使用 Selenium 在 Headless Chrome 中全屏显示 [英] Fullscreen in Headless Chrome using Selenium

问题描述

我在 E2E 套件中进行了许多测试，其中视频元素全屏显示并验证全屏状态.但是，在无头运行套件时，这些测试会失败.该页面的屏幕截图显示视频根本没有全屏显示，即使在单击全屏按钮后也是如此.有没有办法在无头 Chrome 中实现全屏功能?

这是我的配置中的功能示例.

功能:[{'浏览器名称':'铬'，'goog:chromeOptions': {args: ['无头']}}]

解决方案

当添加参数 --start-fullscreen 来初始化

结论

因此可以得出结论，在--headless模式下，Chrome浏览器总是以800 x 600px 大小忽略自定义的 --window-size 参数.

I have a number of tests in an E2E suite where a video element is fullscreened and the fullscreen status is verified. However, when running the suite headlessly, these tests fail. Screenshots of the page show the video is simply not in fullscreen, even after the fullscreen button is clicked. Is there a way to achieve fullscreen functionality in headless Chrome?

Here is an example of the capabilities in my config.

capabilities: [
    {
        'browserName': 'chrome',
        'goog:chromeOptions': {
            args: ['headless']
        }
    }
]

解决方案

When the argument --start-fullscreen is added to initialize google-chrome in normal mode it seems the screen size is:

1366 x 724px

Snapshot:

Whilst google-chrome-headless when initiated additionally with either of the arguments:

• --start-maximized
• --kiosk
• --start-fullscreen

The resultant screen size is always:

800 x 600px

Snapshot:

Conclusion

So it can be concluded that in --headless mode Chrome browser always opens in 800 x 600px size ignoring the customized --window-size arguments.
