[quality] Missing unit tests for 4 build pipeline Python scripts

[hanthor-hive-agent]

Finding

The github-copr repository has 9 Python scripts in scripts/ but only 5 have corresponding tests in tests/. The following scripts have zero test coverage:

1. scripts/cleanup.py — CI workspace cleanup logic
2. scripts/copr-build-chain.py — COPR build dependency chaining
3. scripts/generate-distributed-workflow.py — Distributed CI workflow generation
4. scripts/parse-build-order.py — Build order YAML parsing

Additionally, the existing tests (tests/test_*.py) are minimal — 5 of them are only 14 lines each (just a basic import and null test).

Recommendation

Add meaningful unit tests for the untested scripts:

1. cleanup.py — test cleanup logic with temp directories
2. copr-build-chain.py — test dependency chain resolution with mock COPR API
3. generate-distributed-workflow.py — test workflow YAML generation with fixture inputs
4. parse-build-order.py — test YAML parsing with fixture build-order files

Expand existing tests to cover actual function behavior rather than just imports.

Priority

• Impact: medium — these scripts are build pipeline utilities, not user-facing
• Effort: medium — each script has clear input/output boundaries
