Add test cases for the validation script

[TommiLindfors]

What needs doing

Our scripts/validate.py validates YAML data against JSON Schemas, but we need test cases to make sure it catches errors correctly.

Steps

1. Look at tests/ to see the existing test structure
2. Create test YAML files with intentional errors (missing required fields, wrong types, invalid IDs)
3. Add test cases that verify validate.py rejects these invalid files
4. Add test cases that verify valid files pass
5. Run tests to make sure they pass

Time estimate

~30 minutes

Skills needed

Basic Python and YAML knowledge.

Hi, I’d like to work on this issue. I’ll review the existing test structure and add test cases for scripts/validate.py covering both valid and intentionally invalid YAML files.

Hi @Presmanes3! 👋 Welcome to Clarvia, and thanks for volunteering!

This is a great issue to pick up. The validation script is at scripts/validate.py and currently runs against the JSON schemas in schemas/v0.1/. A few pointers to get you started:

• Valid test cases: You can use the existing YAML files in data/sources/lu/ as valid examples
• Invalid test cases: Create intentionally broken YAML files (missing required fields, wrong types, extra properties, bad ID patterns, etc.) and assert that the validator catches them
• Test framework: We don't have a preference — pytest would be a natural fit

Feel free to open a draft PR when you have something started and we'll help you iterate. Looking forward to your contribution! 🙏
