假设我正在创建一个类似短信应用的Android应用程序,要求如下:
对于我的测试案例,以下是规格:
- 用户可以收到多个通知,每个通知具有int类型的动态ID。
- 当选择通知时,它会加载一个活动,显示相应的消息(即短信)。
- 所选的单个通知应自动消失。
对于我的测试案例,以下是规格:
- 通知最终将从服务生成,现在它们是在测试用户按下按钮时产生的。
- 当选择通知时,被调用的活动显示消息,然后尝试解除通知。 (为了更好地看到效果)
- 选择第一个通知时,正确。 通知已解除。
- 当选择每个连续的通知时,会显示第一个通知的ID,并且不会解除任何通知。
- 我是Java初学者,更习惯于脚本语言(如Perl、PHP等):)
