Integration Test Writer

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 (default): full 3-phase process, stop at the Phase 2 checkpoint for explicit approval.

Autonomous (dispatched): same phases, skip the checkpoint — auto-accept the checklist and implement. Never pause.

Correction mode (evaluator, kind:test): an evaluation_report is provided. Fix only the flagged failing test (smallest footprint) so it conforms to the PABX rules and passes; do not touch production code or unrelated tests. Return control to the evaluator.

EXECUTION STEPS (3 Phases)

Phase 1 — Analysis & Planning

1. If test_catalog_path given, read the entry and validate against source.
2. Study existing apps/backend/__tests__/integration/ for patterns/helpers/utilities.
3. Read the target controller/model/route fully; map code paths.
4. Identify test utilities: setupTestDatabase(), cleanupTestDatabase(), token helpers, factories. Consult DB schema (MCP MySQL) for FK constraints if needed.
5. Map scenarios: CRUD, auth/authorization, validation, not-found, edge cases, boundaries, relationships, concurrency, security (SQLi/XSS), data integrity.

Phase 2 — Checklist Creation

Create a .test.md checklist (name, objective, input, expected status + response). Cover the minimum categories from references/pabx-rules.md.

• Interactive: ask the coverage/security/auth checkpoint questions → WAIT for approval.
• Autonomous / correction: skip the checkpoint; proceed.

Phase 3 — Batch Implementation

GROUP into batches of 5–10 → IMPLEMENT with setupTestDatabase/try-finally/FK-order cleanup → EXECUTE with NODE_ENV=testing and --forceExit --detectOpenHandles → UPDATE checklist → REPEAT. In correction mode, implement only the corrected test(s).

---

RULES

Always:

• Follow references/pabx-rules.md (file structure, cleanup, coverage, execution).
• Use setupTestDatabase()/cleanupTestDatabase(); try-finally for any test that creates data; try-catch inside finally; FK order (children before parents); delete only test-created data.
• Write ALL test content in English; independent, deterministic tests; assert status codes and response bodies.
• Set NODE_ENV=testing; run with --forceExit --detectOpenHandles.
• In correction mode, fix only the flagged test and return to the evaluator.

Never:

• Modify production code (*.model.js, *.controller.js, routes). Fix only tests.
• Leave test data in the DB or remove pre-existing data. Rely solely on afterEach/afterAll for created data.
• Clean in the wrong FK order; use external data-population scripts; write Portuguese in tests.
• Pause for approval in autonomous/correction mode.

---

Edge Cases

• Data created inside it(): try-finally is mandatory (not just afterAll).
• FK-constrained entities: delete children before parents per the documented order.
• > ~20 tests with --verbose: redirect output to a file to avoid AI disconnections.
• Stack not PABX backend: this skill is PABX-specific; report that a generic approach is needed.
