The Secret to blazing fast, rock-solid acceptance testing on iOS.

Acceptance Testing is one of the essential components of a healthy software development process; unfortunately on iOS this can result in the creation of slow, brittle and highly complex UI automation tests. These can leave you wondering, is it worth it? By revisiting fundamentals this talk explores the role it should play in driving collaboration between business and software and how it can be best applied to iOS.

In this talk you discover an alternative approach to UI based testing. Through using Fitnesse (a lightweight, open-source testing framework) we walk through an example of how to implement Acceptance Tests on iOS that are blazing fast, rock-solid and actually improve the architecture of your app. Increase you and your teams productivity and discover the secret to answering the question "Can we submit yet?" in seconds instead not days.
