we need a way to test for `nim js -d:nimbrowser`

@xflywind @juancarlospaco now that nim-lang/fusion#64 was merged, let's discuss how to fix this; lots of nim js code (eg @juancarlospaco's wrappers) can only be tested inside a browser environment. There's 2 things to do IMO (and we should do both):

• easier: nim js -r --port:1234 main: open in browser a template html that calls generated js, use livereload server etc; ditto with nim doc -r #165 (won't run in CI but at least can be run locally to test nim js browser code)
• harder (this issue): run in CI, either selenium or webdriver or chromium etc. At least running on 1 browser (eg chromium) would be a good start

My idea was to make a pure-nim stdlib-only single-file KISS way of testing those things,
thats why I sent nim-lang#15828 the solution was literally there,
with that integrated and tested with Nim you can create a browser specifically designed for testing on <500 LOC

It is financed by Petrobras big oil corp, coded by Lua creators, 100% C, moves slow like ~1 version/year.

Now we need a GUI module on stdlib for "Finish.exe GUI", but we removed all of them.

🤷

With bindings for puppeteer this would be doable.
