I've recently found that my ability to add new features and squash bugs has outpaced my ability to do full end-to-end tests. To help with this, I created Spark Runner for automated website testing. It will create and execute a plan for tasks you give it in plain text like "add an item to the shopping cart" or you just point it at your front end code and have Spark Runner create the tests for you. It also makes nice reports telling you what's working and what's not.
New project, so feedback is welcome.
