The GET /api/documents/ response is {items: [...], total: N, ...} not a
bare list. Change docs = resp.json() to resp.json().get("items", []) so
get_document task correctly accesses docs[0]["id"] without TypeError.

"""Locust load test for DocuVault — D-04, D-05, D-06.
|
|
|
|
Strategy: self-bootstrapping (Option A) — on_start registers the load-test
|
|
user (409 ignored if already exists), then logs in to get an access token.
|
|
|
|
Run (headless, matches Phase 6 SLA gate):
|
|
locust --headless --users 50 --spawn-rate 10 --run-time 5m \\
|
|
--host http://localhost:8000 \\
|
|
--csv backend/load_tests/results \\
|
|
-f backend/load_tests/locustfile.py
|
|
|
|
Prerequisites:
|
|
pip install -r backend/requirements-dev.txt
|
|
docker compose up # backend, postgres, minio must be running
|
|
|
|
Exit codes (enforced by check_sla listener):
|
|
0 — all SLA thresholds met
|
|
1 — p95 > 200 ms, OR p99 > 500 ms, OR fail_ratio > 1%
|
|
|
|
Cleanup the load-test user:
|
|
docker compose exec postgres psql -U docuvault -c \\
|
|
"DELETE FROM users WHERE email='loadtest@example.com';"
