Test2VA: Reusing GUI Test Cases for Voice Assistant Features Development in Mobile Applications

智能手机中的语音助手（VA）现在已经成为数百万用户非常流行的功能。一个关键的趋势是自定义VA嵌入的兴起，使用户能够通过语音控制执行他们喜爱的应用程序的定制任务。然而，随着这种巨大需求，很少有人为VA开发支持应用程序开发人员。此外，许多面向用户的VA控制方法甚至会增加开发人员的编程负担。为了减少工作量并提高代码效率，本文提出了一种新的方法，Test2VA，它重用应用程序的测试代码来支持其VA开发。具体而言，Test2VA从GUI测试代码中提取任务完成模式，然后生成执行方法以在一般情况下执行相同的任务。为了识别模式，Test2VA使用基于变异的探索来检测测试用例中可变的GUI事件，然后将其参数化为VA方法。我们对八个真实应用程序的48个测试用例进行了评估。结果显示，Test2VA正确检测到了48个原始测试用例中75.68％的可变事件，然后生成了33个方法并成功执行并手动检查。

Test2VA: Reusing GUI Test Code for Custom Voice Assistant Development

Test2VA proposes to reuse GUI test code to support custom voice assistant development, by extracting task completion patterns and generating execution methods. A mutation-based exploration is used to detect mutable GUI events and parameterize them in the VA method.

The approach is evaluated on 48 test cases from 8 real-world applications, achieving a correct detection rate of 75.68% for mutable events and generating 33 methods that are successfully executed and manually examined. Test2VA reduces the workload and improves code efficiency for app developers in VA development.
