我正在尝试运行录制的测试用例并且它给我这个错误:(

我无法理解这一点。

请帮忙。

Answer 1

看起来您录制的UI组件的属性已更改，因此无法执行录制的操作。验证组件的搜索属性是否仍与录制时相同。

Answer 2

请查看堆栈跟踪中显示的以下行：

Microsoft.VisualStudio.TestTools.UITesting.Mouse.
Click(UITestControl control, Point relativeCoordinate)

这意味着CodedUI正在尝试使用屏幕上的特定点单击控件。由于某种原因，它无法找到它想要点击的控件。也许这个特定点上没有按钮。最有可能的是，当前显示设备的屏幕分辨率与用于记录这些测试的显示设备的屏幕分辨率不同。

编码的UI - 播放无法找到具有给定搜索属性的控件
