Sanity Testing Vs Smoke Testing - Software Engineering

Smoke Testing is a type of testing that is done to ensure that the acute functionalities of the program are working fine. It is also known as a subset of acceptance testing, and it is used to test all over the function of the system/product. On the other hand. 

Sanity Testing is done to check the bugs have been fixed after the build. And it is also known as a subset of regression testing. There is confusion between smoke testing and sanity testing that these two types of testing are the same, but both smoke testing and sanity testing have their objectives and priorities. So, 

Sanity testing and smoke testing are two important testing techniques in software engineering that are often used to check the basic functionality of a software application. Although both techniques are used to check the basic functionality of a software application, there are some key differences between them.

Smoke Testing: Smoke testing is a testing technique that is used to check the basic functionality of a software application or system after a build or release. This testing is done to ensure that the build is stable enough for further testing. Smoke testing involves a quick and shallow check of the software application to verify that it is functioning properly and that there are no critical defects that could prevent further testing. Smoke testing is typically performed by testers or developers before any detailed testing is performed.

Sanity Testing: Sanity testing is a testing technique that is used to check that specific functionality or components of a software application are working as expected after making changes or fixing defects. The main objective of sanity testing is to verify that the changes made to the application have not introduced new defects or issues in the specific functionality or components. Sanity testing is typically performed after regression testing and is focused on specific areas of the application.

Key differences between smoke testing and sanity testing are:

Objective:
Smoke testing aims to ensure that the build is stable enough for further testing, while sanity testing aims to verify that specific functionality or components of the application are working as expected.

Scope:
Smoke testing covers the entire system or application, whereas sanity testing is focused on specific functionality or components.

Timing:
Smoke testing is typically performed after a new build or release, while sanity testing is performed after making changes or fixing defects.

Depth:
Smoke testing is a shallow check of the software application to verify that there are no critical defects, while sanity testing is a more detailed check of specific functionality or components of the application.

In summary, smoke testing and sanity testing are both important testing techniques that are used to ensure the quality and reliability of software applications. Smoke testing is used to ensure that the build is stable enough for further testing, while sanity testing is used to verify that specific functionality or components are working as expected after making changes or fixing defects. Smoke testing is a shallow check of the entire application, while sanity testing is a more detailed check of specific functionality or components of the application.

Here in this post, we will show the difference between Smoke Testing and Sanity Testing. Below is a detailed comparison:
