Hi,
Currently, the coverage-collector dumps the coverage data in "TeamScale Simple Coverage" format. It would be helpful if the coverage data can be dumped in different formats like JSON, lcov etc.

Thanks.

Following the documentation, we ran the instrumenter but passed a url starting with http:// as --collector option:

npx @teamscale/javascript-instrumenter \
    test/casestudies/angular-hero-app/dist/ \
    --collector http://foo.bar:1234 \
    --in-place \
    --include-origin src/app/**/*

This results in NaN being set as url in the instrumented scripts.

IMHO we should either simply remove http(s):// prefixes (preferred) or throw an error in case an unexpected url is passed.

I have tried to run the instrumentation step both with npx and after building locally.
Both times the source-map library complained.
Adding the following code to App.ts has fixed the issue for me

		//@ts-ignore
		SourceMapConsumer.initialize({
			"lib/mappings.wasm": "https://unpkg.com/[email protected]/lib/mappings.wasm",
		  })

I am happy to provide more details for this problem

Hello!

I am trying to use the tool on an app (web app) to collect coverage during automated UI test runs.

Well, so far:

• I've run instrumenter successfully
• I can run my app
• I started collector
• Once app launches I can see logs:

Starting coverage forwarding worker.
Received coverage mapping information for "dd26609bf0e13e1e77ee3dd93d50ea17774a92b5".
Connection to Coverage Collector established.

• If I go to network tab, find the websocket connection and go to messages - I can see one message sent. source map details, seems like.

So here I am. As I click through the app, I do not see any other websocket messages sent.
Collector does not log anything upon the initial message receipt. (I can see a path inside, should I run collector from a specific place? I actually tried it.) still, would be nice to have a lot line saying that initial connection ok, code is available, everything is visible etc.
I assume because web app does not send any new ws messages, I get 0 lines coverage dumps on the way.

Happy to provide more info, just not sure what else is relevant.

Thank you!
