Question

I am trying to use rails generate to generate an integration test by running

rails generate integration_test static_pages

However, instead of invoking rspec and creating static_pages_spec.rb in the spec/requests directory it shows me this error:

What can I do to remedy this?

Answer 1

I just had this exact same issue. I had typed root into my routes.rb file and forgot to add an argument. I see the same thing happens if I put get or post without any arguments.

Make sure to check your routes!
