Sanity Testing Vs. Smoke Testing: All You Need to Know!

Sanity Testing Vs. Smoke Testing Difference Between Them

What is Smoke Testing?

Smoke testing is a type of software testing service designed to ensure that the program's acute functionalities function properly. This is a subset of acceptance testing, used to test all the functions of the system/product.

Rather than eliminating errors in the software's core, smoke testing aims to eliminate errors in the software's code. This prevents futile efforts in the later phases of the SDLC by detecting errors at the preliminary stage. Smoke testing provides insights at an early stage, allowing integration issues and other errors to be detected earlier.

You can perform a smoke test manually or using automated tools. Automated smoke tests are frequently initiated by the process that generates the build. By automating the tests, you can run them faster and get feedback faster, allowing you to respond more quickly.

What is Sanity Testing?

Sanity testing is done to determine whether newly added modules to an existing software build are functioning as expected and are ready to move on to the next stage of testing. It is a subset of regression testing and offers quality assurance services by assessing the efficacy of software regressions.

To ensure that bugs have been fixed after the build, sanity testing is performed. In addition to being referred to as a subset of regression testing, it is a software testing service that serves as a checkpoint to determine whether or not screening for the project can continue.

Sanity testing is primarily used to ensure that the proposed functionality or changes function as intended. The sanity test also determines whether seamless end-to-end testing of the build can be carried out if minor changes to the code need to be made. The testing team, however, dismisses the software build if the test is unsuccessful, resulting in time and money savings.

There is a misunderstanding that smoke testing and sanity testing are the same, but each of these types of testing has its own goals and considerations.

After the Quality Assurance team has approved and cleared the smoke test, sanity testing is carried out. Instead of performing in-depth testing, the main goal of this testing is to validate the application's functionality. The test cases for execution are chosen when sanity testing is done for a module, functionality, or entire system and they touch only the important bits and pieces. Apparently, it is a wide but shallow test.

Sanity Testing vs. Smoke Testing

In addition to determining whether the code is eligible for additional tests, smoke testing and sanity testing are indeed quick to check the code's fundamental functionality. Smoke testing, on the other hand, verifies that a program's critical functionalities operate without error, while sanity testing verifies that the proposed functionality performs as expected.

The majority of the time, we swap smoke testing and sanity testing. Let's examine the difference between these two testing procedures in more detail to dispel this misunderstanding.

Let's Now Look at How They are Different From One Another:

Smoke testing aims to validate stability, whereas Sanity testing aims to validate reason.

Smoke testing is performed by software developers and testers, whereas sanity testing is performed exclusively by testers.

During smoke testing, a system's important functions are verified, while during sanity testing, new functions are verified including bug fixes.

Sanity testing is part of regression testing, while smoke testing is part of acceptance testing.

In contrast to smoke testing, sanity testing does not have any documented or scripted procedures.

A smoke test verifies the entire system from beginning to end. As opposed to sanity testing, which verifies a specific component of the system, sanity testing examines the entire system.

While sanity testing verifies that recently introduced functionalities, bugs, etc., have been fixed, smoke testing verifies that the program's critical functionalities are operating without error.

During smoke testing, the software build could be either stable or unstable. At the time of sanity testing, the software build is largely stable.

Initial builds are subjected to smoke testing, while relatively stable builds are subjected to sanity testing.

Smoke testing is a component of basic testing, whereas sanity testing is a component of regression testing.

Typically, smoke testing is carried out after each new build release. However, sanity testing is set up when there isn't enough time for extensive testing.
