android – 尝试单击导航按钮时Espresso AmbiguousViewMatcherException

Android 前端之家
前端之家收集整理的这篇文章主要介绍了android – 尝试单击导航按钮时Espresso AmbiguousViewMatcherException，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
测试我正在尝试：进行购买,记下标题,然后返回到主页活动,然后按“home_image”这是一个图像按钮.

我的问题是我无法导航home_image.我按它,我得到一个伪造的重复ID.我相信重复ID是指具有相同ID的不可见片段.为什么在测试开始时不是问题很奇怪.由于文本限制,抱歉不得不截断日志.
我想做的就是直接启动家庭活动,但这个套件只是做一件简单事情的痛苦.即使是滑动命令也会出现此错误！第一次通过所有这些按钮工作,我认为这是浓缩咖啡的一个错误,我需要一个解决方案.

谢谢你的想法！

解决方法

这不是Espresso中的错误.视图层次结构清楚地显示了具有相同ID的两个视图.这可能是由于视图位于ViewPager内部,而ViewPager是一个AdapterView.因此可以预期多个实例.

要解决此问题,请在匹配视图时更具体.仅仅通过ID无济于事.由于主页按钮的其他ImageView不可见,因为它的父级是GONE,您可以简单地匹配：

onView(allOf(withId(..),withEffectiveVisibility(VISIBLE))).perform(click());
