test_stress_elicitation_bypass.py
python
| 1 | """Stress and E2E tests for elicitation bypass paths. |
| 2 | |
| 3 | Covers: |
| 4 | Stress: |
| 5 | - 500 sequential compose_with_preferences bypass calls (throughput) |
| 6 | - 500 sequential review_pr_interactive bypass calls |
| 7 | - Large preferences dict (50 keys) does not crash the executor |
| 8 | - Concurrent bypass calls do not race on shared executor state |
| 9 | |
| 10 | E2E: |
| 11 | - Full tool dispatch chain: dispatcher → executor → result |
| 12 | - Schema guide returned when no session AND no bypass params |
| 13 | - Bypass overrides session path even when a session mock is present |
| 14 | - All 5 tools return ok=True on bypass path |
| 15 | - All 5 tools return ok=True schema_guide on no-session + no-params path |
| 16 | |
| 17 | Integration (async): |
| 18 | - create_with_preferences: empty preferences dict → plan with defaults |
| 19 | - review_pr_interactive: partial params (dimension only) → uses default depth |
| 20 | - connect_streaming_platform: known platform → OAuth URL in response |
| 21 | - connect_daw_cloud: known service → OAuth URL with capabilities |
| 22 | - create_release_interactive: full params → release created (DB write) |
