Writing/Porting Tests Detects Bugs!

When I read about a test that runs well in SeaMonkey being moved from testing/mochitest/ to browser/ yesterday (as it tests stuff that is actually internal to browser/ JS), I decided it would be good if SeaMonkey would still run it. And as I was already looking into moving/porting a browser test, I decided I would look into what other tests from browser/base/content we should have.

Following that, I spent the whole day trying tests and porting those that are useful to suite/browser - finding a number of things to add to the Firefox to SeaMonkey porting list as a number of tests were for features we haven't implemented yet (helpwanted!) as well as a few bugs in SeaMonkey, which I either fixed right in the patches for adding the plain mochitests and browser-chrome tests or marked todo() relying on followup bugs to fix them.

In the end this should result in easier extensible browser context menus and better accesskeys within them, improved feed detection, and plugins handling improvements - in addition to detecting more regressions in the tested areas when we're doing future work.

What I really like with that work though is that it uncovers existing bugs (that are sometime easy to fix) in addition to early detecting future ones.

That's why I proposed increasing automated test coverage as a Summer of Code project for SeaMonkey - if you are a student and want to learn Mozilla code, please consider applying for this one, you'd even get paid for it!
