在编码的UI测试中仅知道部分窗口标题时查找窗口 [英] Finding a window when only part of the window title is known in Coded UI Tests

问题描述

我正在为其编写编码的UI测试的应用程序有一个窗口，其中窗口标题的一部分基于为临时文件生成的随机文件名，因此该测试只能知道窗口标题的静态部分。

The application I am writing coded UI tests for has a window where part of the window title is based on a random filename generated for a temporary file, so the test can only know the static part of the window title.

有时，当没有其他窗口打开时，测试运行良好。但是，当其他窗口打开时，这有点问题。如果其他窗口具有类似的控件，则测试选择使用的窗口是不可预测的。

Occasionally, when no other windows are open, the test runs fine. It is a bit problematic when other windows are open, however. If the other windows have similar controls, which window the test picks to work in is unpredictable.

推荐答案

我已经缩小了范围为此：在搜索控件时，编码的UI测试使用搜索属性和控件的树状结构。如果找不到完全匹配的内容，则会找到一个紧密匹配的内容（因此找不到确切的窗口标题名称，它将排除该名称，并继续搜索与任何其他给定属性匹配的窗口），这就是它可以与控件一起使用的原因在其他窗口中。

I've narrowed it down to this: When searching for a control, the Coded UI Test uses search properties and a tree-like structure of controls. If it can't find an exact match it finds a close match (so it can't find the exact window title name, it excludes that and keeps searching for a window that matches any other given properties) which is why it works with controls in other windows.

该解决方案实际上是为其提供更多搜索属性。我使用的一种方法是使用 PropertyExpression 添加属性并通过 PropertyExpressionOperator.Contains 。

The solution is really to give it more search properties to work with. One method I use is to add a property using a PropertyExpression and pass it PropertyExpressionOperator.Contains.

作为示例，我记录了打开MS Word并关闭它的过程。这将在UIMap中生成一个控件，并且在其构造函数中如下所示：

As an example, I recorded opening MS Word and closing it. This generates a control in the UIMap, and in its constructor is the following:

this.SearchProperties[WinWindow.PropertyNames.Name] = "Document1 - Microsoft Word";
this.SearchProperties[WinWindow.PropertyNames.ClassName] = "OpusApp";

相反，第一行应为：

this.SearchProperties.Add(new PropertyExpression(WinWindow.PropertyNames.Name, "Microsoft Word", PropertyExpressionOperator.Contains));
