java - 在 Docker 中运行 Selenium 测试时出现连接被拒绝的 UnreachableBrowserException

Question

我正在尝试在 Docker 中运行以下简单的 Selenium 测试(使用 Docker 工具箱安装在 Window10 Home 中)。 我收到了 UnreachableBrowserException。 下面是我尝试在 Docker 容器中运行的测试。

    URL url=new URL("http://localhost:4444/wd/hub");
    DesiredCapabilities dc=DesiredCapabilities.chrome();
    RemoteWebDriver rDr=new RemoteWebDriver(url,dc);
    rDr.get("https://www.google.com");
    System.out.println(rDr.getTitle());
    rDr.quit();

下面是我收到的错误。

INFO: Using `new ChromeOptions()` is preferred to `DesiredCapabilities.chrome()`
Exception in thread "main" org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
