Test early, test often, test on the device. That is the quality assurance mantra we consider most important when it comes to testing Android applications. Testing your applications need not be an onerous process. Instead, you can adapt traditional QA techniques, such as automation and unit testing, to the Android platform with relative ease. In this chapter, we discuss our tips and tricks for testing Android applications. We also warn you—the project managers, software developers, and testers of mobile applications—of the various and sundry pitfalls you should do your best to avoid. We also provide a practical example, in addition to introducing many tools available for automating Android application testing.
