Is there any way to run Dawn without Chrome?

[MVEMCJSUNPE]

Summary

It seems that Dawn needs Chrome to work. However, even with chrome, it doesn't seem to work.

Steps To Reproduce The Bug

I have chrome installed (on Windows), and I try to run the example ts file in the README, app_test.ts:

deno test --allow-run app_test.ts

I get failures for both, even though one should pass (ignore my horribly misconfigured prompt):

According to the first test, it should pass, but it doesn't. If we look at the stack trace, we find three relevant files: app_test.ts, dawn.ts, and headless_browser.ts. Since headless_browser.ts is the relevant file closest to the top of the stack, it is most likely that the error is there. If we take a look at headless_browser.ts:
https://github.com/drashland/dawn/blob/833b6a1d118868289d03129bb9e3cf898f75dd74/src/headless_browser.ts#L101-L108

So it appears that Deno is executing "start chrome", but for some reason, it can't find it? However, I have chrome, and 'start chrome' seems to work when I run it from the command prompt:

Expected Behavior

I expect dawn to run app_test.ts with the first test passing and the second test failing.

Suggested Solution(s)

My best hypothesis is that Deno doesn't inherit the PATH from Command Prompt. I still think it would be really cool to let Dawn run without requiring Chrome.

Hey @MVEMCJSUNPE, See #20, #19 and the warning in the README.md, Dawn/Cinco (we're renaming this repo to Sinco actually) is still a WIP and doesn't actually work - the code i've added in the v1 PR does work, it's just there's an issue with WebSockets that's preventing the tests from working

Though firefox would be another option, good shout 👍

This is ssomething. we should implement, but it seems there's just a lack of documentation on how to connect to a headless firefox instance

But specific to this issue, i have been reading up on it, and so far i've found:

How to create a headless browser instance

$ /Applications/Firefox.app/Contents/MacOS/firefox --headless --start-debugger-server 9293

For windows, there's only one dash

How to connect to the process

Still unsure. Severe lack of documentation

How to send commands and run actions

No information.

There's literally no information anywhere, and most posts are just like this: https://stackoverflow.com/questions/47874959/firefox-remote-debugging-using-websocket, a perfect question with no answer
