Firefox不能使用selenium网格

Question

我想用配置在多台机器中的多个Firefox浏览器执行并行测试。

提前道谢。

Firefox版本:60.0.1
Selenium Firefox驱动程序:3.7.1
Geckdriver版本:v0.19.0

        System.setProperty("webdriver.gecko.driver","C:\\Fm2\\Try_Browsers\\Browsers\\drivers\\geckodriver_19.exe");
        WebDriver driver = new FirefoxDriver();
        driver.get("https://www.google.com/");
        driver.close();     

我在不同bat文件中设置了网格和节点:
HUb设置:
java-jar selenium-server-standalone-3.1.0.jar-port 4444-role HUb
节点设置:
java-dwebdriver.gecko.driver=./geckodriver_19.exe-jar selenium-server-standalone-3.1.0.jar-port 5557-role node-hub http：//localhost:4444/grid/register-browser“browsername=firefox,maxinstances=10,platform=any

    System.setProperty("webdriver.gecko.driver","C:\\Fm2\\Try_Browsers\\Browsers\\drivers\\geckodriver.exe");
    DesiredCapabilities cap = DesiredCapabilities.firefox();
    cap.setBrowserName("firefox"); 
    cap.setPlatform(Platform.ANY);              
    WebDriver driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), cap);   
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    driver.get("https://www.google.com/");
    driver.close(); 

Exception in thread "main" org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session. desired capabilities = Capabilities [{acceptInsecureCerts=true, browserName=firefox, moz:firefoxOptions=org.openqa.selenium.firefox.FirefoxOptions@21fa0ed7, version=, platform=ANY, firefox_profile=org.openqa.selenium.firefox.FirefoxProfile@49991a02}], required capabilities = Capabilities [{}]

Answer 1

我看到有几件事会导致你的错误。首先，3.1.0版本已经很旧了，您应该使用3.14.0，而且geckodriver已经有了0.21.0版本。对于der最新的现实，请参见这里：seleniumhq Secound，您应该使用FirefoxOptions作为远程驱动程序(UrlToHub，FirefoxOptions)的传输参数，并预先将您所需的功能合并到FirefoxOptions中。我看到的最后一个问题是，您使用http://localhost:4444/wd/hub作为URL。当您启动集线器时，您将看到一个要在控制台中注册的URL，而该URL不在您的IP池中，您也应该使用该URL。要启动集线器，您只需要命令行命令:cd pathtoseleniumstandaloneserverfolder，start命令是:java-jar selenium-standalone- .jar-role hub 端口“4444”是默认的

然后您将看到连接RemoteWebDriver()的正确URL。它看起来是这样的：

c:usr\Downloads>java -jar "selenium-server-standalone-3.14.0.jar" -role hub
12:56:40.723 INFO [GridLauncherV3.launch] - Selenium build info: version: '3.14.0', revision: 'aacccce0'
12:56:40.725 INFO [GridLauncherV3$2.launch] - Launching Selenium Grid hub on port 4444
2018-09-07 12:56:41.063:INFO::main: Logging initialized @588ms to org.seleniumhq.jetty9.util.log.StdErrLog
12:56:41.447 INFO [Hub.start] - Selenium Grid hub is up and running
12:56:41.448 INFO [Hub.start] - Nodes should register to http://192.168.56.1:4444/grid/register/
12:56:41.448 INFO [Hub.start] - Clients should connect to http://192.168.56.1:4444/wd/hub

最后一行是RemoteWebDriver()的可连接URL

现在让我们以以下内容开始节点：

java -Dwebdirver.gecko.driver="PathToYourFirefoxDriver" -jar selenium-standalone-server-<versio>.jar -role node -hub http:UrlToHub:port/grid/register

看看这个例子：

    public WebDriver getWebDriver(final DesiredCapabilities desiredCapabilities) {
        FirefoxOptions firefoxOptions;

        DesiredCapabilities capabilities = new DesiredCapabilities()
        capabilities.merge(desiredCapabilities);
        capabilities.setPlatform(Platform.ANY);
        capabilities.setBrowserName("firefox");
        firefoxOptionHelper.merge(capabilities);

       try {
            WebDriver webDriver = new RemoteWebDriver(new URL(this.gridHubUrl), firefoxOptions);
            return webDriver;
        } catch (MalformedURLException e) {
            e.printStackTrace();
        }
        return null;
    }

希望能有所帮助。
