CLOUDP-286341: Validate Spectral Rule Application (PoC)

[yelizhenden-mdb]

Proposed changes

This PR implements a PoC for a custom Spectral formatter

You can test it out running node run-spectral.js
It will output JUnit formatted file with failures and successes.
Success means that the rule has no failure associated with itself.

Custom JUnit Formatter:

• Failures and the components associated
• Returns success for the rules that don’t have any failures associated with

Spectral running on JS file:

• Load ruleset
• Read OpenAPI spec file
• Run Spectral on OAS
• Write the results to a file

Deciding the successful ones:

• Collect all the components for a rule target (JSONPath lib)
• Check which components are marked as a failure
• Others left will be the successful ones for the rule

Catching the exemptions:

• Exempted components will not appear as failures
• We should collect them separately
• They are printed out, we can collect them with a Collector class

Note: This is not functioning as expected, but it serves as a foundational starting point for implementation
