Firefox无法使用selenium网格

问题描述 投票：0回答：1

我想在多台机器中配置多个Firefox浏览器来执行并行测试。

提前致谢。

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

When I trigger Firefox (not parallel), it is working fine. JAVA Code below:

        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();

并行浏览的代码/设置我做了这个，它不工作

我在不同的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， seleniumProtocol =的webdriver”

JAVA Code for executing Firefox using remote driver

    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();

Error in Eclipse console:

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 [{}]

我看到几件可能导致你错误的事情。首先，版本3.1.0很旧，你应该使用3.14.0，geckodriver也已经使用版本0.21.0。对于最新的Realeses，请看这里：seleniumhq Secound，你应该使用FirefoxOptions作为RemoteDriver(UrlToHub,FirefoxOptions)的传输参数，并事先将你的DesiredCapabilities合并到FirefoxOptions中。正如我发现的最后一个问题，你使用http://localhost:4444/wd/hub作为网址。当您启动集线器时，您将看到要在控制台中注册的URL，该URL不在您的IP池中，您也应该使用它。要启动集线器，您只需要命令行命令：cd pathToSeleniumStandAloneServerFolder，启动命令为：java -jar selenium-standalone-<version>.jar -role hub端口“4444”是默认值

然后，您将看到连接RemoteWebDriver()的正确URL。它看起来像这样：

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

现在让我们开始使用NODE：

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;
    }

希望它有所帮助。
