Selenium网格节点有许多phantomjs并发实例

我正在努力添加一个包含许多并发PhantomJS实例的节点。在GhostDriver github页面上,您可以找到只注册一个PhantomJS实例的指令:

phantomjs --webdriver=8080 --webdriver-selenium-grid-hub=http://127.0.0.1:4444

我不允许发布图片,所以这里是使用以下方法添加节点后的网格视图: enter image description here

此处的配置标签内容:

port:6666
servlets:[]
host:null
cleanUpCycle:5000
browserTimeout:0
hubHost:127.0.0.1
registerCycle:5000
hub:http://127.0.0.1:4444/grid/register/
capabilityMatcher:org.openqa.grid.internal.utils.DefaultCapabilityMatcher
newSessionWaitTimeout:-1
url:http://127.0.0.1:6666
remoteHost:http://127.0.0.1:6666
prioritizer:null
register:true
throwOnCapabilityNotPresent:true
nodePolling:5000
proxy:org.openqa.grid.selenium.proxy.DefaultRemoteProxy
maxSession:1
role:wd
jettyMaxThreads:-1
hubPort:4444
timeout:300000

由于selenium grid允许从命令行定义节点浏览器,我尝试使用phantomjs,但正如你所看到的那样here它不受支持。

  

允许参数-browser:browserName = {android,chrome,firefox,htmlunit,internet explorer,iphone,opera} version = {browser version} firefox_binary = {path to executable binary} chrome_binary = {path to executable binary} maxInstances = {此类型的最大浏览器数}} platform = {WINDOWS,LINUX,MAC}

努力解决同样的问题: 我期望实现以下架构(下面的屏幕): archtecture

但是我面临以下问题: 1)如果我们使用以下参数配置selenium-server-(在UI方式上配置,即通过ffox,chrome或IE配置) 喜欢

java -jar  selenium-server-standalone-2.41.0.jar -role node -hub htt
p://localhost:4444/grid/register -port 7575 -browser  browserName=firefox,maxIns
tances=5,platform=WINDOWS

然后我们获得所需的结果:http://gyazo.com/6cd19155c78a59b22a09f4a3da3439b5 我想请注意,使其成为可能的主要参数是: -browser browserName = firefox,maxInstances = 5,platform = WINDOWS

但是,例如GhostDriver超过phantomJs,我们预计不会启动selenium-server-.jar而是phantomjs.exe app,它不支持-browser参数: unknown parameter unknown parameter 2

根据list of allowed phantomjs parameters,与5个并发的firefox实例相比,我设法只启动了1 phantom jsInstance

可能对您有所帮助 - 现在我正在重新设计我的测试架构并尝试调整以下内容: 1 NODE = 1个PhantomJs实例。 reorganized test architecture

在localhost上,可以使用不同的端口运行许多节点(IE,Ffox,Chrome): http://gyazo.com/302fab9b6722251aa2cc6d98e2522931


这个解决方案对我有用:

  • 关于项目结构的一些话: 我有linux机器(192.34.61.205,selenium hub在这里运行)和~20个与之相关的幻像节点: http://gyazo.com/0a3a50f2ee1638d10b1766e300438891 在所有节点上,phantomJs作为服务运行(为了在节点上重新启动phantomJs,只需输入命令sudo service phantomjs restart

某些节点具有以下IP: 162.243.175.134 162.243.175.97 162.243.175.252 ....

public class BrowserOneInstance extends BaseMethodsForMultipleBrowsers {

    private WebDriver driver;

    private final static Logger log = LoggerFactory.getLogger(BrowserOneInstance.class);
    public static LoginPage loginPage;
    public static FacebookUserPage homePage;

    FileOperations fileManipulator = new FileOperations();


//staring   hub - nodes model (on local WIN machine) over GhostDriver- pHantomJS

    @BeforeClass
    public void seleniumGrridUponGhostDriver() throws MalformedURLException {


//        File phantomjs = Phanbedder.unpack(); //Phanbedder to the rescue!

        File phantomjs = new File(System.getProperty("java.io.tmpdir")+File.separator+"phantomjs-1.9.7");


        DesiredCapabilities dcaps = new DesiredCapabilities();
        dcaps.setCapability("takesScreenshot", true);


        dcaps.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY, phantomjs.getAbsolutePath());

// !!!!! hardCoded initizliations of GhostDriver node
//        driver = new RemoteWebDriver(new URL("http://localhost:8080"), dcaps);

//    driver initialization   using  method  providing IP of running Ghost node connected to running hub
//        this.driver= new RemoteWebDriver(new URL("http://"+getGhostNodesIp()+":8080"),dcaps);

//        node  connected to linux hub:
        this.driver = new RemoteWebDriver(new URL("http://162.243.175.134:8080"), dcaps);


        driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
        driver.manage().timeouts().pageLoadTimeout(30, TimeUnit.SECONDS);

        //page instances init()
        loginPage = PageFactory.initElements(driver, LoginPage.class);
        homePage = PageFactory.initElements(driver, FacebookUserPage.class);
    }

      @Test
 public void abracadabraTestMethod(){

  ....
 }


        @AfterTest
    public void driverTearDown() {
//        close any of the instances: either Firefox or GhostDriver
        driver.quit();
    }

}

注意:

如果您希望使phantomJs以跨平台方式工作,从而消除手动替换 你可以使用Phanbedder - PhantomJS Windows/Mac OS X/Linux native binary embedder

import net.anthavio.phanbedder.Phanbedder;

......

 @BeforeClass
    public void seleniumGrridUponGhostDriver() throws MalformedURLException {

        File phantomjs = Phanbedder.unpack(); //Phanbedder to the rescue!


        DesiredCapabilities dcaps = new DesiredCapabilities();
        dcaps.setCapability("takesScreenshot", true);


        dcaps.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY, phantomjs.getAbsolutePath());


        this.driver = new RemoteWebDriver(new URL("http://162.243.175.134:8080"), dcaps);

......

希望这适合你。

我使用自己的Docker容器工作了: https://github.com/madhavajay/selenium-node-phantomjs

它使用PhantomJS 2.1.1自定义构建,然后我自己修改Ghostdriver以允许--remoteHost,以便Grid可以连接回Docker容器,无论它在哪个主机上。

我希望这有助于其他人。 :)
