📘Easy summary
Advanced testing and debugging techniques help create reliable and efficient applications; they go beyond basic error fixing, identify hidden problems, improve performance and user satisfaction, and make future maintenance easier. Testing and debugging ensure applications work correctly under all conditions and detect and remove errors before the software is released. Testing checks whether an application meets its requirements, ensures all functions produce correct results, reduces the risk of crashes or incorrect outputs, and verifies that changes do not break existing features. Debugging locates the cause of errors and fixes them efficiently. Together they increase reliability and user confidence.
⭐Key points
- Testing = check program gives expected output.
- Debugging = find and fix bugs.
- Both before release.
