repeated-test-composition

Sibling tests repeat service collaborator wiring or managed ASGI HTTP clients.

SARJ457 Rule source Tests Catalog JSON

Why

Repeated assembly hides scenario differences and spreads dependency signature changes across tests.

Fix

Move shared assembly into a function-scoped fixture or typed factory fixture; keep scenario values explicit.

Examples

Before — flagged Share managed test-client assembly
tests/test_client.py
from httpx import AsyncClient, ASGITransport




async def test_case_0(app):
    async with AsyncClient(
        transport=ASGITransport(app=app), base_url="http://test"
    ) as client:
        assert await client.get("/")




async def test_case_1(app):
    async with AsyncClient(
        transport=ASGITransport(app=app), base_url="http://test"
    ) as client:
        assert await client.get("/")




async def test_case_2(app):
    async with AsyncClient(
        transport=ASGITransport(app=app), base_url="http://test"
    ) as client:
        assert await client.get("/")
After — preferred Request a managed test client fixture
tests/test_client.py
async def test_response(client):
    assert await client.get("/")
