Getting all cookies from various BeHat/Mink browser drivers

Thanks! I had no idea that ->getWebDriverSession()->getAllCookies() even existed. This method wasn't part of the DriverInterface but specific to the Selenium2Driver implementation, which is why I completely overlooked it.

Glad you found this useful. This was kind of a hack because I wanted to be able to reuse authenticated sessions across tests, as described here: https://www.gnaritas.com/2017/04/26/automated-testing-for-wordpress-4/

In my case, I needed to download a file using Guzzle while running Selenium tests. Downloading files using Selenium and moving them to the right location on the Docker container that runs Behat tests was a pain. The problem with Guzzle, however, is that it needs the cookie, since the file download needs authentication too. It's really the dual approach to accessing my SUT that made it necessary to extract cookies from Selenium and put them in a Guzzle CookieJar. I'll probably need to blog about this too :)
