How do I specify the path to chrome.exe when configuring capybara for a rails project running in a W-CodePudding

I'm developing my Rails application in a WSL environment on Windows 11.

I use VS Code for my editor, and use the WSL - Remote extension to connect to the WSL filesystem, edit my app, etc.

When I run rake test:system I get:

blaine@blaine_ems_dev:~/myapp$ rake test:system
rake aborted!
Webdrivers::BrowserNotFound: Failed to find Chrome binary.
/home/blaine/myapp/test/application_system_test_case.rb:7:in `<class:ApplicationSystemTestCase>'
/home/blaine/myapp/test/application_system_test_case.rb:3:in `<main>'
/home/blaine/myapp/test/system/customer_administration_stories_test.rb:1:in `<main>'
Tasks: TOP => test:system
(See full trace by running task with --trace)

Neat thing is, I can open Chrome via WSL by issuing this command:

/mnt/c/Program\ Files/Google/Chrome/Application/chrome.exe

Is there some way I can simply plug in the path to the Windows binary I have installed, and have it run my system tests?

Or perhaps there's a better way altogether?

CodePudding user response：

You can override webdrivers attempt to detect the location of Chrome by setting Selenium::WebDriver::Chrome.path to the location of your Chrome binary or you can set the WD_CHROME_PATH environment variable.

CodePudding user response：

Under WSL, you are running the Linux version of Ruby, which won't be able to communicate via WebDriver with the Windows Chrome executable.

Similar to this Python/Selenium/WSL2 question, you'll need to install the Linux Chrome executable.

Since you have Windows 11, that shouldn't be a problem since it supports running GUI apps through WSLg. I've successfully run Selenium using xrdp with Python on Windows 10, and I just ran ruby2d for another Ask Ubuntu question on Windows 11 using WSLg, so I'm fairly confident this will work for you.
