Requirements
Description of the Change
Added an optional CLI argument ('jsw' or 'jsonStringifyWhitespace') that allows for the user to set the whitespace of the JSON reporter. If it isn't provided it defaults to the current value (2).
This change allows for more customization of the JSON output!
Closes #4889
Alternate Designs
An alternative approach might involve using a boolean CLI argument to toggle the JSON reporter and remove whitespace. However, a more precise level of customization can be achieved by using a CLI argument to control the amount of whitespace instead.
Why should this be in core?
It's a relatively simple change that simplifies the parsing of the JSON output."
Benefits
This feature would prove valuable when parsing JSON test results. For example, Splunk mandates JSON formatting with no whitespace, and having the option to generate whitespace-free JSON would enable Splunk to directly use the data without additional processing.
Possible Drawbacks
There shouldn't be any drawbacks to making this modification. It allows for further customization but is kept default if not specified.
