UnitTesting on the iPhone
15 Nov 2010
I have to admit, that I find xcode and objective-c the most challenging developing environment I have ever tried. Specifically, I have struggled to find an easy way of including unittests for an application. Even though it comes with some unittest templates, I haven’t successfully put it to work. Can’t say I have tried that much either; it all seemed to complicated to be worth it…
This weekend, the following tweet got my attention:
![TDD for iPhone Development : http://www.vimeo.com/16722907][2]
The video shows a step-by-step guide on how to get started with unittesting for the iPhone. It looked great, and not that complicated, so I decided to give it a try. 10 minutes later, only delayed by a mysterious “Failed to launch simulated application: Unknown error.”-error*, I had my first unittest up and running in the simulator.
If you develop for the iPhone, and either have struggled with unittesting, or just never tried, I will recommend you watch the video. The steps followed in the video is thoroughly documented on the authors home page.
*I never found a reason for this error. As for so many other error messages I have encountered in xcode, starting a new project resolved the issue…
