TestNG问题（Selenium Grid）有并行测试吗？-Java 学习之路

当我在appium（Android）中使用Selenium网格运行并行测试脚本时，我遇到了错误 .

Default suite Total tests run: 6, Failures: 0, Skips: 3 Configuration Failures: 1, Skips: 0

堆栈跟踪消息： org.openqa.selenium.SessionNotCreatedException: A new session could not be created. (Original error: Requested a new session but one was in progress) My TestNG xml文件：

<suite name="Default suite" thread-count="4" parallel="tests">
<test name="Nexus">
<Parameters>
<parameter name="platform" value="Nexus"/>
<parameter name="browsername" value="Android"/>
<parameter name="remoteurl" value="http://0.0.0.0:4723/wd/hub"/>
</Parameters>
<classes>
<class name="AppiumTest">
<methods>
<include name="Test1"/>
<include name="Test2"/>
<include name="Test3"/>
</methods>
</class>
</classes>
</test>
<test name="Moto E">
<Parameters>
<parameter name="platform" value="Moto E"/>
<parameter name="browsername" value="Android"/>
<parameter name="remoteurl" value="http://0.0.0.0:4726/wd/hub"/>
</Parameters>
<classes>
<class name="AppiumTest">
<methods>
<include name="Test1"/>
<include name="Test2"/>
<include name="Test3"/>
</methods>
</class>
</classes></suite>

Config.Json文件：

{
"capabilities":
[
{
"browserName":"Nexus",
"version":"5.1.1",
"maxInstances": 1,
"platform":"ANDROID"
}
],
"configuration":
{
"cleanUpCycle":2000,
"timeout":30000,
"proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
"url":"http://0.0.0.0:4723/wd/hub",
"host":"192.168.50.114",
"port": 4723,
"maxSession": 1,
"register": true,
"registerCycle": 5000,
"hubPort": 4448,
"hubHost": "192.168.50.114"
}
}

selenium节点的命令： appium --nodeconfig path/to/json file.

测试脚本：

public class AppiumTest {//静态RemoteWebDriver驱动程序;

@SuppressWarnings("rawtypes")
public static AndroidDriver driver;


@SuppressWarnings("rawtypes")
@org.testng.annotations.BeforeTest

public static void setUp() throws MalformedURLException{

    DesiredCapabilities capabilities=new DesiredCapabilities();
    capabilities.setCapability("deviceName","Nexus");
    capabilities.setCapability("platformName","Android");

    capabilities.setCapability("appPackage","club.apptu.basic.callrecorder");
    capabilities.setCapability("appActivity","MainActivity");
    driver=new AndroidDriver(new URL("http://0.0.0.0:4723/wd/hub"),capabilities);

    driver.manage().timeouts().implicitlyWait(0, TimeUnit.SECONDS);

}

@org.testng.annotations.Test
public void Test1(){
  turnonoff();
  turnonoff();

  //longclick();

 // important();
 // delete();
//  deleterecord();
//  scroll();
//  languagechange();

}
@org.testng.annotations.Test
public void Test2(){

      drawer();
      drawer();

}


@org.testng.annotations.Test
public void Test3(){
  clickonitem();
  play();
  pause();

}

任何建议，将不胜感激 .

我一直在使用Selenium Grid和Appium，并遇到了同样的错误 . 当设备断开连接时，它会突然出现，如果您使用真实设备，请尝试断开连接并重新连接USB并重新启动节点 .

你可以跑
```
adb devices
```
如果列出它们，则不应该出现该错误 .

如需任何进一步的帮助，请发布测试脚本和网格的JSON配置文件 .

希望这可以帮助 .

所以我用于相同目的的设置是：

2个设备的TestNG.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
    <suite name="Suite" parallel="tests" thread-count="2">
        <test name="Nexus 7">
            <parameter name="udid"  value="XXXX" />
            <classes>
                <class name="testNG.TestOne"/>
            </classes>
        </test> <!-- Test -->
        <test name="HTC">
            <parameter name="udid"  value="XXXX" />
            <classes>
                <class name="testNG.TestOne"/>
            </classes>
        </test> <!-- Test -->
   </suite> <!-- Suite -->

在这里，我传递每个设备的UDID，没有必要传递任何其他内容，你传递的URL我认为是一个错误，因为你应该将所有AndroidDrivers传递给Selenium Grid Hub URL并使用这些功能Hub应将测试分配给正确的设备 .

DriverSetup类使用以下方法：

public static AndroidDriver getDriver(String udid) throws MalformedURLException{

String SELENIUM_HUB_URL = "XXXX";
ThreadLocal<AndroidDriver> driver = null;  

DesiredCapabilities capabilities = new DesiredCapabilities();       
capabilities.setCapability("device", udid);
capabilities.setCapability("deviceName", udid);
capabilities.setCapability("udid", udid);
capabilities.setPlatform(Platform.ANDROID);
capabilities.setCapability("browserName", "Chrome");    

try {
    driver = new ThreadLocal<AndroidDriver>();
    driver.set(new AndroidDriver(new URL(SELENIUM_HUB_URL),
            capabilities));
} catch (MalformedURLException e) {
    System.out.println("Tackle Issue with RemoteDriverSetup");
}
driver.get().manage().timeouts()
        .pageLoadTimeout(20L, TimeUnit.SECONDS);
driver.get().manage().timeouts()
        .implicitlyWait(20L, TimeUnit.SECONDS);

return driver.get();
}

您需要更改功能以适合您的项目，但我建议使用UDID作为功能，因为它意味着测试 has 在某个设备上运行 .

通过在控制台中键入 adb devices 找到设备的UDID .

您初始化AndroidDriver时使用Selenium Grid Hub URL，如果您绕过Hub并将测试直接发送到节点，则会丢失Grid并行运行测试的功能 .

我的TestOne类中的BeforeClass方法：

@Parameters({"udid"})
@BeforeClass

public void beforeClass(String udid) throws UnsupportedEncodingException, MalformedURLException, InterruptedException{
System.out.println("Run started for " + udid);
driver = DriverSetup.getDriver(udid);
}

JSON配置文件

{
"capabilities":
[
{
"browserName": "Chrome",
"deviceName": "XXXX",
"device": "XXXX",
"udid":"XXXX",
"version":"4.2",
"maxInstances": 5,
"platform":"ANDROID",
"platformName": "Android"
}
],
"configuration":
{
"cleanUpCycle":2000,
"timeout":10000,
"proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy", 
"url":"http://0.0.0.0:4723/wd/hub",
"maxSession": 5,
"port": 4723,
"host": "0.0.0.0",
"register": true,
"registerCycle": 5000,
"hubPort": 4444,
"hubHost": "localhost"
}
}

我希望这可以帮助您解决问题 .
