冒烟测试和回归测试的区别

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构建执行的初始测试。通过这种软件测试，可以清楚地表明软件产品的核心功能运行良好，没有任何问题。如果在任何情况下软件未能通过冒烟测试，则将其视为损坏的构建并转发回开发人员。

一些测试是在任何功能测试之前完成的，任何详细的功能测试都是在软件上完成的。此冒烟测试在软件开发生命周期 (SDLC) 的初始开发阶段进行。烟雾测试也称为“表面级测试”，因为它发生在实际过程测试之前，并且不执行深度测试，只是验证核心功能是否正常工作。冒烟测试不仅称为表面级测试，还称为“构建验证测试”，因为它可以验证软件的初始构建。

例子 –
想想巴士票预订站点，在这个烟雾测试示例中，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、预订通知功能等工作正常。

2. 回归测试：
回归测试是指对软件进行深入和彻底的检查，以确保最近的代码更改没有对现有功能产生不利影响。意味着它是在错误修复或需求更改后对软件更改的验证。完成变更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、需求更改、缺陷修复或任何新模块开发之后进行。这样做是为了在任何更改后对软件进行影响分析。

例子 –
如果我们以上述相同的示例为例，回归测试示例不仅包括使 Bus Ticket Reservation 站点正常工作的基本功能，还允许我们测试更复杂的座位预订用例，例如旅行位置、预订促销代码、国际税等等。

冒烟测试和回归测试的区别：

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.
