Question

I’m trying to figure out how to run integration tests that are storybased and where AJAX redirects appear during the ‘story’.

Simple login example: I login to the website using

def user.logs_in(email, pwd)
    get root_path

    assert_response :success
    assert_template 'index'

    post :post, session_path, :email => email, :pwd => pwd

    assert_response :redirect
    assert_redirect_to backend_path

    follow_redirect!

    assert_response :success
    assert_template 'index'
    assert session[:user_id]
  end

Unfortunately the login process is AJAX based and insted of a 301-redirect it returns

document.location.href = "<%= backend_path >";

which gives back a 200-code meaning that

assert_response :redirect

fails.

How can i handle AJAX redirects in my integration tests?

If there is no redirect, of course you won’t be able to (successfully) test for it. So instead test for what you are doing: You want the response to be a 200 and the body to be a Javascript snippet. Or just use assert_template, too.

If you want to test if your Javascript-Login-Button actually evals the js body and how the browser reacts to that you would have to use something like Selenium.
