我是Selenium的新手。我正在尝试使用远程web驱动程序启动Chrome。下面是我正在使用的环境。
Windows : Windows 10 Enterprise
Java Version : 9.0.4
Selenium Standalone Jar : 3.5.3
IDE : Eclipse
在我的本地机器上启动集线器和节点服务器，如下所示在一个CMD会话-
java -jar selenium-server-standalone-3.5.3.jar -role hub

在另一个CMD会话中，我像下面这样-

我有Chrome的代码如下-
public class ChromeFactory extends DriverFactory{
String mcWebUrl;
public ChromeFactory(String mcURL) {
mcWebUrl = mcURL;
initBrowser();
}
@Override
protected void initBrowser() {
try {
DesiredCapabilities cap = new DesiredCapabilities();
cap.setBrowserName("chrome");
URL remoteUrl = new URL("http://*******:4444/wd/hub");
WebDriver driver = new RemoteWebDriver(cap);
driver.get(mcWebUrl);
} catch (MalformedURLException e) {
e.printStackTrace();
}
我得到下面红色的消息，这就是所有的浏览器不启动-
May 25, 2022 10:23:25 PM org.openqa.selenium.remote.tracing.opentelemetry.OpenTelemetryTracer createTracer
INFO: Using OpenTelemetry for tracing
WebDriver driver = new RemoteWebDriver(cap);
您缺少参数URL
正确的调用方法是:
URL remoteUrl = new URL("http://*******:4444/wd/hub");
WebDriver driver = new RemoteWebDriver(*remoteUrl* , cap);
