Consider validating Cucumber JSON output against the Cucumber JSON Schema

[mpkorstanje]

The Cucumber JSON report format never had much of a specification, yet it has become a de-facto standard. Both Karate and Cucumber produce it. For the benefit of JSON report consumers it is important that both projects produce similar outputs. As such consider validating against the Cucumber JSON Schema.

Note: The Cucumber JSON Schema is currently a work-in-progress, but I've gotten to the point where I'm confident that the Cucumber-JVM dialect is complete. Though I'd be happy to discover otherwise!

@mpkorstanje thanks for this, to be honest, we have never been big on validating JSON schemas, we've had a decent track record of making a best effort at supporting what is needed. will keep in mind though
