Manual Validation
Manual validation is a software testing approach where human testers execute test cases without automation tools, relying on their intuition and domain knowledge to identify defects. It involves hands-on interaction with software applications to verify functionality, usability, and performance against requirements. This method is essential for exploratory testing, user experience evaluation, and scenarios where automated testing is impractical or too costly.
Developers should learn manual validation to complement automated testing, especially for usability testing, ad-hoc scenarios, and early-stage development where requirements are fluid. It is crucial for identifying subtle bugs, such as visual inconsistencies or user interface issues, that automated scripts might miss, and for validating complex business logic in domains like finance or healthcare where human judgment is irreplaceable.
