Running tests:
yarn test
Testing a specific browser:
yarn test --browsers FirefoxNightly
In test watch mode:
npx karma start --browsers FirefoxNightly
The version of karma-firefox-launcher used here should work under WSL but for
Chrome you'll want to use something like:
CHROME_BIN=/mnt/c/Program\ Files\ \(x86\)/Google/Chrome/Application/chrome.exe npx karma start --browsers Chrome
That will complain about not being able to write to the temp directory but otherwise should be fine.
