jq_validations.md

Absolutely. To simplify the JQ validation for testing purposes — while still exercising the validation engine and ValidationResult logic — we can write a basic expression that:

1. Produces an error if a required field (e.g., bmaController) is missing or blank.
2. Produces a warning if a certain condition is met (e.g., vendor is "DELL").

Here’s a minimal JQ validation snippet that can be easily tested and reliably produces validation output:

✅ Simplified JQ Validation Expression

{
  "debug": $input,
  "errors": {
    "bmaController": [
      (if ($input.bmaController | tostring | length) == 0 then "bmaController is required" else null end)
    ]
  },
  "warnings": {
    "vendor": [
      (if ($input.vendor | ascii_downcase) == "dell" then "Dell machines may need firmware updates" else null end)
    ]
  }
} | with_entries(select(.value | type == "object") | .value |= with_entries(select(.value != null)))

---

💡 Explanation

• "debug": $input: Echoes back the input for debugging.

• Errors

  • Triggers if bmaController is missing or empty.

• Warnings

  • Triggers if vendor is "dell" (case-insensitive).

• with_entries(...): Removes null entries from both errors and warnings.

🧪 Sample Input for Testing

{
  "bmaController": "",
  "vendor": "dell",
  "serialNo": "1234"
}

✅ Expected Output

{
  "debug": {
    "bmaController": "",
    "vendor": "dell",
    "serialNo": "1234"
  },
  "errors": {
    "bmaController": ["bmaController is required"]
  },
  "warnings": {
    "vendor": ["Dell machines may need firmware updates"]
  }
}

validation:
  - type: JQ

          ]
        }
      }
      | with_entries(select(.value | type == "object") | .value |= with_entries(select(.value != null)))

Let me know if you’d like a version that incorporates lookup response logic or produces multiple errors/warnings.
