      Could not find an RSpec example group that looks like a request. The
      describe/context description must start with an uppercase HTTP verb
      like "GET" or "POST".

      Try something like:

        describe "GET /foo" do
          it { is_expected.to have_http_status(:ok) }
        end
    END_ERROR

  example.send(
    method.downcase,
    interpolate(path, example),
    params: example.params,
    headers: example.headers,
  )
end

#interpolate(path, example) ⇒ Object
