Behat is exploding with Fatal require errors

If you're getting fatal errors due to missing, required files, there's a good chance that you're running into the issue described here:

In short, a menu rebuild is being called from outside of the Drupal root, thereby exploding your registry. For me, this was caused by views_content_cache, which calls views_invalidate_cache() and triggers a menu rebuild after certain entity operations. Here's how I got around that.

Unfortunately, many people don't use this option. Maybe they don't know about it, maybe they've forgotten about it, or maybe they don't like. Well, the Views Cache Bully module is here to say "Too bad. You're gonna cache your views, and you're gonna like it."
