What steps will reproduce the bug?
Pointing to ts files
NODE_V8_COVERAGE=./coverage node -r ts-node/register --test --experimental-test-coverage src/**/*.spec.ts
No coverage is reported
How often does it reproduce? Is there a required condition?
Always
Pointing to js files creates a coverage folder
NODE_V8_COVERAGE=./coverage node -r ts-node/register --test --experimental-test-coverage src/**/*.spec.js
What is the expected behavior? Why is that the expected behavior?
To have coverage
What do you see instead?
Seems coverage reporter is filtering out files that don't have extension
- js
- cjs
- mjs

Why would you expect that to work? Node doesn't handle .ts files. You're probably thinking of ts-node but that's a different project.

Because --test works.
If node:test works using ts-node as loader why would the coverage reporting not work?
MoLow commentedon Aug 30, 2023
No reason for it not to work. The only issue is the code isn't mapped correctly to the source since there is no source maps but that shouldn't prevent reporting statistics.
