Cop to enforce the first describe of a spec is defined as RSpec.describe

[schinery]

I've checked the docs and don't believe this can currently be done, but would it be possible to create a cop that enforced the first describe of a spec has been defined as RSpec.describe?

So something like:

# Bad
describe SomeClass do
  describe "#does_something" do
    # ...
  end
end

# Good
RSpec.describe SomeClass do
  describe "#does_something" do
    # ...
  end
end

This is one of the non-goals.

The monkey-patching mode, top-level describe with no receiver, will be removed in RSpec 4. To ease up the process of upgrading, you can use Transpec, which will do the conversion for you.

Cool, thanks @pirj.

I also discovered setting config.expose_dsl_globally = false will make any test not using RSpec. to blow which is good enough for now.
