[🚀 Request] tests results as JSON file output

[brianignacio5]

Describe the request

Add additional output file.

I would like to generate a json file with the test results as is done in mocha.

I've tried using a .mocharc.js

module.exports = {
    reporter: 'json',
    'reporter-option': {
        output: './out/ui-test-results.json'
    }
} 

And while the console prints the expected mocha json output, I can't seem to generate the file.

Usage

I would like to use the json for a GitHub action dorny/test-reporter@v2 to show UI results.
