运行 selenium 远程驱动程序时出现带有 NativeConstructorAccessorImpl.newInstance0 的错误 SessionNotCreatedException

2022-01-15 00:00:00 selenium selenium-chromedriver selenium-webdriver selenium-grid java

我正在运行以下但收到错误

I am running the following but getting the error

public class base
{
    public static WebDriver driver;

    public static void main(String[]  args) throws MalformedURLException, InterruptedException
    {
        System.setProperty("webdriver.chrome.driver", "C:\code\lib\browser drivers\chromedriver.exe");

        String URL = "http://www.google.com";
        String Node = "http://localhost:4444/wd/hub";
        DesiredCapabilities cap = DesiredCapabilities.chrome();
        cap = DesiredCapabilities.chrome();
        cap.setPlatform(org.openqa.selenium.Platform.WINDOWS);


        driver = new RemoteWebDriver(new URL(Node), cap);

        driver.navigate().to(URL);
        Thread.sleep(5000);
        driver.quit();
    }       
}

错误显示如下:

Exception in thread "main" org.openqa.selenium.SessionNotCreatedException: Unable to create new service: ChromeDriverService

有人可以帮忙吗

推荐答案

请执行以下操作并重试.

Please do the following and retry.

确保将路径 C:\code\lib\browser drivers\chromedriver.exe 添加到计算机上的 %PATH% 变量中您正在运行的节点.这将确保 selenium uber jar 可以找到 chromedriver 二进制文件的位置.

Ensure that the path C:\code\lib\browser drivers\chromedriver.exe is added to your %PATH% variable on the machine in which you are running the node. This would ensure that the selenium uber jar can find the location of the chromedriver binary.

System.setProperty("webdriver.chrome.driver", "C:codelibrowser driverschromedriver.exe");

这个机制应该只在你做的时候使用

This mechanism should be only used when you are doing

ChromeDriver 驱动程序 = ChromeDriver()

由于您使用的是 selenium 网格，因此您在这里处理的是多个 JVM.

Since you are working with a selenium grid, you are dealing with multiple JVMs here.

System.setProperty() 只会影响当前的 JVM(在这种情况下是您的测试)，但实际的浏览器会在不同的 JVM(运行 selenium 的那个节点).

System.setProperty() will affect only the current JVM (which in this case is your tests), but the actual browser gets spun off in a different JVM (the one that is running the selenium node).
