What is Sanity Testing?
Updated Apr 28, 2026
Short answer
A subset of regression testing performed to quickly verify that specific bug fixes or changes work as expected.
Deep explanation
At the junior level, testing is about understanding the fundamental objectives: finding defects and ensuring requirements are met. You must master the distinction between functional and non-functional testing. Quality is not just about the absence of bugs but the presence of value.
Real-world example
Testing a login form: entering correct credentials (positive) and incorrect ones (negative).
