Sanity Testing in QA

Sanity testing is frequently seen as a subset of Regression testing. That speaks volumes about how well its principles and purpose are understood. In order to confirm that specific defects have been fixed in advance, QA engineers do sanity testing after receiving a software build with minimal code modifications.

Sanity testing is a kind of test that determines whether or not testing for the build may continue. During the sanity testing phase, the team’s main goal is to verify the application’s functionality rather than do in-depth testing. Sanity testing is typically done on builds when an urgent production release, such as a significant bug repair, is needed.

One of the most ambiguous terms in software testing is sanity testing. As a result, it regularly comes up in QA Engineer job interview questions. However, that is not the only factor making it a fascinating subject for Quality Assurance testing. QA experts may organise their testing tactics wisely and save valuable hours of testing time by knowing when to use sanity testing. Sanity testing should be thoroughly explained on a good and reliable online quality assurance training platform.

What exactly is the intention of performing this type of testing? It allows: 

  • To examine and confirm the accuracy of recently implemented functionality.
  • To assess how accurate these traits are.
  • To verify that newly implemented changes do not impact the product’s current functions.

The objective is to confirm that the proposed functionality complies with the technical specifications. Sanity testing is a narrow field. But it emphasises the specifics of this space and its surrounding functionality. Let’s imagine a software program you use has a three-step registration process, and step two of the process contains a glitch. After being resolved, the app would need to go through sanity testing on at least two or three of the most popular application platforms for the registration process and flows that depend on it.

Implementation of Sanity Testing 

Sanity testing quickly ascertains how modified modules may affect the system’s overall behaviour. In essence, surface-level testing aids in determining whether the software build is sufficient to move on to the next stage of testing or not. Sanity testing is particularly helpful when there are short deadlines and insufficient time to completely test the build. 

So how exactly does sanity testing work? Only three steps are necessary:

  • List the code’s revisions and newly added features.
  • Check to see if the implemented components meet the specified requirements by evaluating and analysing them.
  • To ensure proper operation, test the required parameters and related functionalities. 

If a sanity test fails, the build is rejected to save the time and costs that would be spent on more rigorous testing. The QA team reports the defect to the development team. If a sanity test passes, QA engineers carry out further testing to check if newly added changes affect previously present components of the system.

Sanity Testing Particularities 

This kind of software testing adopts a deep and focused strategy and includes thorough testing of a few constrained features. But what characteristics does sanity testing have? Here is a brief list of its unique characteristics that you should be aware of.

1. It has been over relevantly stable builds.

This might be a few fixes for a new feature build going live or a bug fix for a build that is already in production. A social media app with a glitch when uploading photographs is nonetheless regarded as stable because it is in use and has a large user base.

2.It is a Quick Check.

Sanity testing immediately reveals the state of the software. You can then plan your next move in light of this. Sanity testing is a quick testing technique that doesn’t cover all the specifics but makes sure that the changes are operating in accordance with the client’s requirements.

3.It is usually Automated.

This statement stands on its own. Automation of sanity checks can speed up results and save time if it is necessary for the project.

In the event that the software receives a request for a modification, new functionality, or bug fix, QA specialists conduct sanity testing. If a software tester doesn’t have time for a complete review, it may be a quick fix. Still, QA specialists prefer to use it as a slender approach to testing where limited functionalities are covered deeply rather than an alternative for regression testing.
