Is it possible to use an alternative Chromium?

[danilokleber]

Summary

I use https://github.com/ungoogled-software/ungoogled-chromium and despite setting WD_CHROME_PATH="/Applications/Chromium.app/Contents/MacOS/Chromium" webdrivers can't locate the Chrome binary.

Debug Info

• Webdrivers version: 5.0.0
• Ruby version: 2.7.6
• Operating system / CI Environment: macOS 12.5
• Browser and version: Chromium version 104.0.5112.81 (Official Build, ungoogled-chromium) (arm64)

Expected Behavior

webdrivers to locate the Chrome binary.

Actual Behavior

Both Selenium and webdrivers will check here for a user-set value:

Selenium::WebDriver::Chrome.path = "/path/to/alternative/chromium"
