无法在使用 Appium 和 C# 的 Android 模拟器的浏览器中找到元素 [英] Unable to find an element in Browser of the Android emulator using Appium and C#

问题描述

我想使用 c# 和 Appium 在 Android 模拟器上自动化移动网站测试.我想在开始时自动化一个简单的测试场景:
1. 启动浏览器
2. 查找元素
3.清除它
4. 发送密钥

I want to automate mobile web site testing on Android emulator using c# and Appium. There is a simple test scenario I want to automate for the start:
1. Start Browser
2. Find an element
3. Clear it
4. Send keys

我的第二步有问题.每次 MSTest 尝试在下面的代码中执行 FindElementById 行时，我都会收到错误消息:无法使用给定的搜索参数在页面上找到元素."

I've got a problem with the second step. Every time MSTest tries to execute FindElementById line in the code below, I get the error: "An element could not be located on the page using the given search parameters."

[TestClass]
public class UnitTest1
{
    private DesiredCapabilities _capabilities;
    private AndroidDriver _driver;

    public void InitializeDriver()
    {
        Console.WriteLine("Connecting to Appium server");
        _capabilities = new DesiredCapabilities();

        _capabilities.SetCapability("deviceName", "test_02");
        _capabilities.SetCapability(CapabilityType.BrowserName, "Chrome");
        _capabilities.SetCapability(CapabilityType.Version, "5.0.1");
        _capabilities.SetCapability(CapabilityType.Platform, "Android");

        //Application path and configurations
        _driver = new AndroidDriver(new Uri("http://127.0.0.1:4723/wd/hub"), _capabilities);
    }

    [TestMethod]
    public void TestMethod1()
    {
        InitializeDriver();

        var element = _driver.FindElementById("com.android.browser:id/url");
        element.Clear();
        element.SendKeys(@"http://stackoverflow.com/");
    }
}

我从 UIAutomator 获得的方法的输入字符串，如下所示.

Input string for the method I've got from UIAutomator that is shown below.

我为 FindElementById 输入法尝试了几种组合:
com.android.browser:id/url"
ID/网址"
网址"
但没有运气.

I tried several combinations for the FindElementById input method:
"com.android.browser:id/url"
"id/url"
"url"
but no luck.

我的环境:
视窗 8.1
Appium 1.3.4.1
ChromeDriver 2.14.313457
Android 设备监视器 24.0.2

My environment:
Windows 8.1
Appium 1.3.4.1
ChromeDriver 2.14.313457
Android Device Monitor 24.0.2

推荐答案

抱歉误导！！！在浏览器中测试 Web 应用程序的情况下，元素应该像网页上的通常元素一样(而不是像 android.widget.EditText 和 android.widget.Button 这样的一些类).因此，例如尝试以下操作，您将看到一些结果:

Sorry for misleading !!! In case of testing web apps in browser the elements should be located as usual elements on the web page ( not as some classes like android.widget.EditText and android.widget.Button). So try for example the following and you will see some result:

    var element = _driver
            .findElementByXPath("//input[@id='lst-ib']");

要获取定位器，您应该在桌面上运行浏览器，打开页面并使用一些工具/扩展程序，例如 Firefox 中的 Firebug 或 Chrome 浏览器中的 Firebug Lite.

To get locators you should run the browser on your desktop, open the page and use some tools/extensions like Firebug in Firefox or Firebug Lite in Chrome browser.
