How to create a Mock in Ruby On Rails (Carrierwave) to simulate sending an image to a S3 (Cloudinary)

I created a project creation system with image. My images are uploaded to Cloudinary + Carrierwave.

Before the Test did not break because I sent to the server, but when I integrated in Cloudinary the code broke.

I think I know what it can be, but I don’t know how to fix it. When it inserts it into the Cloudinary database it returns a random value, as I do to 

   **within(".asset_project") do
      expect(page).to have_css("img[src*='project.png']")
   end**

the TDD is correct, because I think this is it.

ruby-on-rails rspec mock

  • if it puts a random value, you cannot access the model and compare if the one in the view is the same as the model’s?

  • If I understand the question, you need to "mock" a call to an external API. Is that? If yes, using the Gem Webmock does not solve?

  • solved to Gem! Thank you very much!
