Question

我正在尝试让我的Selenium Grid在Chrome驱动程序上运行。

起初我开始使用集线器和节点： java -jar selenium-server-standalone-2.45.0.jar -role hub java -jar selenium-server-standalone-2.45.0.jar -role node -hub http://localhost:4444/grid/register

比我启动我的测试：

public class ChromeDriverTest {
    private WebDriver driver = null;
    String  BaseURL,NodeURL;

@Before
public void before() throws Exception{
    BaseURL="http://www.google.com";
    NodeURL="http://localhost:4444/wd/hub";
    File file = new File("C:\\Users\\pushkaryova\\Desktop\\Nexus\\driver\\chromedriver.exe");
    System.setProperty("webdriver.chrome.driver", file.getAbsolutePath());
    DesiredCapabilities capa =DesiredCapabilities.chrome();
    capa.setBrowserName("chrome");
    capa.setPlatform(Platform.ANY);
    driver=new RemoteWebDriver(new URL(NodeURL),capa);
}

@Test
public void GoogleSearch() throws Exception {
    driver.get("http://www.google.com");
    WebElement searchBox = driver.findElement(By.xpath("//div[3]/div/input[1]"));
    hightlight(searchBox);
    driver.findElement(By.xpath("//div[3]/div/input[1]")).clear();
    driver.findElement(By.xpath("//div[3]/div/input[1]")).sendKeys("Test");
    driver.findElement(By.xpath("//button")).click();

}

public void hightlight(WebElement webElement) throws InterruptedException {
    for (int i = 0; i < 2; i++) {
        JavascriptExecutor js = (JavascriptExecutor) driver;
        js.executeScript(
                "arguments[0].setAttribute('style', arguments[1]);",
                webElement, "color: red; border: 3px solid red;");
    }
}

}

并收到错误消息： org.openqa.selenium.WebDriverException：驱动程序可执行文件的路径必须由webdriver.chrome.driver系统属性设置

我的代码有什么问题？

Answer 1

driver可执行文件需要在节点计算机上物理可用。您可以在启动node

时设置exe的路径

在命令

中添加此行

-Dwebdriver.chrome.driver=./chromedriver.exe

我从json文件配置它，发现它更容易

json文件，名称为DefaultNode.json

{
  "capabilities":
      [
        {
          "browserName": "firefox",
          "maxInstances": 5,
          "seleniumProtocol": "WebDriver"
        },
        {
          "browserName": "chrome",
          "maxInstances": 5,
          "seleniumProtocol": "WebDriver"
        },
        {
          "platform": "WINDOWS",
          "browserName": "internet explorer",
          "maxInstances": 1,
          "seleniumProtocol": "WebDriver"
        }
      ],
  "configuration":
  {
    "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
    "maxSession": 5,
    "port": 5555,
    "host": ip,
    "register": true,
    "registerCycle": 5000,
    "hubPort": 4444,
    "hubHost": ip
  }
}

使用json config启动节点

java -jar selenium-server-standalone-2.45.0.jar -role webdriver -nodeConfig DefaultNode.json -Dwebdriver.ie.driver=.\IEDriverServer.exe

请注意 IEDriverServer.exe 与json文件放在同一目录中

Answer 2

这适用于3.3.1及以上的

java -Dwebdriver.chrome.driver="C:\chromedriver.exe" -jar selenium-server-standalone-2.45.0.jar -role node -hub localhost:4444/grid/register -browser "browserName=chrome,version=ANY,platform=WINDOWS,maxInstances=20" -maxSession 20

Webdriver路径应放在-jar选项

之前

Answer 3

您可以将节点作为：

启动

java -jar selenium-server-standalone-2.45.0.jar -role node -hub localhost:4444/grid/register -browser "browserName=chrome,version=ANY,platform=WINDOWS,maxInstances=20" -Dwebdriver.chrome.driver="C:\chromedriver.exe" -maxSession 20

Answer 4

您可以在系统变量（对于Windows）中设置包含chromedriver可执行文件的文件夹的路径。

为我摆脱了错误。

Answer 5

当我像下面这样在json配置文件中添加两个属性时，我可以使用硒网格远程运行chrome和firefox：注意最后两行

{
  "capabilities":
  [
    {
      "browserName": "firefox",
      "marionette": true,
      "maxInstances": 5,
      "seleniumProtocol": "WebDriver"
    },
    {
      "browserName": "chrome",
      "maxInstances": 5,
      "seleniumProtocol": "WebDriver"
    },
    {
      "browserName": "internet explorer",
      "platform": "WINDOWS",
      "maxInstances": 1,
      "seleniumProtocol": "WebDriver"
    },
    {
      "browserName": "safari",
      "technologyPreview": false,
      "platform": "MAC",
      "maxInstances": 1,
      "seleniumProtocol": "WebDriver"
    }
  ],
  "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
  "maxSession": 5,
  "port": -1,
  "register": true,
  "registerCycle": 5000,
  "hub": "http://192.168.1.2:4444",
  "nodeStatusCheckTimeout": 5000,
  "nodePolling": 5000,
  "role": "node",
  "unregisterIfStillDownAfter": 60000,
  "downPollingLimit": 2,
  "debug": false,
  "servlets" : [],
  "withoutServlets": [],
  "custom": {},
  "webdriver.gecko.driver":"c:/drivers/geckodriver.exe",
  "webdriver.chrome.driver":"c:/drivers/chromedriver.exe"
}

带有Chrome驱动程序的Selenium网格（WebDriverException：驱动程序可执行文件的路径必须由webdriver.chrome.driver系统属性设置）
