How do I mock an OmniAuth hash using Rails and minitest?

Question

I\'m using Rails 5 with minitest. I want to mock logging into my sessions controller, which relies on omniauth (I use Google and FB for login). I have this in my controlle

The OmniAuth docs state

When you try to test the OmniAuth, you need to set two env variables

and provide examples using RSpec

before do
  Rails.application.env_config["devise.mapping"] = Devise.mappings[:user] # If using Devise
  Rails.application.env_config["omniauth.auth"] = OmniAuth.config.mock_auth[:twitter]
end

In your case, it seems like you may need to set

Rails.application.env_config["omniauth.auth"] = OmniAuth.config.mock_auth[:google]

in your setup_omniauth_mock method, after the call to OmniAuth.config.add_mock.
