Test driven development process, mobile applications, automatic GUI testing
The rapid expansion of mobile device market requires software vendors to deliver mobile applications with high quality within a short time limit. In this paper, we present an iterative test driven development(TDD) process for mobile applications running on Android. In each iteration of this process, developers can specify a new feature or improvement by specifying GUI elements and corresponding GUI behavior in a test case, then write or refactor code to pass the test. This process utilizes mGUITester, a test engine specially designed for Android's applications, to execute the test cases automatically. Empirical studies on two typical applications show that the TDD process can help semi-skilled developers improve product quality within limited time, but does not work equally well for beginners and professionals
