Background audio in iOS is supposed to be as simple as entering a setting in your Info.plist and making sure your kAudioSessionProperty_AudioCategory is appropriate. This is true unless your audio is part of a movie file or is played in a movie player that has just played video — suddenly it becomes fiddly, hard to test, unreliable and changeable from version to version of iOS.
In my last two posts, I've shown a Mac app with full unit tests and an iPhone app with full unit tests. The reality though is that I do not write or test code this way. In this post, I look at why so few applications are actually developed using unit tests. I'll also look at the alternate approaches — both manual and automated — that are normally used to maintain high quality and low bug rates in application development.
In this post, I present a complete Cocoa Touch iPhone application implemented with unit tests for all created code. I'll look at setting up build and debug targets and executables for both Application and Logic tests, and show you some of the differences between Application and Logic tests. The code for this post is an iPhone version of the Mac post I presented last week.
In this post, I present a complete Cocoa Mac application implemented with unit tests for all created code. I'll create the tests first and then only add the code required to make the tests pass, largely following a test-driven development (TDD) methodology. Next week I'll show the configuration and implementation of this project as an iPhone application for the benefit of Cocoa Touch developers.
Automated testing of application user interfaces can be tricky since user interfaces are designed for use by humans not automated tools. The iPhone is particularly challenging since existing tools that aid user interface testing on the Mac are not available. This post will show you a way to run automated, scripted tests on an iPhone app's user interface.
The iPhone lacks specific methods to create UIEvent and UITouch objects. I'll show you how to add this functionality so you can write programmatically driven user-interfaces.
