How to set the referrer in an _integration_ test

Question

Rspec can't access the HTTP referrer.

My user_sessions#create action contains: redirect_to :back, which Rails can only execute by reading the HTTP referrer.

Stackoverflow contains plenty of posts about how to set/mock/whatever the referrer in a controller spec. The general vibe is request.env["HTTP_REFERER"] = etc etc.

But I need redirect_to :back to work in an integration test that looks like this:

click_link "login"
page.current_path.should == "/login"
fill_in "user_session_email", :with => @user.email
fill_in "user_session_password", :with => @user.password
click_on "submit_user_session"
page.current_path.should == new_order_path
click_on "submit_order"

How can I do this?

Bonus points if the solution tells this spec to store the referral for every URL it visits (so the test is robust) and has no impact on other specs (for speed).

Answer 1

Capybara.current_session.driver.header 'Referer', 'http://example.com'

It looks like you're using Capybara, you can use Capybara to explicitly set the referer. You would have to update it whenever you wanted it to change, and if you needed to remove it you could set it to nil.

Maybe a bit cleaner:

referer = 'http://example.com'
Capybara.current_session.driver.header 'Referer', referer

Answer 2

Here is the code used to implement the redirect_to method:

if referer = request.headers["Referer"]
  redirect_to(referer, :status=>status)
else
  raise RedirectBackError
end

Have you tried to set request.headers['Referer'] directly ?
