What is Sanity Testing? Definition, Process, and Features

What is Sanity Testing? Definition, Process, and Features

The concept of sanity testing may be a little confusing in the field of software testing. It is a kind of regression testing, to be clear. Sanity testing investigates whether a modification has altered how the application operates, just like its core testing category. But in a shorter period of time, with fewer test cases, and concentrating just on the most important elements.

It determines if the app was developed to meet the needs of the users. The objective is to check whether the software continues to function properly following minor code modifications.

What is Sanity Testing in Software Testing?

Sanity checks are a terrific opportunity during software testing, but it’s vital to keep in mind that developers can also perform sanity checks.

To be more precise, a software sanity test does not require the services of an independent tester.

Sanity checks are regarded as an early stage of software testing, whether they are informal or formal.

What is the Process of Sanity Testing?

It is only performed once the software product has passed the smoke test and been given the go-ahead by the quality assurance team for additional testing. It helps determine whether newly added functionality complies with the specifications. If a newly added functionality cannot satisfy the requirements, the test fails.

The sanity test is passed if a newly added feature of your programme satisfies a need. In-depth system testing is carried out once the sanity check is successful to make sure that the newly added functionalities to your software application do not conflict with the already installed system and application components.

High-Level Sanity Planning

Sanity testing are broken down into high-level and detailed test planning. The process of high-level sanity planning is illustrated in the diagram below.

High-Level Sanity Planning

Main Features of Sanity Testing

  1. Sanity testing happens naturally.
  2. Once regression testing is over, it functions.
  3. This testing procedure is not recorded.
  4. facilitated rapid testing and evaluation
  5. Narrow testing strategy that focuses on extensively testing a small number of functions
  6. Sanity testing should be done manually because it cannot be automated.
  7. It only works with functionalities that have been altered or aren’t functioning correctly.

Core Advantages of Sanity Testing

  1. Early detection of faults and quick identification of them
  2. Quick bug reporting enables faster app stability validation.
  3. reduced complexity and absence of documentation
  4. Sanity testing instantly ascertains the state of your programme.
  5. Sanity testing uncovers issues, therefore the build is rejected, saving a tonne of time and resources.

What is the Importance of Sanity Test Cases?

Sanity checks are not automatic, as was previously indicated. There may be some disagreement regarding a potential hidden cost of employing this tactic, which entails spending extra time and effort creating efficient test cases and analysing test results.

Let’s look at the ad-hoc sanity testing technique. Every test takes place in the here and now, and it usually finishes quickly. In order to prepare for the possibility of having to test the same software programme again, you should memorise as many sanity tests as you can. This is challenging to accomplish when time and effort are invested and the reward depends on a persistent effort to meticulously replicate the test cases.

Difference Between Sanity Testing & Smoke Testing

  1. Smoke testing is carried out at the initial level, while sanity testing is carried out when the build is comparatively stable.
  2. A subset of regression testing is what we refer to as sanity testing. However, smoke testing is seen as a subset of acceptability testing.
  3. Regression testing is finished before sanity testing is conducted. Every build is subjected to smoke testing.
  4. Sanity testing is seen as constant. Testing with smoke can be either stable or unstable.


Sanity testing is performed to assess whether more testing of a software program is required. It is essential because it buys time when a systemic issue is found. Sanity checks also provide you with a brief update on the status of the release, allowing you to prepare your subsequent actions.
