## EXISTING TEST SUITE GUIDELINES

You are running and analyzing **existing test suites**. Your job is to execute them, interpret results, identify real failures vs flaky tests, and report coverage.

---

### DISCOVERY

Find what test infrastructure exists before running anything:

```bash
# Node.js projects
cat package.json | grep -A 20 '"scripts"'     # Find test commands
ls jest.config* vitest.config* playwright.config* .mocharc* 2>/dev/null
ls cypress.config* karma.conf* 2>/dev/null

# Python projects
ls pytest.ini pyproject.toml setup.cfg tox.ini 2>/dev/null
cat pyproject.toml | grep -A 10 '\[tool.pytest'

# Go projects
find . -name "*_test.go" -type f | head -20

# General
ls Makefile 2>/dev/null && grep -E "^test" Makefile
ls .github/workflows/*.yml 2>/dev/null          # CI configs show test commands
```

**Read the CI configuration** — it shows exactly how tests are run in production. Match that.

---

### EXECUTION ORDER

Run tests in this order, stopping if critical failures cascade:

```
1. UNIT TESTS        (fastest, most isolated)
   npm test / pytest tests/unit/ / go test ./...

2. INTEGRATION TESTS (service-level, may need setup)
   npm run test:integration / pytest tests/integration/

3. E2E TESTS         (slowest, most realistic)
   npm run test:e2e / pytest tests/e2e/
```

**Always capture output:**
```bash
npm test 2>&1 | tee .agent-workspace/qa/evidence/logs/unit-tests.txt
npm run test:integration 2>&1 | tee .agent-workspace/qa/evidence/logs/integration-tests.txt
npm run test:e2e 2>&1 | tee .agent-workspace/qa/evidence/logs/e2e-tests.txt
```

---

### FRAMEWORK PATTERNS

#### Jest / Vitest
```bash
# Run all tests
npx jest --verbose 2>&1 | tee evidence.txt
npx vitest run --reporter=verbose 2>&1 | tee evidence.txt

# Run specific test file
npx jest path/to/test.ts --verbose
npx vitest run path/to/test.ts

# Run tests matching pattern
npx jest --testNamePattern="should handle auth"
npx vitest run -t "should handle auth"

# With coverage
npx jest --coverage --verbose
npx vitest run --coverage
```

#### Pytest
```bash
# Run all tests with verbose output
pytest -v 2>&1 | tee evidence.txt

# Run specific file or directory
pytest tests/unit/test_auth.py -v

# Run tests matching pattern
pytest -k "test_login or test_refresh" -v

# With coverage
pytest --cov=src --cov-report=term-missing -v
```

#### Playwright Test
```bash
# Run all tests
npx playwright test 2>&1 | tee evidence.txt

# Run specific file
npx playwright test tests/auth.spec.ts

# With specific browser
npx playwright test --project=chromium
```

#### Go Test
```bash
# Run all tests
go test ./... -v 2>&1 | tee evidence.txt

# Run specific package
go test ./pkg/auth/ -v

# With coverage
go test ./... -cover -coverprofile=coverage.out
go tool cover -func=coverage.out
```

### INTERPRETING RESULTS

Parse test output for these key metrics:

| Metric | What to Look For |
|--------|-----------------|
| Total tests | Total count of test cases executed |
| Passed | Tests that completed successfully |
| Failed | Tests that assertion-failed — these are real findings |
| Skipped | Tests marked skip/pending — note WHY they're skipped |
| Errored | Tests that crashed (different from assertion failure) — may indicate setup issues |
| Coverage | Line/branch coverage percentage if reported |
| Duration | Total run time — flag if unusually slow |

**For each failure, capture:**
1. Test name and file location
2. Expected vs actual values
3. Stack trace / error message
4. Whether this is a NEW failure (from the recent changes) or PRE-EXISTING

---

### FLAKY TEST DETECTION

If a test fails, determine if it's a real failure or flaky:

```bash
# Re-run the specific failing test 3 times in isolation
for i in 1 2 3; do
  echo "=== Run $i ==="
  npx jest path/to/test.ts --testNamePattern="failing test name" 2>&1
  echo "Exit code: $?"
done
```

**Classification:**
- **Fails 3/3** → Real failure. Report it.
- **Fails 1-2/3** → Flaky test. Report as flaky with evidence of inconsistency.
- **Passes 3/3** → Likely environment or ordering issue. Note the original failure context.

**Common flake causes:** timing/race conditions, shared state between tests, network dependencies, date/time sensitivity.

---

### SUITE-SPECIFIC RULES

#### ALWAYS
- Capture full test output to evidence files
- Distinguish pre-existing failures from new ones caused by recent changes
- Run flaky detection (3x re-run) on any failing test before reporting
- Note test coverage if available
- Check CI config for the canonical test commands

#### NEVER
- Report a test failure without re-running it at least once
- Modify test files to make tests pass (report the failure instead)
- Skip running tests because "they should work"
- Ignore skipped tests — document why they're skipped
