Can you share your experience with manual testing and the approaches you used?

In manual testing, I usually follow these approaches:

• Understanding requirements: carefully studying specifications and user scenarios.
• Test planning: creating checklists and test cases to cover all functional and non-functional aspects.
• Step-by-step execution: sequentially performing tests, recording results and bugs found.
• Regression: repeating tests after fixing bugs to ensure no new issues have arisen.
• Using different devices and environments: testing the application on various platforms and configurations.

For example, when testing a mobile application, I checked the correctness of navigation, error handling, network operation under different conditions, as well as UI on different screen sizes.
