Empty code coverage (vscode development)

[rwalle]

I was trying to understand VSCode code structure and testing philosophy, and tried to get code coverage on Linux according to the instructions:

https://github.com/microsoft/vscode/blob/main/test/unit/README.md#os-x-and-linux

I got here by following the links in Wiki:

Writing Tests -> Unit Tests (in the sentence "Tests can be run manually on the command line, see the instructions here.")

However I got empty coverage result. It seems that test.sh does not have any logic around handling the --coverage flag.

My guess is that the instructions are outdated, and manual coverage collection requires a different process?

Does this issue occur when all extensions are disabled?: N/A
