Why Sanity Testing is Crucial in Agile Software Testing
In the fast-paced world of Agile Software Testing , ensuring software quality without slowing down development is a top priority. One key practice that helps teams achieve this balance is sanity testing — a focused, high-impact type of testing that quickly verifies whether recent code changes or bug fixes behave as expected. Sanity testing sits within the broader umbrella of software testing and is considered a subset of regression testing. Unlike exhaustive regression or smoke tests that cover broad functionality or overall build stability, sanity testing drills deeply into specific areas affected by recent changes. This makes it an ideal checkpoint in Agile environments where rapid builds and frequent iterations are the norm. In Agile cycles, development teams push new features or bug fixes several times within a sprint. Running full test suites after each tiny change would waste valuable time. Instead, sanity tests act as an early control gate — quickly confirming that the co...
