London Ruby User Group:Javascript Testing

Javascript Testing
Chris O'Sullivan loves testing, and it's been eating away at him that he can't test the javascript he writes for his rails apps. In this talk he'll be showing off how he finally worked out how to test this stuff and return to the shores of Testingland.

Review:
In this talk, Chris O'Sullivan introduces the issues he saw with his Rails development, Javascript, and how there is very limited testing. Chris introduces the changes that need to made before beginning Javascript testing (mainly that you don't view javascript as a necessary evil) and how you set up a Rails application for javascript tests.

Chris then gives a live demonstration of how to use NewJS to test a very basic application. The process looks extremely simple and straightforward for unit testing a javascript function. Chris also demos how NewJS can be used with a javascript function that works on data within the web page.

Overall it seems like Chris is introducing a very useful idea that all Ruby developers who use javacript within their projects should take into consideration. It will certainly produce more reliable, unit tested code before reaching the integration testing phase.
