Sanity testing in software development is a crucial practice that ensures the core functionalities of an application are working properly before performing more in-depth testing. It is often carried out after receiving a new build to verify that the most important features of the software are functioning as expected. This form of testing is not intended to be exhaustive, but rather, it focuses on quickly identifying showstopper issues and confirming that the software is stable enough to proceed with more comprehensive testing like functional and regression tests.

In this article, we will explore the significance of sanity testing in software development, its methodology, benefits, and how it integrates into the overall software testing life cycle. Additionally, we will discuss some of the best tools available to assist with sanity testing, including Testomat.io, a comprehensive test management platform that helps streamline the testing process.

What is Sanity Testing in Software Development?

Sanity testing is a type of software testing performed to check if a particular function or part of the software is working correctly after a new build or modification. Unlike smoke testing, which verifies whether the software build is stable enough for further testing, sanity testing focuses on verifying that specific functionalities perform as expected, without deep-diving into the details.

Sanity testing is typically used when there are minor changes to the application, such as bug fixes or updates to particular features. The goal is to quickly assess if those changes introduced any significant problems that would prevent further testing or usage.

Why is Sanity Testing Important?

1. Quick Identification of Critical Issues: Sanity testing helps detect critical issues early, saving time and resources by preventing the need for extensive testing on unstable software builds. This quick check ensures that the build is ready for more detailed testing.

2. Time-Saving: Since sanity tests are narrow and focused, they are much faster to execute compared to more exhaustive testing techniques. This is especially important in Agile environments where quick feedback on software changes is essential.

3. Improved Efficiency: By addressing core functionality issues upfront, sanity testing allows QA teams to focus on the more complex aspects of the application in subsequent testing phases. It improves overall efficiency by preventing unnecessary delays in testing.

4. Prevents Wasted Effort: Performing sanity testing ensures that developers do not waste time on testing areas that may not even be functional. It prevents unnecessary testing on an unstable system, saving time for both developers and testers.

Sanity Testing Process: Steps to Follow

The process of conducting sanity testing is relatively straightforward and typically involves the following steps:

1. Understanding the Changes: Before performing sanity testing, it is essential to understand what changes have been made to the build. This could include new features, bug fixes, or updates to existing features.

2. Choosing Key Areas to Test: Based on the changes made, testers identify the key areas of the application that are most likely to be affected. These areas are tested to ensure the essential functionality is still intact.

3. Performing the Tests: The testers perform basic functional tests to validate that the software works as expected. They focus on critical paths, such as login, payment processing, and basic navigation, to confirm there are no major issues.

4. Logging Issues: Any issues discovered during sanity testing are logged in a bug-tracking tool and passed to the development team for resolution.

5. Making Decisions: If no major issues are found, the build is deemed stable, and further testing can proceed. If critical issues are found, the build is rejected, and further development is required.

Sanity Testing vs. Smoke Testing

Though often confused, sanity testing and smoke testing are two distinct types of testing with different purposes. Here's how they differ:

1. Smoke Testing: This is a high-level test conducted to check if the software build is stable enough for more detailed testing. It involves testing the most basic and essential functions of the software to ensure it’s not completely broken.

2. Sanity Testing: This is a more focused test that is carried out to validate specific functionality or fixes in a particular section of the application after a new build. It is more specific than smoke testing and is performed after the build has passed smoke testing.

Benefits of Sanity Testing in Software Development

Sanity testing provides numerous advantages to the software development and testing process:

1. Reduced Testing Time: By focusing only on core functionalities, sanity tests are quick and efficient, allowing the testing process to proceed rapidly.

2. Early Detection of Issues: It helps in identifying critical problems early in the software development life cycle, reducing the likelihood of discovering serious issues during later testing phases.

3. Enhanced Software Stability: Since sanity tests focus on the application’s core components, they ensure the system remains stable and usable, even after introducing changes or fixes.

4. Increased Test Coverage: With its focus on the essential features, sanity testing ensures that the most critical parts of the software are always functioning as expected, improving the overall quality of the application.

Tools for Sanity Testing in Software Development

To streamline sanity testing and integrate it efficiently into the development process, various testing tools are available. Here are some of the top tools for sanity testing in software development:

1. Testomat.io: A comprehensive test management platform that simplifies the planning, execution, and tracking of sanity tests. It integrates seamlessly into CI/CD pipelines, offering features that help ensure that critical application functionalities are always thoroughly tested.

2. Selenium: Selenium is a widely-used testing tool for automating web applications. It can be used for sanity testing by automating basic functionality checks across browsers.

3. Jenkins: While Jenkins is primarily a CI/CD tool, it can be used to automate the execution of sanity tests as part of the continuous integration process, ensuring that critical features are always validated with each build.

4. TestComplete: This automated testing platform provides robust features for creating and executing automated sanity tests on desktop, web, and mobile applications, helping to accelerate the testing process.

5. Katalon Studio: Katalon Studio is a powerful test automation solution that can be used for sanity testing. It supports both web and mobile testing and provides an easy-to-use interface for creating and executing test scripts quickly.
