使用Javascript连接到Winappdriver中正在运行的进程

Question

我对JS/Winappdriver相当陌生。

我尝试测试的应用程序是来自的一个基于windows的"单击一次"应用程序。Net，所以我必须从IE转到一个网站，然后点击"安装"。这将打开应用程序。

一旦应用程序运行，我就无法在使用JavaScript的同时连接应用程序来执行UI交互。

使用C#，我在进程中循环，寻找进程名称，获取窗口句柄，将其转换为十六进制，将其添加为一种功能，并创建驱动程序——这很有效。下面的示例代码，

public Setup_TearDown()
{
string TopLevelWindowHandleHex = null;
IntPtr TopLevelWindowHandle = new IntPtr();
foreach (Process clsProcess in Process.GetProcesses())
{
if (clsProcess.ProcessName.StartsWith($"SomeName-{exec_pob}-{exec_env}"))
{
TopLevelWindowHandle = clsProcess.Handle;
TopLevelWindowHandleHex = clsProcess.MainWindowHandle.ToString("x");
}
}
var appOptions = new AppiumOptions();
appOptions.AddAdditionalCapability("appTopLevelWindow", TopLevelWindowHandleHex);
appOptions.AddAdditionalCapability("ms:experimental-webdriver", true);
appOptions.AddAdditionalCapability("ms:waitForAppLaunch", "25");
AppDriver = new WindowsDriver<WindowsElement>(new Uri(WinAppDriverUrl), appOptions);
AppDriver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(60);
}

如何在Javascript中执行此操作我似乎找不到任何代码示例。基于这个repo的一个例子，我在JS中尝试了以下操作，以找到要锁定的进程，但没有成功。

import {By2} from "selenium-appium";
// this.appWindow = this.driver.element(By2.nativeAccessibilityId('xxx'));
// this.appWindow = this.driver.element(By2.nativeXpath("//Window[starts-with(@Name,"xxxx")]"));
// this.appWindow = this.driver.elementByName('WindowsForms10.Window.8.app.0.13965fa_r11_ad1');
// thisappWindow = this.driver.elementByName('xxxxxxx');
async connectAppDriver(){
await this.waitForAppWindow();
var appWindow = await this.appWindow.getAttribute("NativeWindowHandle");
let hex = (Number(ewarpWindow)).toString(16);
var currentAppCapabilities =
{
"appTopLevelWindow": hex,
"platformName": "Windows",
"deviceName": "WindowsPC",
"newCommandTimeout": "120000"
}
let driverBuilder = new DriverBuilder();
await driverBuilder.stopDriver();
this.driver = await driverBuilder.createDriver(currentEwarpCapabilities);
return this.driver;
}

我在Winappdriver 中不断收到此错误

{"status":13,"value":{"error":"unknown error","message":"An unknown error occurred in the remote end while processing the command."}}

我也在这里开了这张票。

这似乎是一件很容易做的事，但我想不通。

我可以使用任何节点包来轻松获得顶级窗口句柄？

我对如何在使用JavaScript for Winappdriver时解决这个问题持开放态度。

希望这能帮助一些人，

通过使用C#创建一个exe来绕过这个问题，该exe生成了基于进程名称连接的应用程序的十六进制，看起来像这样。

public string GetTopLevelWindowHandleHex()
{
string TopLevelWindowHandleHex = null;
IntPtr TopLevelWindowHandle = new IntPtr();
foreach (Process clsProcess in Process.GetProcesses())
{
if (clsProcess.ProcessName.StartsWith(_processName))
{
TopLevelWindowHandle = clsProcess.Handle;
TopLevelWindowHandleHex = clsProcess.MainWindowHandle.ToString("x");
}
}
if (!String.IsNullOrEmpty(TopLevelWindowHandleHex))
return TopLevelWindowHandleHex;
else
throw new Exception($"Process: {_processName} cannot be found");
}

从JS调用它以获得顶级窗口句柄的十六进制，就像这样，

async getHex () {
var pathToExe =await path.join(process.cwd(), "features\support\ProcessUtility\GetWindowHandleHexByProcessName.exe");
var pathToDir =await path.join(process.cwd(), "features\support\ProcessUtility");
const result = await execFileSync(pathToExe, [this.processName]
, {cwd: pathToDir, encoding: 'utf-8'}
, async function (err, data) {
console.log("Error: "+ err);
console.log("Data(hex): "+ data);
return JSON.stringify(data.toString());
});
return result.toString().trim();
}

使用十六进制连接到这样的应用程序，

async connectAppDriver(hex) {
console.log(`Hex received to connect to app using hex: ${hex}`);
const currentAppCapabilities=
{
"browserName": '',
"appTopLevelWindow": hex.trim(),
"platformName": "Windows",
"deviceName": "WindowsPC",
"newCommandTimeout": "120000"
};
const appDriver = await new Builder()
.usingServer("http://localhost:4723/wd/hub")
.withCapabilities(currentAppCapabilities)
.build();
await driver.startWithWebDriver(appDriver);
return driver;
}

解决方案：在WebDriverJS(selenium/appium使用(中，使用getDomAttribute而不是getAttribute。花了几个小时才找到：(

element.getAttribute("NativeWindowHandle")
POST: /session/270698D2-D93B-4E05-9FC5-3E5FBDA60ECA/execute/sync
Command not implemented: POST: /session/270698D2-D93B-4E05-9FC5-3E5FBDA60ECA/execute/sync
HTTP/1.1 501 Not Implemented

---

let topLevelWindowHandle = await element.getDomAttribute('NativeWindowHandle')
topLevelWindowHandle = parseInt(topLevelWindowHandle).toString(16)
GET /session/DE4C46E1-CC84-4F5D-88D2-35F56317E34D/element/42.3476754/attribute/NativeWindowHandle HTTP/1.1
HTTP/1.1 200 OK
{"sessionId":"DE4C46E1-CC84-4F5D-88D2-35F56317E34D","status":0,"value":"3476754"}
and topLevelWindowHandle have hex value :)
