Manual Testing involves a human tester executing test cases without automation — used to validate user experiences, edge cases, and complex workflows.
While automated testing offers speed, manual testing brings context and empathy. It’s essential for exploratory testing, usability assessments, and cases where intuition matters more than scripts.
Manual QA testers often work alongside developers and automation engineers to ensure critical flows behave as expected, especially before major launches or when testing across real devices and browsers.
It remains a valuable layer in any quality assurance strategy — particularly for UI/UX validation and one-off test cases.
