Tests Manager

Overview

Use this skill as the entry point for Python pytest work. It defines the shared testing rules, then routes to focused references or agents only when the project needs them.

Coverage Routing

For a behavior change, decide the minimum useful coverage before writing tests:

Change	Unit tests	Integration tests
Pure function, schema, validation, branch, or error handling	Required	Usually not needed
Service or repository behavior behind an interface	Required	Add when real dependency or query wiring matters
New or changed endpoint or feature	Required for local branches and edge cases	Required for real route, dependency, or resource wiring
Bug fix	Required reproduction test	Add only if the bug was caused by integration wiring

For a new endpoint or feature in general, normally write both unit and integration coverage.

Reference Loading

Use the frontmatter metadata as the routing table. Load only the reference or agent whose metadata value matches the current task, and skip the rest.

Shared Pytest Rules

• Use test_*.py; do not use .spec.* or *_test.py.
• Mirror source paths under tests/unit/ and tests/integration/; create directories only when adding tests in that area.
• Group tests with class TestThing: or class TestMethodName: when it helps scan related behavior.
• Name functions test_condition_expected_result; use descriptive snake_case and avoid vague names like test_works.
• Keep each test focused on one behavior. Split tests whose name needs "and".
• Use @pytest.mark.parametrize when three or more cases differ only by input and expected output.
• Put shared fixtures in the narrowest useful conftest.py.
• Put static payloads under tests/fixtures/.
• Use deterministic helpers for reusable test entities.

Delegation

Use metadata-listed agents when the caller needs substantial test generation, read-only review, or focused pytest execution.

When both unit and integration tests are needed, use the same source change as input for both writer agents and keep their scopes separate.

Pre-Finish Checklist

• Every changed behavior has at least one focused test.
• Bug fixes include a regression test that would fail on the old behavior.
• Unit tests cover branches, guard clauses, exceptions, and edge values.
• Integration tests cover wiring-sensitive paths without repeating every unit case.
• Fixtures and reusable builders are reused instead of duplicated inline data.
• Task-specific references were loaded only when metadata matched the task.
• Focused pytest command has been run, or the reason it could not run is reported.
