Scenario: Sign Up with LinkedIn When I go to the home page And I follow "Sign Up" And I grant LinkedIn access Then I should be on the new user page
My application has a hyperlink that opens the OAuth login on the OAuth provider's website in a new window. Let's presume the simple matter of wiring this up is already coded in my view.
Testing this with Cucumber requires telling the Selenium web driver to interact with the new popup window. We can do this using page.driver.browser.window_handles to find the newest window handle and scoping out actions to that window.
When /^I grant LinkedIn access$/ do begin main, popup = page.driver.browser.window_handles within_window(popup) do fill_in("Email", :with => "email@example.com") fill_in("Password", :with => "password") click_on("Ok, I'll Allow It") end rescue end end
And that's it!
Keep in mind that if you use this test as-is, you will be hitting LinkedIn on the real Internet. This is great if you want a test that will always verify the real API, but not so good for CI, since it is Internet connection-dependent and slow. Consider using something like VCR or Artifice to stub out your service calls.
There's an untapped cash cow out there when it comes to recruiting and her name is LinkedIn. Until recently, only LinkedIn had access to your profile and social graph, but all that changed with the release of their OAuth-based API. I'f you've hooked into Twitter or Google then this authentication process should feel very familiar to you. To help you along, pengwynn released a LinkedIn gem last week.
