如何在 UWP 中使用 WinAppDriver 等待元素? [英] How do I wait for an element using the WinAppDriver in UWP?

问题描述

我目前正在使用 WinAppDriver 将 UWP 应用的编码 UI 测试迁移到 Appium 和我遇到了这个问题，我等不及某个元素出现了.没有办法像 Microsoft 的编码 UI 测试那样等待元素准备好".

I'm currently migrating my Coded UI Tests for a UWP app to Appium using the WinAppDriver and I have come across the issue, that I can't wait for an element to show up. There is no way to wait for a element to be "ready" as the Coded UI Test from Microsoft did.

在 ClassInitialize 方法中，一切正常(数据在登录视图中输入)并单击登录按钮.触发点击事件后，应用程序会显示一个进度条，直到用户登录.我的问题是登录过程后我无法等待组件.

In the ClassInitialize method everything works fine (data is entered on the login view) and the login button is clicked. After the click event is triggered the app shows a progress bar until the user is logged in. My problem is that I cannot wait for the components after the login process.

我发现了一些代码片段，但是，它们似乎对我不起作用.这是我目前使用的扩展方法:

I have found some code snippets, however, they don't seem to work for me. Here is the extension method I'm currently using:

public static IWebElement WaitForElement(this IWebDriver driver, By by, int timeoutInSeconds)
{
   if (timeoutInSeconds > 0){
      driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(timeoutInSeconds);
      var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(timeoutInSeconds));
      return wait.Until(ExpectedConditions.ElementIsVisible(by));
   }
   return driver.FindElement(by);
}

我还了解到必须设置 Windows 驱动程序的隐式超时:

I have also read that the implicit timeout for the Windows driver has to be set:

session = new WindowsDriver<WindowsElement>(new Uri(WindowsApplicationDriverUrl), appCapabilities);
session.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(60);

并在 WaitForElement 方法中被覆盖，这对我也不起作用.

and overridden in the WaitForElement method, which also didn't work for me.

在点击 WinAppDriver 之前等待元素

[TestMethod]
public void UploadDocuments()
{
   var UploadButton = session.WaitForElement(By.XPath("//Button[@AutomationId='AddDocument']"), 60);
   UploadButton.Click();

   session.FindElementByXPath("//ToolbarWindow32[@AutomationId='1001']").SendKeys(Keys.Control + "a");
   session.FindElementByXPath("//ToolbarWindow32[@AutomationId='1001']").SendKeys(testFilesFolder);

   //session.FindElementByName("Open").Click();
}

在使用 ClassInitialize 完成后，测试通常会在第一行崩溃.所以我想在测试继续之前等待'AddDocument'按钮弹出.

The test usually crashes in the first line after it's finished with the ClassInitialize. So I would like to wait for the 'AddDocument' button to pop up before the test carries on.

如果有人有解决方案，我将不胜感激.谢谢！

If anyone has a solution I'd appreciate the help. Thanks!

推荐答案

您可以像这样实现等待功能:

You can implement wait funcionalities like this:

public WindowsElement GetElementByAutomationID(string automationId, int timeOut = 10000)
{
    WindowsElement element = null;

    var wait = new DefaultWait<WindowsDriver<WindowsElement>>(Driver)
    {
        Timeout = TimeSpan.FromMilliseconds(timeOut),
        Message = $"Element with automationId \"{automationId}\" not found."
    };

    wait.IgnoreExceptionTypes(typeof(WebDriverException));

    try
    {
        wait.Until(Driver =>
        {
            element = Driver.FindElementByAccessibilityId(automationId);
            return element != null;
        });
    }
    catch (WebDriverTimeoutException ex)
    {
        LogSearchError(ex, automationId);
        Assert.Fail(ex.Message);
    }

    return element;
}

您的问题似乎是 appium-dotnet-driver 问题.在 github 上查看这些问题:https://github.com/Microsoft/WinAppDriver/issues/329

Your problem seems to be a appium-dotnet-driver issue. See these issues on github about this: https://github.com/Microsoft/WinAppDriver/issues/329
