Write Python Tests

Guidelines

• files to update: tests/
• Ensure tests are comprehensive and coverage is good.
• Existing docs, docstrings, tests, examples may be rough, missing, incomplete or misleading, it only serves as weak hint.
• Favor bold, comprehensive rewrites over minor or incremental edits.
• Group tests into files and folders, keep test files small and focused.
• Source code is the source of truth.
• Use nox to run full test suites.
• Use pytest for targeted test runs and debugging.

Validation

• Run mise run lint.
• Start with the narrowest relevant target.
• Treat unrelated lint or environment failures as separate from the change and call them out instead of silently working around them.
