Where should I store methods to make them available both to my application and to RSpec?

Question

I need to create some methods that are available both to my application (models, views and controllers) and to RSpec.

Specifically I need to create some path_helper

Answer 1

the Rspec-rails gem seems to support helper testing

the gem can make helpers available in any of your specs : "Writing specs for your helpers is a snap. Just tell the Example Group the name of the helper and the Example Group will expose an object that includes the helper".

Answer 2

Haven't tried it, but this looks like an interesting approach to the problem: Adding rspec test for library module doesn't seem to pickup Expectations and Matchers

A model we often use when testing Modules is to include the module in either a class created for the test (inside the spec file) or included inside the spec itself.

Answer 3

You can make RSpec include a module by (in spec/spec_helper.rb):

RSpec.configure do |config|
  config.include YourModule
end

If you want to use routing path helpers, you can include them like this:

RSpec.configure do |config|
  config.include Rails.application.routes.url_helpers
end
