PreviousNext have been using Behat to test Drupal 7 sites for some time now. More recently, there has been a big push to introduce Behat tests in Drupal 8. So what is it all about?
There hasn't been an update for some time now; things have quieted down a bit, I am mostly just writing drivers now (and coach people on migrate). MongoDB module caught up with the latest config changes and so the module works again.
