Passing cucumber feature: Feature Grader and scenario: Simple Mutation Test, but getting invalid cucumber results.
Commented some code to work on debugger issue
Added ? to Regex::StepResult for single step and stderr to output in feature.rb. Got yml and test to work without mutation, replace expected regex in steps with /Test passed/ to get the feature to pass. Left it failing for now to show error output which is helpful to move forward.
