静态和动态测试的区别

静态测试：
静态测试是一种软件测试方法，用于检查软件中的缺陷，而无需实际执行软件应用程序的代码。

在开发的早期阶段进行静态测试以避免错误，因为它更容易找到故障源并且可以轻松修复。使用动态测试找不到的错误，可以通过静态测试轻松找到。

动态测试：
动态测试是一种软件测试，用于分析代码的动态行为。它包括对分析的输入值和输出值的软件测试。

静态测试和动态测试的区别：

Static Testing	Dynamic Testing
It is performed in the early stage of the software development.	It is performed at the later stage of the software development.
In static testing whole code is not executed.	In dynamic testing whole code is executed.
Static testing prevents the defects.	Dynamic testing finds and fixes the defects.
Static testing is performed before code deployment.	Dynamic testing is performed after code deployment.
Static testing is less costly.	Dynamic testing is highly costly.
Static Testing involves checklist for testing process.	Dynamic Testing involves test cases for testing process.
It includes walkthroughs, code review, inspection etc.	It involves functional and nonfunctional testing.
It generally takes shorter time.	It usually takes longer time as it involves running several test cases.
It can discover variety of bugs.	It expose the bugs that are explorable through execution hence discover only limited type of bugs.
Static Testing may complete 100% statement coverage in comparably less time.	While dynamic testing only achieves less than 50% statement coverage.
