问题：
What are unit tests, integration tests, smoke tests, and regression tests? 什么是单元测试，集成测试，冒烟测试和回归测试？ What are the differences between them and which tools can I use for each of them? 它们之间有什么区别，我可以为每个工具使用哪些工具？
For example, I use JUnit and NUnit for unit testing and integration testing. 例如，我将JUnit和NUnit用于单元测试和集成测试。 Are there any smoke testing or regression testing tools? 有烟雾测试或回归测试工具吗？
