在Selenoid中运行Selenide测试时出现enableVNC W3C Capabilities错误求助

错误信息 #

Caused by: java.lang.IllegalArgumentException: Illegal key values seen in w3c capabilities: [enableVNC]

Docker Compose配置 #

version: '3.8'

services:
  selenoid:
    image: aerokube/selenoid:latest-release
    container_name: selenoid
    network_mode: bridge
    ports:
      - "4444:4444"
    volumes:

      - "/var/run/docker.sock:/var/run/docker.sock"
    command: ["-limit=4", "-capture-driver-logs", "-max-timeout=0h5m0s"]

原浏览器配置代码 #

import static com.codeborne.selenide.Configuration.*;

browser = CHROME;
browserVersion = "113.0";
browserSize = "1920x1080";
capabilities.setCapability("enableVNC", true);
browserCapabilities = capabilities;

配置文件：

selenide.remote=http://localhost:4444/wd/hub

问题原因 #

enableVNC是Selenoid专属的扩展配置项，不属于W3C标准的浏览器能力范畴，直接放在顶层capabilities中会触发W3C能力校验失败，从而抛出错误。这类Selenoid特定配置需要统一放在selenoid:options命名空间下。

修正后的代码 #

ChromeOptions options = new ChromeOptions();
options.setCapability("browserVersion", "113.0");
options.setCapability("selenoid:options", new HashMap<String, Object>() {{
    /* 添加测试标识 */
    put("name", scenario.getName());
    /* 开启视频录制 */
    put("enableVideo", true);
    /* 开启VNC */
    put("enableVNC", true);
    /* 设置视频文件名 */
    put("videoName", scenario.getName());
}});
browserCapabilities = options;
