Test runner: --test-reporter-destination should create the folder if not found

[ClementValot]

What is the problem this feature will solve?

Hi 👋

Fairly easy one:
I have node --test --experimental-code-coverage --test-reporter-destination="coverage/lcov.info" outputting the coverage file to the coverage folder.

However, if the coverage folder does not exist beforehand, an ENOENT is thrown.

Since storing the behavior of storing coverage in coverage/lcov.info, and having that folder in .gitignore is rather standard, it'd be nice to have Node creating the folder in which it will place the coverage report in case it doesn't exist.

Thanks :)

What is the feature you are proposing to solve the problem?

When writing coverage report, check if the destination folder exists, and if not, create it beforehand

What alternatives have you considered?

• version controlling the coverage folder with a .gitkeep file, but it's cumbersome
• Having the CLI test script in my package json create the folder itself, but that's quite inelegant to maintain for both Windows and Unix users
• Switching to another test runner and losing all the charisma points that come with using the native one
