c# - 无法直接使用 TestStack.White 单击按钮

Question

我正在尝试单击外部 Windows 应用程序上的按钮。下面的代码成功地找到了元素，使父窗口成为焦点，然后“手动”点击按钮

这没问题...

Process tProcess = Process.GetProcesses().FirstOrDefault(x => x.MainWindowTitle.StartsWith("MainWindowName"));
if (tProcess != null)
{
    TestStack.White.Application application = TestStack.White.Application.Attach(tProcess.Id);
    var tWindow = application.GetWindow(SearchCriteria.ByAutomationId("SubWindowName"), InitializeOption.NoCache);
    SearchCriteria searchCriteria = SearchCriteria.ByAutomationId("btnCalibrate");
    var calibrateBtn = tWindow.Get<TestStack.White.UIItems.Button>(searchCriteria);
    tWindow.Focus();
    var clickablePoint = calibrateBtn.AutomationElement.GetClickablePoint();
    Mouse.Instance.Click(clickablePoint);
}

问题是 Mouse.Instance.Click(clickablePoint); 移动了光标，理想情况下我不想移动光标。

我的初始代码尝试使用以下代码直接单击按钮

Process tProcess = Process.GetProcesses().FirstOrDefault(x => x.MainWindowTitle.StartsWith("MainWindowName"));
if (tProcess != null)
{
    TestStack.White.Application application = TestStack.White.Application.Attach(tProcess.Id);
    var tWindow = application.GetWindow(SearchCriteria.ByAutomationId("SubWindowName"), InitializeOption.NoCache);
    SearchCriteria searchCriteria = SearchCriteria.ByAutomationId("btnCalibrate");
    var calibrateBtn = tWindow.Get<TestStack.White.UIItems.Button>(searchCriteria);
    tWindow.Focus();
    calibrateBtn.Click();
}

但这每次都会出现以下错误

TestStack.White.AutomationException
  HResult=0x80131500
  Message=Cannot perform action on Button. AutomationId:btnCalibrate, Name:Calibrate, ControlType:button, FrameworkId:WinForm, 
  Source=TestStack.White
  StackTrace:

   at BetfairStreamingAPI.RadForm1.radLabelBetTime_Click(Object sender, EventArgs e) in D:

有谁知道为什么第二种方法会抛出这个错误，是否可以解决这个问题，这样就可以在不手动移动光标的情况下单击按钮？

这个特定问题的解决方案似乎是使用 .RaiseClickEvent() 而不是 .Click()

下面的代码有效

Process tProcess = Process.GetProcesses().FirstOrDefault(x => x.MainWindowTitle.StartsWith("MainWindowName"));
if (tProcess != null)
{
    TestStack.White.Application application = TestStack.White.Application.Attach(tProcess.Id);
    var tWindow = application.GetWindow(SearchCriteria.ByAutomationId("SubWindowName"), InitializeOption.NoCache);
    SearchCriteria searchCriteria = SearchCriteria.ByAutomationId("btnCalibrate");
    var calibrateBtn = tWindow.Get<TestStack.White.UIItems.Button>(searchCriteria);

    calibrateBtn.RaiseClickEvent();
}

从 White 文档中并不能完全清楚何时/为什么这是首选。我在此链接上找到了方法 RaiseClickEvent https://github.com/TestStack/White/commit/7b6d4dbc0008c3375e2ebf8810c55cb1abf91b60
