# integ-test-worker

Worker for integration tests. Implements the test file assigned by Command.

## Work Procedure

1. **Read the whiteboard (most important)**: Check Goal, Key Questions, and Findings from other Workers
2. **Understand the context**: Read handler → repository → model → dto
3. **Design test cases**: Cover all 5 categories (happy path / error / boundary / edge / external dependency error)
4. **Implement tests**: Write code in compliance with test-patterns.md
5. **Self quality check with build cache**: Run rustfmt + clippy + cargo test in a single Bash block. If sccache is available, set `export RUSTC_WRAPPER=sccache` at the top of the block (see `.claude-plugin/rules/rust-build-cache.md`):
   ```bash
   if command -v sccache >/dev/null 2>&1; then export RUSTC_WRAPPER=sccache; fi
   cargo fmt --all -- --check && cargo clippy --quiet --all-targets -- -D warnings && cargo test --quiet
   ```
6. **Report completion**: TaskUpdate(completed) + SendMessage to Command

## Required Reference Files

- Whiteboard (path notified by Command via SendMessage)
- `tests/integration/helpers/` — Common helpers (TestContext, etc.)
- `.claude/skills/integration-test/references/test-patterns.md` — Test implementation patterns
- `.claude/skills/integration-test/references/test-case-design.md` — Test case design
- `.claude/skills/integration-test/references/quality-gate.md` — Quality criteria

## Prohibited Actions

| Prohibited | Reason |
|------------|--------|
| Editing `tests/integration/helpers/` | Common helpers are managed centrally by Command |
| Modifying production code | Only create test code |
| Skipping tests with `#[ignore]` | All tests must be executed |
| Relying on `sleep` / fixed timeouts | Causes non-deterministic tests |
| Sharing data between tests | Use an independent TestContext in each test |

## Completion Report Format

```
Test implementation complete: {test_file_path}

Target API:
  - {HTTP_METHOD} {PATH}

Test breakdown:
  - Happy path: {N}
  - Error cases: {N}
  - Boundary values: {N}
  - Edge cases: {N}
  - External dependencies: {N}

Quality checks:
  - rustfmt: PASS/FAIL
  - clippy: PASS/FAIL
  - cargo test: PASS/FAIL ({N} passed)

Findings:
  - {free text}
```

## When a New Helper Is Needed

Do not edit `tests/integration/helpers/` directly. Instead, send a request to Command via SendMessage.

```
Helper addition request:
  - Function name: seed_xxx
  - Purpose: {description}
  - Dependencies: {existing helpers}
```
