Establishing the quality and performance of a product is very important in the domain of software development. To reach this goal, Sanity Testing is used, a sanity check, or verification testing of a build. This kind of testing involves the evaluation of a single build of software to verify that its core components are working appropriately even after several trivial changes or bug fixes take place. Technically speaking, sanity testing can be thought of as a quick reliability check of whether the software still operates as expected and is not affected by the negative impact of recent changes.

    By performing regression testing, developers can quickly track any possible difficulties or rejections that may have arisen during the development process. While this proactive approach is essential to the maintenance of the software as a whole, it ultimately leads to a successful user experience by satisfying the customers as well.

    Importance of Sanity Testing

    1. Identifying Critical Issues: 

    Sanity testing gives us the ability to see any critical problems that might have arisen by doing some recent module changes or fixing defects.

    1. Time and Cost Efficiency: 

    Efforts can be monitored by concentrating on correlated functions, and sanity can be achieved within a short duration when compared to the regression testing of applications.

    1. Enhancing User Experience: 

    Implementing basic elements of applications that perform as intended helps users go through an easier time.

    Correct Implementation of Sanity Testing

    1. Define clear objectives: 

    Start by setting clear goals and performance criteria for the sanity testing stage. Identify which functionalities are fundamental and which should be treated as a top priority and tested accordingly.

    1. Select Relevant Test Cases: 

    Identify the test cases that feature basic functions that have recently been affected by change. Identify and run the test criteria based on their influence on the software that is tied to its central performance.

    1. Execute Tests Methodically: 

    Choose to select tests carefully and concentrate on the most important areas, for example, user authentication, main features, and test cases that probe many workflows and the whole functionality.

    1. Document and Analyze Results: 

    Record the test results comprehensively, illustrating both the problems and failures encountered during the testing. Evaluate these results and establish the degree of readiness and stability for the software build.


    To sum it up, sanity testing, also known as the sanity check or build verification testing, is the first stage of software testing, which is designed to quickly check whether the function remains the same after minor changes or corrections. The well-being of the software depends on it, and the level of user satisfaction gets improved.

    We can say that sanity testing is surely a key aspect of making software stable and functioning appropriately after a small change or the fixing of a bug. Through the approach of concentration on fundamental functions and systemic testing, errors can be quickly detected and made easy for users to use. Now you know what is sanity testing, it should be approached accurately to launch services and products of good quality.
