java - Java 中的 Selenium Grid : org. openqa.selenium.SessionNotCreatedException:无效参数:无法终止已退出的进程

Question

我想用 Java 编写一个 Selenium Grid 应用程序。

关于http://localhost:4444/grid/console它表示该节点已连接到集线器。

在客户端我想编写以下内容:

try {
        DesiredCapabilities capability = DesiredCapabilities.firefox();

        WebDriver driver = new RemoteWebDriver(new URL("http://IP of Hub:4444/wd/hub"), capability);
        capability.setBrowserName("firefox");
        driver.get("https://www.google.com");

} catch (MalformedURLException ex) {
        System.err.println("URL Exception: "+ex.getMessage());
}

不幸的是，运行客户端应用程序时抛出以下异常:

    Exception in thread "main" org.openqa.selenium.SessionNotCreatedException: invalid argument: can't kill an exited process
...
Driver info: driver.version: unknown

Answer 1

在初始化 webdriver 实例之前提供 geckodriver 路径，

try {
     DesiredCapabilities capability = DesiredCapabilities.firefox();
     System.setProperty("webdriver.gecko.driver", "/PATH_OF_DRIVER/geckodriver.exe");
     driver = new RemoteWebDriver(new URL("http://Hub_IP/wd/hub"), capability);
     capability.setBrowserName("firefox");
     driver.get("https://www.google.com");

} catch (MalformedURLException ex) {
     System.err.println("URL Exception: "+ex.getMessage());
}
