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)

2022-01-15 00:00:00 selenium selenium-chromedriver java selenium-grid2

我正在尝试让我的 Selenium Grid 在 Chrome 驱动程序上运行.

I am trying to get my Selenium Grid running on Chrome driver.

一开始我启动了集线器和节点:java -jar selenium-server-standalone-2.45.0.jar -role hubjava -jar selenium-server-standalone-2.45.0.jar -role node -hub http://localhost:4444/grid/register

At first I started hub and node: 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

然后我开始我的测试:

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;");
    }
}

}

并得到一个错误: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

and get an error: org.openqa.selenium.WebDriverException: The path to the driver executable must be set by the webdriver.chrome.driver system property

我的代码有什么问题?

推荐答案

driver 可执行文件需要在节点机器上物理可用.您可以在启动node

The driver executable needs to be avaiable physically on node machine. You can set the path to exe while starting the node

在命令中添加这一行

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

我从 json 文件中配置了这个，发现这更容易

I configure this from json file and found that's little easier

名为 DefaultNode.json 的 json 文件

{
  "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 配置启动节点

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

注意 IEDriverServer.exe 与 json 文件放在同一目录

Notice the IEDriverServer.exe is placed in same directory with json file
