and combine them with its own default args. Those args are a mix of ones specific to ParallelTests, and ones for Cucumber.

In essence we are getting ParallelTests to pass the following to Cucumber along with whatever args are passed in when Quke is called.

[my_features_folder, '-r', 'lib/features', '-r', my_features_folder]

Its these args that pass our features directory to cucumber along with the user’s. So to break it down

- +my_features_folder+, first arg tells Cucumber where the feature files
    are located
- +-r 'lib/features'+, tells Cucumber to require our features folder.
    This is how we get it to use our +env.rb+ which handles all the
    setup on behalf of the user (the point of Quke) to do things like
    use Browserstack, or switch between running against Chrome or
    firefox locally
- +-r my_features_folder+, if you specify a different folder for
    or wish to test just specific features, you are required by Cucumber
    to also require the folder which contains your steps. So we always
    set this to be sure to handle tagged scenarios, or features run in
    parallel.
