1.可用性测试：
可用性测试是一种测试方法，用于衡量软件应用程序的易用性和用户友好性。这也称为用户体验(UX)测试。它由充当潜在最终用户的一群人执行。可用性测试主要关注用户如何轻松访问应用程序的所有功能而不会遇到任何问题。它主要在设计的初始阶段执行。
2.启发式评估：
启发式评估是彻底评估/评估的过程，在此过程中，专家用来衡量用户界面的可用性。可用性可以定义为特定用户可以轻松使用特定设计或说界面而不会遇到任何问题。
可用性测试和启发式评估之间的区别：
| Usability testing | Heuristic evaluation |
|---|---|
| Performed by the group of non-professional users. | Performed by experts with relevant skills. |
| Helps to identify the real issues. | Helps to identify the potential/hidden issues. |
| Specific or limited tasks are performed by the user. | Predefined guidelines & checklists are defined and evaluators have to stick with that. |
| ‘Screen-by-screen’ approach is used by testers to test the system. | Whole system is evaluated by experts in a systematic manner. |
| Helps to improve the functionality of the programs. | Helps to improve the overall user experience by thorough evaluation. |
| It is costly because it involves a lot of user participation. | It is cheaper and faster than conducting full-blown usability testing. |
