本文介绍了Selenium 使用 Java:启动 Hub 服务器并向 Hub 注册节点的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我是 selenium 的新手，我一直在尝试启动 Selenium Hub 并使用 java 将节点添加到 Hub.我已经使用命令提示符启动它，但我希望它自己发生.我能够启动集线器，但不知道如何添加节点.

以下是我启动集线器的代码:

import org.openqa.grid.internal.utils.configuration.GridHubConfiguration;导入 org.openqa.grid.internal.utils.configuration.GridNodeConfiguration；导入 org.openqa.grid.web.Hub;公共类 StartHub {public static void main(String[] args) 抛出异常 {//TODO 自动生成的方法存根GridHubConfiguration configHub = new GridHubConfiguration();configHub.host = "本地主机";configHub.port = 8060;//GridNodeConfiguration configNode = new GridNodeConfiguration();//configNode.host = configHub.host;//configNode.port = 5300;集线器集线器 = 新集线器(configHub)；//configNode.getHubHost();集线器开始()；//System.out.println(configNode.getRemoteHost());//hub.stop();}}

如何添加节点?

解决方案

Selenium-Grid 服务器版本 2.x.x 配置.

他们的包裹清单

« org.openqa.grid.internal.utils.GridHubConfiguration;« org.openqa.selenium.server.SeleniumServer;

HUB Grid HUB 作为独立服务器运行:Hub 是一个中心点，它在多个节点机器上分发测试，这些节点机器注册到它以并行执行.

使用 GRID HUB 服务器:

  • 将您的测试分布在多台机器或虚拟机 (VM) 上.
  • 您想连接到远程计算机，该计算机具有当前计算机上没有的特定浏览器版本.

启动 HUB 服务器

public class Grid_HUBServer {public static String HUBIP = GRIDINFO.HOSTIP.toString();公共静态整数 HUBPORT = 4444;静态字符串分隔符 = "\n------------------------\n";公共静态无效集线器服务器(){尝试 {GridHubConfiguration gridHubConfig = new GridHubConfiguration();gridHubConfig.setHost(HUBIP);gridHubConfig.setPort( HUBPORT );gridHubConfig.setNewSessionWaitTimeout(50000);File JOSNFile = new File(System.getProperty("user.dir")+"/gridHub.json");gridHubConfig.loadFromJSON(JOSNFile.toString());集线器集线器 = 新集线器(gridHubConfig)；集线器开始()；System.out.println("节点应该注册到" + hub.getRegistrationURL());System.out.format("%s 作为网格中心运行:%s\n" +"控制台 URL : %s/grid/console \n", separator,separator,hub.getUrl());System.out.println("请输入停止服务.");System.in.read();System.in.read();集线器停止()；} 捕获(异常 e){e.printStackTrace();}}公共静态无效主(字符串 [] args){集线器服务器()；}}

NODE [RC] 必须通过此 URL - IP:Port//grid/register 向 HUB 发布请求才能向其注册.

public class Grid_NODEServer extends Grid_HUBServer {静态整数节点端口 = 5555；static String PROXYCLASS = "org.openqa.grid.selenium.proxy.DefaultRemoteProxy";公共静态无效节点服务器(){尝试 {System.setProperty(ChromeDriverService.CHROME_DRIVER_EXE_PROPERTY, CHROME_DRIVER_EXE);System.setProperty(InternetExplorerDriverService.IE_DRIVER_EXE_PROPERTY, IE_DRIVER_EXE);注册请求请求 = 新注册请求();request.setRole( GridRole.NODE );File JOSNFile = new File(System.getProperty("user.dir")+"/registerNode.json");request.loadFromJSON(JOSNFile.toString());映射<字符串，对象>configuration = new HashMap();URL remoteURL = new URL(String.format("http://%s:%d", HUBIP, HUBPORT) );System.out.println("远程地址:"+remoteURL);configuration.put(RegistrationRequest.AUTO_REGISTER, true);configuration.put(RegistrationRequest.HUB_HOST, HUBIP);configuration.put(RegistrationRequest.HUB_PORT, HUBPORT);configuration.put(RegistrationRequest.REMOTE_HOST, remoteURL);configuration.put(RegistrationRequest.PORT, NODEPORT);configuration.put(RegistrationRequest.PROXY_CLASS, PROXYCLASS);configuration.put(RegistrationRequest.MAX_SESSION, 1);//configuration.put(RegistrationRequest.CLEAN_UP_CYCLE, 2000);//configuration.put(RegistrationRequest.MAX_INSTANCES, 1);request.setConfiguration( 配置 );GridNodeServer node = new SeleniumServer( request.getConfiguration() );SelfRegisteringRemote remote = new SelfRegisteringRemote( request );remote.setRemoteServer(节点);remote.startRemoteServer();System.out.format("Selenium Grid 节点已启动并准备注册到集线器" +"%s 作为网格节点运行: %s ", separator,separator);remote.startRegistrationProcess();System.out.println("请输入停止服务.");System.in.read();System.in.read();remote.stopRemoteServer();} 捕获(异常 e){e.printStackTrace();}}公共静态无效主(字符串 [] args){节点服务器()；}}

Selenium-Grid - HUB 的 JSON 配置文件节点是 gridHub.json、registerNode.json 进行实例化.

I am new to the selenium and I have been trying to start Selenium Hub and adding the node to the Hub using java. I have started it using command prompt but I want it to happen on its own. I am able to start the Hub but have no Idea how to add the Node.

Following is my code to start the Hub:

import org.openqa.grid.internal.utils.configuration.GridHubConfiguration;
import org.openqa.grid.internal.utils.configuration.GridNodeConfiguration;
import org.openqa.grid.web.Hub;

public class StartHub {

    public static void main(String[] args) throws Exception {
        // TODO Auto-generated method stub
        GridHubConfiguration configHub = new GridHubConfiguration();
        configHub.host = "localhost";
        configHub.port = 8060;

        //GridNodeConfiguration configNode = new GridNodeConfiguration();
        //configNode.host = configHub.host;
        //configNode.port = 5300;

        Hub hub = new Hub(configHub);
        //configNode.getHubHost();
        hub.start();

        //System.out.println(configNode.getRemoteHost());

        //hub.stop();
    }

}

How to add a Node going forward ?

解决方案

Selenium-Grid Server Version 2.x.x configuration.

Their Packages list

« org.openqa.grid.internal.utils.GridHubConfiguration;
« org.openqa.selenium.server.SeleniumServer;

HUB Grid HUB Running as a standalone server: Hub is a central point which distributing tests on several node-machines, which are registered to it for parallel execution.

Use GRID HUB Server:

  • To distribute your tests over multiple machines or virtual machines (VMs).
  • You want to connect to a remote machine that has a particular browser version that is not on your current machine.

Start HUB Server

public class Grid_HUBServer {

    public static String HUBIP = GRIDINFO.HOSTIP.toString();
    public static Integer HUBPORT = 4444;
    static String separator = "\n------------------------\n";

    public static void hubServer() {
        try {
            GridHubConfiguration gridHubConfig = new GridHubConfiguration();
            gridHubConfig.setHost( HUBIP );
            gridHubConfig.setPort( HUBPORT );
            gridHubConfig.setNewSessionWaitTimeout( 50000 );
            File JOSNFile = new File(System.getProperty("user.dir")+"/gridHub.json" );
            gridHubConfig.loadFromJSON( JOSNFile.toString() );


            Hub hub = new Hub(gridHubConfig);
            hub.start();

            System.out.println("Nodes should register to " + hub.getRegistrationURL());
            System.out.format("%s Running as a grid hub: %s\n" +
                    "Console URL : %s/grid/console \n", separator,separator,hub.getUrl());

            System.out.println("Please Enter to stop service.");
            System.in.read();
            System.in.read();

            hub.stop();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        hubServer();
    }
}

NODE [RC] has to post a request to HUB in order to register with it, by this URL - IP:Port//grid/register.

public class Grid_NODEServer extends Grid_HUBServer {
    static Integer NODEPORT = 5555;
    static String PROXYCLASS = "org.openqa.grid.selenium.proxy.DefaultRemoteProxy";

    public static void nodeServer() {
        try {
            System.setProperty(ChromeDriverService.CHROME_DRIVER_EXE_PROPERTY, CHROME_DRIVER_EXE );
            System.setProperty(InternetExplorerDriverService.IE_DRIVER_EXE_PROPERTY, IE_DRIVER_EXE);


            RegistrationRequest request = new RegistrationRequest();
            request.setRole( GridRole.NODE );
            File JOSNFile = new File(System.getProperty("user.dir")+"/registerNode.json" );
            request.loadFromJSON( JOSNFile.toString() );

            Map<String, Object> configuration = new HashMap<String, Object>();

            URL remoteURL = new URL(String.format("http://%s:%d", HUBIP, HUBPORT) );
            System.out.println("Remote URL : "+remoteURL);
            configuration.put(RegistrationRequest.AUTO_REGISTER, true);
            configuration.put(RegistrationRequest.HUB_HOST, HUBIP);
            configuration.put(RegistrationRequest.HUB_PORT, HUBPORT);
            configuration.put(RegistrationRequest.REMOTE_HOST, remoteURL);

            configuration.put(RegistrationRequest.PORT, NODEPORT);

            configuration.put(RegistrationRequest.PROXY_CLASS, PROXYCLASS);
            configuration.put(RegistrationRequest.MAX_SESSION, 1);
            //configuration.put(RegistrationRequest.CLEAN_UP_CYCLE, 2000);
            //configuration.put(RegistrationRequest.MAX_INSTANCES, 1);

            request.setConfiguration( configuration );
            GridNodeServer node = new SeleniumServer( request.getConfiguration() );

            SelfRegisteringRemote remote = new SelfRegisteringRemote( request );
            remote.setRemoteServer( node );
            remote.startRemoteServer();
            System.out.format("Selenium Grid node is up and ready to register to the hub " +
                    "%s Running as a grid node: %s ", separator,separator);
            remote.startRegistrationProcess();

            System.out.println("Please Enter to stop service.");
            System.in.read();
            System.in.read();

            remote.stopRemoteServer();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        nodeServer();
    }
}
