Sanity Testing vs Regression Testing: Key Differences

Sanity testing and regression testing are two important types of software testing that occur during the Software Development Life Cycle (SDLC). Sanity testing is a quick test performed after minor changes to ensure stability for further testing, while regression testing validates changes made to the software without breaking anything. Both tests have different purposes, scopes, and frequencies. Sanity testing focuses on specific areas or features of the software application, whereas regression testing covers the entire system, including both old and new functionalities. Regression testing is more extensive and time-consuming due to broader coverage, while sanity testing is quicker and less time-consuming. Automation tools like Selenium, Playwright, Cypress, and Appium can be used for performing sanity tests, with LambdaTest being a popular cloud-based testing platform that supports various automation frameworks.
