烟雾测试和回归测试之间的区别

先决条件–软件测试
1.烟雾测试：
冒烟测试是指对新开发的软件版本执行的初始测试。通过这种软件测试，可以清楚地看出，软件产品的核心功能可以完美地运行而没有任何问题。如果软件无法通过冒烟测试，则将其视为损坏的版本，并转发给开发人员。

在对软件进行任何功能测试之前，必须先进行一些测试。此冒烟测试是在软件开发生命周期(SDLC)的初始开发阶段进行的。冒烟测试也称为“表面级别测试”，因为它在实际过程测试之前进行，并且不执行深度测试，只是验证核心功能是否正常工作。冒烟测试不仅被称为表面层测试，还被称为“构建验证测试”，因为它可以验证软件的初始构建。

例子 –
想想公交车票预订站点，在此烟雾测试示例中，测试人员将确保站点登录函数，更改密码，预订座位，取消座位，预订通知功能等正常运行。

2.回归测试：
回归测试是指对软件进行深入的检查，以确保最近的代码更改不会对现有功能造成不利影响。意味着它是在漏洞修复或需求变更之后对软件变更进行的验证。完成针对更改的需求的健全性测试后，将执行回归测试以了解所有受影响的功能。

因此，回归测试主要在任何错误修复，代码修改，需求变更，缺陷修复或任何新模块开发之后进行。进行此操作是为了进行软件更改后的影响分析。

例子 –
如果我们以上述相同的示例为例，则回归测试示例不仅包括使公交车票预订站点正常工作的基本功能，还使我们能够测试座位预订的更复杂的用例，例如旅行地点，预订促销代码，国际税等等。

烟雾测试和回归测试之间的区别：

S.No.	Smoke Testing	Regression Testing
01.	Smoke Testing is the Surface Level Testing to verify stability of system.	Regression Testing is the Deep Level Testing to verify the rationality of system.
02.	Smoke Test is always followed by Regression Test.	Regression Test is always carried out throughout the testing phase.
03.	Test Cases of Smoke Test is a part of Regression Testing and covers only the core functionalities.	Regression testing is obtained from functional specification or Software Requirement Specification (SRS).
04.	Smoke tests are performed by the developers.	Regression tests are performed by the professional testers.
05.	Smoke tests are performed quickly to confirm whether to accept or reject the build.	Regression tests are not accountable for accepting or rejecting a software build for further testing procedures.
07.	Cost of Smoke testing is low.	Cost of Regression testing is little bit high.
08.	This testing isd ocumented or scripted.	This testing is not documented or scripted.
09.	It is also know as Build Verification Testing.	It is not known by any other name.
10.	Requirement of time and manpower is less than Regression Testing.	Requirement of time and manpower is less more than Smoke Testing.
