Manual Testing
Manual testing is a software testing technique where testers manually execute test cases without using any automation tools, relying on human observation and interaction to identify bugs, usability issues, and functional defects. It involves exploring the application's features, user interfaces, and workflows to ensure they meet specified requirements and provide a good user experience. This approach is essential for evaluating subjective aspects like look-and-feel, and for ad-hoc or exploratory testing scenarios.
Developers should learn manual testing to quickly validate new features, perform exploratory testing to uncover unexpected issues, and ensure user-centric quality before investing in automation. It is particularly useful in early development stages, for usability testing, and in agile environments where rapid feedback is needed. Manual testing also helps in understanding user perspectives and catching edge cases that automated scripts might miss.
