Easy way to detect whether rspec or cucumber is running?

问题

I'm currently checking in some places whether code is being executed in test mode, by

Rails.env.test?

I would like to go one step further, and check whether it is Cucumber or Rspec executing the code, in order to finetune some methods for i18n (which I do want to run differently in a Cucumber context, but not in an Rspec context)

Is there any way to do this?

回答1:

You can set RAILS_ENV=cucumber and then ask:

Rails.env.cucumber?

回答2:

I'm using the cucumber-rails gem, and with that at least you can do defined?(Cucumber). That will return "constant" if you're running a cuke or nil if you're running a spec.
