Have you ever heard of "sanity" in software testing? What does it mean, and why is it crucial? How did it originate in relation to regression testing?
As a project manager or team lead, it's essential to understand not only how to use sanity testing but also when to apply it. Sanity testing is a valuable tool, similar to regression testing, due to their shared characteristics and ultimate objectives. This is why project managers should understand the distinctions between each method to deploy a test team effectively and provide them with the appropriate tools, thereby avoiding project delays and budget overruns.
Unlocking Sanity Testing: Its Essence and Guidelines for Effective Implementation
This method assesses the product's quality to determine its readiness for further testing. As a subset of regression testing, it examines various aspects. The primary objective is to evaluate the program's performance after functionality enhancements and changes. The focus is not on detecting specific errors but on analyzing the system's behavior after fixing previously identified errors.
This testing approach saves time by alerting developers to subpar product quality, thereby reducing unnecessary testing efforts. To learn more about the benefits of sanity testing, check out this article on t8tech.
Although it may seem straightforward at first glance, sanity testing has its unique challenges, like any other testing type. QA experts share their insights on how to perform this testing with maximum efficiency:
- Avoid creating test cases, as the testing process is largely intuitive;
- Identify new functional elements, amendments, or fixed bugs;
- Verify that newly applied changes do not compromise the program's proper performance;
- Conduct random checks of related functions to examine their operation;
- After completing the previous steps, proceed to planned testing.
The Rationale Behind Sanity Testing
What if modified code affects the entire system's functionality? What if failures arise with each subsequent amendment?
This is where sanity testing comes into play, saving your efforts. Here are the most compelling reasons to utilize this testing type:
- Time-Saving. Sanity testing saves time by identifying issues early, allowing for quick fixes and reducing unnecessary testing efforts.
- Effort Reduction. Sanity testing prevents unnecessary actions by determining whether additional tests are required, eliminating extra efforts and providing more time for the test team.
- External Issue Identification. Sanity testing reveals deployment-related problems, such as inaccurate user interfaces or missing critical features.
- Rapid Decision-Making. Sanity testing quickly determines the product's status, predicting further steps and enabling rapid decision-making.
