Unit level test has been widely recognized as an important approach to improve the software quality, as it can expose bugs earlier during the development phase. However, manual unit level test development is often tedious and insufficient. Also, it is hard for developers to precisely identify the most error prone code block deserving the best test coverage by themselves. In this paper, we present the automatic Unit level test framework we used for intel media driver development. It can help us identify the most critical code block, provide the test coverage recommendation, and automatically generate >80% ULT code (~400K Lines of test code) as well as ~35% test cases (~7K test cases) for intel media driver. It helps us to greatly shrink the average ULT development effort from ~24 Man hours to ~3 Man hours per 1000 Lines of driver source code.

翻译：单位级测试被公认为是提高软件质量的重要方法,因为它可以在开发阶段早期暴露错误。 但是, 人工单位级测试的开发往往乏味且不足。 此外, 开发者很难精确地识别最容易出错的代码块, 由他们自己来进行最佳测试。 在本文中, 我们展示了用于开发英特尔媒体驱动器的自动单位级测试框架。 它可以帮助我们识别最关键的代码块, 提供测试覆盖建议, 并自动生成超过80%的逻辑代码( ~ 400K 的测试线) 和 ~ 35%的测试案例( ~ 7K 测试案例), 用于英特尔媒体驱动器的测试案例。 它帮助我们大大缩短平均的科技开发努力, 从~ 24 man 小时到~ 3 man 小时 每 1000 的驱动器源码 。
