使用硒进行测试:Chrome屏幕共享自动选择标签并与音频共享 [英] testing using selenium: chrome screensharing auto select tab and share with audio

问题描述

我正在使用Selenium测试我的网站，并且能够使用-auto-select-desktop-capture-source ="tab_name" 打开chrome，并在启用屏幕共享时选择标签.现在，我希望选项卡中播放的音频与视频一起出现在我的视频流中.手动进行操作时，有一个复选框可以启用音频共享，但是是否有一些可以从Selenium中启用它的功能?

I am testing my website using Selenium and I am able to open chrome with --auto-select-desktop-capture-source="tab_name" and select the tab when screen share is enabled. Now I want the audio playing in the tab to be in my stream along with the video. While doing it manually there is a checkbox which enables audio sharing but is there something which can help enable it from Selenium?

这里是一个小提琴: https://jsfiddle.net/john_vera/yr2k9xob/5/在对话框中选择镶边选项卡后，请注意共享音频复选框​​.我想从硒中检查一下.

Here is a fiddle: https://jsfiddle.net/john_vera/yr2k9xob/5/ Notice the Share Audio checkbox after selecting chrome tab in the dialog. I want to check that from Selenium.

推荐答案

您可以创建自定义的Chrome构建并为此对话框实现绕过.要生成铬，您可以使用以下说明(适用于Windows):此处

You could create an custom chromium build and implement an bypass for this dialog. To build chromium you can use these instructions (for windows): Here

这是文件display_media_access_handler.cc中的旁路:

Here the bypass in file display_media_access_handler.cc:

寻找这一行:

// Orignal code
pending_request.picker->Show(picker_params, std::move(source_lists), std::move(done_callback));

并替换为此

// Bypass dialog
content::DesktopMediaID screenSource(content::DesktopMediaID::TYPE_SCREEN, content::DesktopMediaID::kNullId, web_contents);
screenSource.audio_share = true;

OnPickerDialogResults(web_contents, screenSource);
// End of bypass

我用Chromium 84版进行测试.

I testet it with Chromium Version 84.
