Mocking an incoming request in to rails

Question

I am using FactoryGirl to mock my models for both unit (RSpec) tests and integration (Cucumber) tests. When creating a News factory I create a random image URL, which obviously doesn't exist within the project. When running a Selenium test this get's picked up as a 404.

FactoryGirl.define do
  factory :news do
    title { Faker::Lorem.sentence }
    image { Faker::Internet.relative_url ".jpg" }
    body { Faker::Lorem.paragraphs.join "\r\n\r\n" }

    before :create do
      Timecop.freeze Faker::Date.time
    end

    after :create do
      Timecop.return
    end

    after :build do |article|
      # Somehow mock a 200 response for #{article.image}
    end

    factory :published_news do
      published true
    end
  end
end

What's the best way to mock a response for my image?

Answer 1

You want to do the mock in the test that fetches that image, not in the factory.

Either that or just provide a static image file in the image link (you don't need to test that your model can accept different URL strings).

Answer 2

If you want to return 200, can you not just return it like this?

after :build do |article|
 ["200", "OK"]
end

Answer 3

Just only added in your specs the following:

describe Zomg do
  it 'should get ok' do 
    stub_request(:any, "http://factory-generated-url-here/").to_return(body: '', status: 200)

   # you stuff with request        
  end   
end
