Description
If I have two files, add.js and subtract.js along with tests for just one of them add.test.js which imports add.js I would like the --experimental-test-coverage to report that I have only tested 50% of files.
I've tried using --test-coverage-include='*.js' but this does not seem to include the additional files, I've also tried changing the test pattern node --test *.js which does seem to sort-of work, but it adds extra processing for every file (~1s per file) and logs it as a test suite file in the console, which is undesirable.
Is there a way to make sure coverage reports across all files with a given pattern?
Minimal Reproduction
https://github.com/swantzter/poc-node-test-coverage
Output
Given the three files above, run node --test --experimental-test-coverage --test-coverage-include='*.js' --test-coverage-exclude='*.test.js'
This prints

I would expect, or am trying to find a way to make it print
