Specify browser location for wct-local test

Question

The Polymer Starter Kit contains web-component-tester for unit testing your custom elements.

In wct.conf.json you can specify the browsers to run the tests in.

{
  "suites": ["app/test"],
  "plugins": {
    "local": {
    "browsers": ["firefox"]
  }
}

Unfortunately, when I launch the tests through gulp, wct is not able to find my local Firefox. I read at GitHub that wct uses launchpad to detect local browsers. Afaik, on a Windows machine, launchpad searches for Firefox in the default directory "C:\Program Files\Mozilla Firefox". But I installed Firefox in a different directory.

Is there any way to configure the path to my Firefox dir in wct.conf.json?

Don't know how it works in the config but you can set an environment variable:

LAUNCHPAD_CHROME=/c/Users/you/chromium-v85/chrome.exe npm test
