Usability testing is applicable to all stages of the online shopping system, including:

**New system development phase:** During the system development process, usability testing is conducted to ensure that the design and functionality of the user interface meet user needs.
**System updates and feature enhancements:** When the system is updated, new features are added, or existing features are modified, usability testing is conducted to evaluate the improvement of the user interface.
**Mobile application development:** For mobile shopping applications, conduct usability testing to ensure users have a good experience on different mobile devices.
**User Interface Redesign:** When undertaking a user interface redesign, conduct usability testing to verify the usability and user satisfaction of the new design.

3. Common technologies and tools:

**User research and feedback collection:** Obtain user feedback and opinions through user research, questionnaires, user interviews and other methods.
**Task scenario design: **Develop typical user task scenarios to simulate the user's specific operation process in the system.
**User behavior recording:** Use tools to record users' operating behaviors and reactions during the test process, such as eye tracking, screen recording, etc.
**User interface evaluation:** Use evaluation tools and methods, such as heuristic evaluation, usability rating scales, user satisfaction questionnaires, etc., to evaluate and quantitatively analyze the user interface.
