# Tester — Phase 2-4

## Phase 2: Framework Detection & Test Discovery

**Framework detection** (priority order):

| Priority | Method | Frameworks |
|----------|--------|-----------|
| 1 | package.json devDependencies | vitest, jest, mocha, pytest |
| 2 | package.json scripts.test | vitest, jest, mocha, pytest |
| 3 | Config files | vitest.config.*, jest.config.*, pytest.ini |

**Affected test discovery** from executor's modified files:
- Search variants: `<name>.test.ts`, `<name>.spec.ts`, `tests/<name>.test.ts`, `__tests__/<name>.test.ts`

## Phase 3: Test Execution & Fix Cycle

**Config**: MAX_ITERATIONS=10, PASS_RATE_TARGET=95%, AFFECTED_TESTS_FIRST=true

1. Run affected tests → parse results
2. Pass rate met → run full suite
3. Failures → select strategy → fix → re-run → repeat

**Strategy selection**:

| Condition | Strategy | Behavior |
|-----------|----------|----------|
| Iteration <= 3 or pass >= 80% | Conservative | Fix one critical failure at a time |
| Critical failures < 5 | Surgical | Fix specific pattern everywhere |
| Pass < 50% or iteration > 7 | Aggressive | Fix all failures in batch |

**Test commands**:

| Framework | Affected | Full Suite |
|-----------|---------|------------|
| vitest | `vitest run <files>` | `vitest run` |
| jest | `jest <files> --no-coverage` | `jest --no-coverage` |
| pytest | `pytest <files> -v` | `pytest -v` |

## Phase 4: Result Analysis

**Failure classification**:

| Severity | Patterns |
|----------|----------|
| Critical | SyntaxError, cannot find module, undefined |
| High | Assertion failures, toBe/toEqual |
| Medium | Timeout, async errors |
| Low | Warnings, deprecations |

**Report routing**:

| Condition | Type |
|-----------|------|
| Pass rate >= target | test_result (success) |
| Pass rate < target after max iterations | fix_required |

## Error Handling

| Scenario | Resolution |
|----------|------------|
| Framework not detected | Prompt user |
| No tests found | Report to coordinator |
| Infinite fix loop | Abort after MAX_ITERATIONS |
