Plugins - Laziness
Add to favoritesLaziness autogenerates tests for you when your app throws an unhandled exception. In dev mode, it displays the test on the error page; in production, it adds the test to your exception_notification-generated email. What're you waiting for - lazy up!

Testing

Good plugin, it's not a perfect test generator (sometimes the error depends on some kind of data) but it helps the programmer to keep a good test coverage and error tracking system. Anyway, I'll be using this in my projects! Congratulations! :D Best regards, Felipe Giotto.
