What is Sanity Testing? Definition, Process, and Features

In the world of software testing, the idea of sanity testing might be a little perplexing. To be clear, it is a type of regression testing. Like its core testing category, Sanity testing examines if a modification has changed the application’s functioning. But in a shorter amount of time and with fewer test cases, focusing just on the most crucial aspects.

In basic terms, the definition of sanity testing is:

It assesses if the app is built to fulfill the users’ needs. The goal is to see if the software is still working correctly after making minor changes to a piece of the code.

What is Sanity Testing in Software Testing?

Software testing provides a great opportunity for sanity checks, but it’s important to remember that developers may also do sanity checks.

To be more specific, there is no need to wait for an independent tester to do a software sanity test.

Sanity tests, whether informal or formal, are considered an early form of software testing.

What is the Process of Sanity Testing?

It is only carried out once the software product has passed the smoke test and has been approved for further testing by the Quality Assurance team. It assists in determining whether newly added functionality is meeting the set requirements. The test fails if a newly introduced functionality is not able to fulfill the requirements.

If a newly added capability to your application meets a need, the sanity test is passed. When the sanity test succeeds, thorough system testing is performed to ensure that newly included functionalities to your software application do not interfere with the previously installed system and application components.

High-Level Sanity Planning 

Sanity tests are divided into detailed test planning and high-level test planning. The diagram below offers a clear picture of how high-level sanity planning is achieved.  


ImpactQA - Sanity Testing Process

Main Features of Sanity Testing

  • Sanity testing is unscripted
  • It works once regression testing is completed
  • This testing process is undocumented
  • Enabled quick testing and speedy assessment
  • Narrow testing approach where limited functionalities are thoroughly examined
  • Sanity testing is not automated and should be performed manually
  • It only operates on functions that have been changed or aren’t working properly

Core Advantages of Sanity Testing

  • Quick identification of flaws at an early stage
  • App stability can be validated at a faster pace due to quick bug reporting
  • Simpler execution and no need for documentation
  • Sanity testing immediately determines the existing condition of your software
  • If flaws are found during Sanity testing, the build is rejected, thereby saving a lot of time and resources

What is the Importance of Sanity Test Cases?

Sanity tests, as previously stated, are not automated. However, there may be some debate over a hidden cost associated with using this strategy, which includes more time and effort spent developing effective test cases and assessing test findings.

Let’s have a look at the method of ad-hoc sanity testing. Every test occurs in the present, and it tends to fade away fast afterward. As a result, you should memorize as many sanity tests as possible in case you need to test the same software application again. When you put in time and effort, and the payoff is dependent on a consistent attempt at meticulously repeating the test cases, this becomes tough to achieve.

Difference Between Sanity Testing & Smoke Testing

  • Sanity testing is done when the build is relatively stable, whereas smoke testing is done at the initial level.
  • We call sanity testing a subdivision of regression testing. On the other hand, smoke testing is known as a subdivision of acceptance testing.
  • Sanity testing is performed after the completion of regression testing. Smoke testing is executed on every build.
  • Sanity testing is considered always stable. Smoke testing can either be stable or unstable.


Sanity testing is used to determine whether or not more testing is necessary for a software application. It is critical because it saves time when a problem in the system is discovered. Sanity tests also give you a quick update on the progress of the release, so you can plan your next actions accordingly.
