I'm on Alpine Linux running JS tests. With CHROME_BIN=chromium-browser however it complains that Running as root without --no-sandbox is not supported. . I'm trying to add the --no-sandbox option, however I can't add it to CHROME_BIN . Is there an option somewhere in the multiplatform plugin to handle this? And if not, what are the solutions?

I haven't figured it out just yet but you can put config files in the project directory under the karma.config.d directory (create it yourself) or whichever test framework you're using like mocha.config.d etc.

the frontend plugin talks about it here for webpack for instance

Hi, you can check this thread

Tl;dr you need to use option useConfigDirectory . And then you need to create folder <http://karma.com|karma.com>fig.d where you can create plain js files, in which you can configure karma config via config variable, and add your own browser launchers (including no-sandbox option). But do you really need to run with super user? If you will run with limited user there isn’t this kind of error

kotlin {
 js {
  browser {
   testTask {
    useKarma {
     useConfigDirectory()
    }
   }
  }
 }
}

super user is a convenience inside docker images

I actually just got it working by realizing I can set flags that get picked up by ubuntu images.
echo "CHROMIUM_FLAGS=\"--no-sandbox --headless --disable-gpu\"" > ~/.chromium-browser.init

your example (patricks, rather) is kind of a bummer as it seems I had been really close to figuring it out reading the plugin source but I couldn't find a way to make it work in a kts file so a little comedy there.

Thanks a lot for your replies, I'll try it out ^^
