What product do you want to improve?
I wonder if it's possible to use codecov with the node's new test runner: https://nodejs.org/api/test.html#collecting-code-coverage

I've tried following:

nyc --reporter=lcov node --test --experimental-test-coverage

— but nyc doesn't seem to pick anything.

Running just node --test --experimental-test-coverage works locally, though.

Here is the full yml script I'm trying to make work: https://github.com/Elringus/DotNetJS/blob/feat/revamp/.github/workflows/cover.yml (tests are here: https://github.com/Elringus/DotNetJS/tree/feat/revamp/JavaScript).

This may be due to configuration with nyc and not with Codecov at all.
