The [Grape API framework](https://github.com/ruby-grape/grape) regularly writes tests like [spec/grape/api_spec.rb](https://github.com/ruby-grape/grape/blob/master/spec/grape/api_spec.rb). When attempting to write a test in a Rails environment similar to the following: ``` describe Grape::Api, type: :request do let(:app) { Class.new(Grape::API) do get 'test' do { foo: 'bar' } end end } it '200s' do get 'test' end end ``` The following exception is thrown: ``` NoMethodError: undefined method `url_helpers' for #<Array:0x00007fb4e4bc4c88> -- 0: .../lib/action_dispatch/testing/integration.rb:330:in `block in create_session' 1: .../lib/action_dispatch/testing/integration.rb:326:in `initialize' 2: .../lib/action_dispatch/testing/integration.rb:326:in `new' 3: .../lib/action_dispatch/testing/integration.rb:326:in `create_session' 4: .../lib/action_dispatch/testing/integration.rb:316:in `integration_session' 5: .../lib/action_dispatch/testing/integration.rb:348:in `block (2 levels) in <module:Runner>' ``` This change explicitly ensures that `app.routes` is an `ActionDispatch::Routing::RouteSet` instance. |
