RSpec/Rails/InferredSpecType doesn't check to see if you're actually using Rails

[Mr Rogers]

We're working on a Sinatra app.

When we have RSpec/Rails/InferredSpecType enabled (by default) and we run auto correct, it removes all the type: :whatever_type params from specs. But because we're not in Rails, those inferred types don't actually apply.

If I try adding

describe MyDomain::App, type: :feature do
  ... tests here
end

Autocorrect makes it

describe MyDomain::App do
  ... tests here
end

And if I try adding infer_spec_type_from_file_location! which works on a Rails app, I get

An error occurred while loading ./spec/whatever_spec.rb.
Failure/Error: config.infer_spec_type_from_file_location!

NoMethodError:
  undefined method `infer_spec_type_from_file_location!'

Feels like rubocop-rspec should check to see if Rails is involved before enforcing and auto correcting that rule.

We can disable the rule for now but it feels like a workaround.

We plan on extracting rubocop-rspec_rails. It won’t be included by default with rubocop-rspec.
I suggest you to configure your project to only run relevant cops. And you can skip whole departments:

RSpec/Rails:
  Enable: false

[Mr Rogers]

Thanks for the tip. Didn't realize you can skip a bucket like that.
