Sanity testing: what is it? The Foundation

by Syntax Technologies Software Testing Training

In addition to ensuring the quality of the finished result, software testing also aims to cut down on the amount of time and money needed to complete the project. There are various forms of software testing, and the definitions of smoke testing and sanity testing are hotly contested in the computer community. The chosen style of testing is influenced by the goal being pursued, the software's functioning, and its complexity.

In this blog, we'll examine the subject of what sanity testing is, explain its advantages and practicality, and look at the question of what sanity testing in Software Testing Training entails in terms of its attributes and illustrations.

Sanity testing: what is it?

Multiple source code files make up a software project. As a result, the process of turning the same into an executable programme can be time-consuming. However, it can be done with the aid of "build" software, in which case the procedure is known as "Software Build."

One should consider Sanity Testing as a subset of Regression Testing in order to comprehend what it means in software testing. Sanity testing is carried out whenever the testing team receives a new software build, following small modifications to its functionality or code, to check that the bugs have been fixed, the errors have been corrected, and there have been no new defects added.

Sanity testing is a broad, rapid, and shallow method of software testing that aids in assessing the need for additional testing. It aids in validating an application's functionality without requiring extensive testing. As a result, Sanity examinations frequently lack documentation, are unscripted, and only include the most crucial information. In order to make sure that the new code modifications do not impact the existing functionalities, sanity testing is essential.

What are sanity tests and smoke tests?

After a software build, smoke testing is carried out to make sure that a software application's core capabilities operate without a hitch. It is done even before full Functional or Regression Testing starts. The main goal is to confirm that the crucial capabilities are functioning properly in order to assess the viability of additional testing. Both the smoke test and the sanity test are frequently referred to as substitutes since they both aid in assessing if additional testing is appropriate. The latter, however, examines newly added functionalities like bug patches while the former assists in testing the basic functions that are already in place.

Additionally, keep in mind that Sanity Testing is a variety of Regression Testing, whereas Smoke Testing is a variant of Acceptance Testing, whose objective is to check stability. As you work to comprehend what smoke testing and sanity testing are, keep these distinctions in mind.

Sanity testing characteristics

·         Near the end of a test cycle, sanity testing is carried out following rigorous regression testing.

·         They are typically unscripted and undocumented.

·         They are carried out by testers and serve as filters that determine whether it is possible for builds to go to the next stage of testing.

·         It uses a tight and in-depth testing methodology that concentrates on a small set of functionalities.

·         They are typically carried out manually and are not automated.

·         Sanity testing is also known as cursory testing because it examines an application's functionality following small code modifications.

Sanity testing explained with an example

You will undoubtedly be able to comprehend Sanity Testing better by way of straightforward examples.

Figure 1:

You have created a straightforward web application. Multiple modules for various functionalities would undoubtedly be present in this application. Let's say that after integrating the Captcha API into the signup module, you discover that there is a problem with it. You will attempt to make some changes to the code in order to resolve the problem. To test every module of the programmes again to make sure the functionality that has been changed is functioning as intended is virtually pointless after this, though. Conducting a Sanity Test in this circumstance can assist in verifying the signup module only, saving money and time.

Figure 2:

You've created another programme that has numerous pages, such as the login page, user profile page, create new user page, and so on. The page where new users are created has a registration form where people can fill out their information and submit it. You now want to provide a Preview option so that users may see their completed application before submitting it. After the development team has implemented the required modification, it will be crucial to verify that the newly added feature is functioning as intended. To test every module of the programme, though, would be pointless. Sanity testing can be beneficial for testing a newly added function without interfering with previously tested features.

Sanity Testing Benefits

·         Sanity testing is less expensive than other kinds of testing.

·         It is simple to understand, simple to use, and effective.

·         It doesn't need any scripting or prior documentation.

·         Sanity testing reduces the time and effort required for testing by taking a narrow and in-depth approach and concentrating solely on a few functionalities.

·         It allows for the early discovery of errors and flaws in the software development process itself.

·         It is helpful to draw attention to any compilation or deployment problems.


I assume that by the time this blog post is up, you will have a good understanding of what sanity testing is. It is crucial to comprehend the distinctions between the concepts of smoke testing and Software Testing Course since they are sometimes confused with one another. It is evident that Sanity Testing enables speedy evaluation and is frequently used when a new functionality is implemented or a modification request is made.
