java可以指定webdriver。壁虎。节点中的驱动程序。使用selenium网格的json？

Question

我有一本书。Eclipse中的4.0脚本以及-

beforeClass() throws MalformedURLException {
        System.out.println("geckodriver: "+geckoPath);    // set to  "C:\Selenium\selenium-java-3.4.0\geckodriver-v0.18.0-win32\geckodriver.exe"
        //    FOR FF 53.0.2
        System.setProperty("webdriver.gecko.driver", geckoPath);
        baseUrl = "http://www.expedia.co.uk";
        nodeURL = "http://192.168.124.128:5555/wd/hub";    //    WindowsVM
        DesiredCapabilities caps = DesiredCapabilities.firefox();
        caps.setBrowserName("firefox");
        caps.setPlatform(Platform.WINDOWS);
        driver = new RemoteWebDriver(new URL(nodeURL), caps);

        searchPage = new SearchPageFactory(driver);

        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        driver.get(baseUrl);
    }

当我用DOS命令启动节点时，这个脚本在我的Windows10VM上运行得非常好-

java -jar -Dwebdriver.gecko.driver=C:\Selenium\selenium-java-3.4.0\geckodriver-v0.18.0-win32\geckodriver.exe selenium-server-standalone-3.4.0.jar -role node -hub http://ASUSLaptop:4444/grid/register -port 5555 -browser browserName=firefox,version=53.0.2,maxInstances=2,platform=WINDOWS

如果我用-

java -jar selenium-server-standalone-3.4.0.jar -nodeConfig GridNode.json

Gridnode所在的位置。json是-

{
"capabilities":
[
    {
    "browserName": "firefox",
    "maxInstances": 1,
    "seleniumProtocol": "WebDriver",
    "webdriver.gecko.driver": "C:\\Selenium\\selenium-java-3.4.0\\geckodriver-v0.18.0-win32\\geckodriver.exe"
    },
    {
    "browserName": "chrome",
    "maxInstances": 1,
    "seleniumProtocol": "WebDriver",
    "webdriver.chrome.driver": "C:\\Selenium\\selenium-java-3.4.0\\chromedriver_win32\\chromedriver.exe"
    },
    {
    "browserName": "internet explorer",
    "maxInstances": 1,
    "seleniumProtocol": "WebDriver"
    }
],
"proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
"maxSession": 2,
"port": 5555,
"register": true,
"registerCycle": 5000,
"hub": "http://ASUSLaptop:4444",
"nodeStatusCheckTimeout": 5000,
"nodePolling": 5000,
"role": "node",
"unregisterIfStillDownAfter": 60000,
"downPollingLimit": 2,
"debug": false,
"servlets" : [],
"withoutServlets": [],
"custom": {}
}

。。然后相同的脚本失败，并出现错误-

geckodriver: C:\Selenium\selenium-java-3.4.0\geckodriver-v0.18.0-win32\geckodriver.exe

Answer 1

您可以在将浏览器作为

if (browser.equalsIgnoreCase(Consts.FIREFOX)) {
  System.setProperty("webdriver.firefox.marionette", getRootDir() + "/src/main/java/configuration/geckodriver");
  driver = new FirefoxDriver();
} 

Answer 2

似乎您需要在命令行本身中传递geckodriver路径。我尝试在功能和配置json中传递路径，但没有成功。您可以在此处阅读有关此问题的信息： https://github.com/SeleniumHQ/selenium/issues/3051
