Please run tests by specifying an appraisal, like:
|
|
|
|
bundle exec appraisal <appraisal_name> #{current_command}
|
|
|
|
Possible appraisals are:
|
|
|
|
#{available_appraisals.map { |appraisal| " - #{appraisal.name}" }.join("\n")}
|
|
|
|
Or to simply go with the latest appraisal, use:

|
|

bin/rspec #{shell_arguments}
