同步覆盖：在单元测试中极力推荐测量代码覆盖，但是在测试并行程序时使用它，代码覆盖容易产生误导。
Synchronization coverage: Measuring code coverage is a highly recommended practice in unit testing, but when it comes to concurrent programs, code coverage is misleading.
此外，通过提供被注入对象的存根实现、改进测试覆盖率和代码质量，可轻松对编写良好的应用程序类执行单元测试。
Furthermore, well-written application classes can easily be unit tested by providing stub implementations of the injected objects, improving test coverage and code quality.
从浏览器的角度看，自动化的web应用程序测试可能是扩大覆盖您的应用程序其他部分的现有单元测试的一种极好方法。
Automated web application testing from the browser perspective can be a great way to augment existing unit tests that cover other parts of your application.
