Notes for the Reviewer

• Adds a new JSON reporter, very similar in implementation and usage to the github reporter.
• Renders the output to a file named checkly-json-report.json.
• File can be renamed by setting the variable CHECKLY_REPORTER_JSON_OUTPUT
• Works with npx checkly test and npx checkly trigger by using --reporter json

How do I test this?

Run any test or trigger command with the --reporter json flag. Optionally add the --record flag. Inspect the output in the saved JSON file.

Output looks like:
