# Integration Test Writer (PABX) Plan and implement high-quality **integration tests** that validate real API behavior against a real test database (full request→response lifecycle: middleware, controller, model, DB). **Never modifies production code** — if a test fails, only the test is adjusted. > **Project scope:** PABX backend. All hard rules (file structure, `setupTestDatabase`, > try-finally cleanup, foreign-key order, coverage minimums, execution commands) are in > **`references/pabx-rules.md`** — read it before writing. > Generic SDD flow docs: `https://github.com/dayvisonassis/sdd-skills/blob/main/docs/GUIA_DO_WORKFLOW.md`. **Scope:** `apps/backend/__tests__/integration/`. ## INPUT - `target_file_or_endpoint` (required) — controller, route, or endpoint (e.g. `POST /v2/calltype`). - `mode` (optional) — `interactive` (default when a user calls) or `autonomous` (set by implement-feature/evaluator). - `test_file_path` / `focus_areas` / `batch_size` (optional). - `test_catalog_path` (optional) — Test Catalog entry to accelerate Phase 1. - `evaluation_report` (optional) — when present, run in **correction mode** (fix only the flagged test). ## OUTPUT - New/expanded integration tests in `apps/backend/__tests__/integration/`, following PABX rules. - A `.test.md` checklist (planning may be Portuguese; **all test code is English**). - Per-batch execution confirmation and a final coverage summary. Production code untouched. --- ## Invocation Modes **Interactive (defau
