# Phase 5: Verification and QA (QA)

## Objective
Comprehensively verify that all cleanup goals have been achieved and the integration test suite is professional, evergreen, and fully functional.

## Context
This is the final quality assurance phase. We'll run a complete checklist to ensure:
1. All file naming issues resolved
2. All duplicate files removed
3. All content markers removed
4. All tests still pass
5. Test coverage maintained or improved

## Files to Review
- All files in `tests/integration/`
- Cleanup inventory and summary

## Implementation Steps

### Step 1: File Naming Verification

#### 1.1: Check for process hints in file names

```bash
echo "=== Checking for process hints in file names ==="

# Should find ZERO files
echo "Files with '_fix':"
find tests/integration -name "*_fix.py" | wc -l

echo "Files with '_regression':"
find tests/integration -name "*_regression.py" | wc -l

echo "Files with '_simple':"
find tests/integration -name "*_simple.py" | wc -l

echo "Files with '_extended':"
find tests/integration -name "*_extended.py" | wc -l

echo "Files with '_complex':"
find tests/integration -name "*_complex.py" | wc -l

echo "Files with '_fixed':"
find tests/integration -name "*_fixed.py" | wc -l

echo "Files with '_native':"
find tests/integration -name "*_native*.py" | wc -l

echo "Files with '_fixes':"
find tests/integration -name "*_fixes.py" | wc -l

echo "Files with 'phase' in name:"
find tests/integration -name "*phase*.py" | wc -l

echo ""
echo "ALL COUNTS ABOVE SHOULD BE 0"
```

**Expected output**: All counts = 0

**If any count > 0**:
- List the files: `find tests/integration -name "*_fix.py"` (replace pattern)
- Return to Phase 3 and rename those files

#### 1.2: List all test files (sanity check)

```bash
# Show all test files - manually review for any odd names
find tests/integration -name "test_*.py" | sort | head -20
```

**Action**: Scan the list for any remaining unprofessional names.

### Step 2: Duplicate Files Verification

#### 2.1: Check specific duplicate groups from Phase 2

```bash
echo "=== Checking duplicate files were removed ==="

echo "Field authorization duplicates:"
ls tests/integration/auth/test_field_authorization*.py 2>/dev/null | wc -l
echo "  Expected: 1 (only test_field_authorization.py)"

echo "Error array duplicates:"
ls tests/integration/graphql/mutations/test_*error*.py 2>/dev/null | wc -l
echo "  Expected: 1 (only test_error_arrays.py)"

echo "Decorator files:"
ls tests/integration/auth/test_decorator*.py 2>/dev/null | wc -l
echo "  Expected: 1 (only test_decorators.py)"

echo "Validator files:"
ls tests/integration/auth/test_validator*.py 2>/dev/null | wc -l
echo "  Expected: 1 (only test_validators.py)"
```

**Expected output**: Each count = 1

**If counts are wrong**: Files weren't properly merged/deleted in Phase 2

#### 2.2: Check for unexpected duplicates

```bash
# Find potential duplicates (same base name)
find tests/integration -name "test_*.py" | sed 's/_[^_]*\.py$/.py/' | sort | uniq -d
```

**Expected output**: Empty (no duplicate base names)

### Step 3: Content Markers Verification

#### 3.1: Check for work package references

```bash
echo "=== Checking for WP- references ==="
grep -r "WP-[0-9]" tests/integration --include="*.py"

# Count
count=$(grep -r "WP-[0-9]" tests/integration --include="*.py" | wc -l)
echo "Found: $count (expected: 0)"
```

**Expected output**: Found: 0

#### 3.2: Check for Phase references

```bash
echo "=== Checking for Phase references ==="
grep -r "Phase [0-9]" tests/integration --include="*.py"

count=$(grep -r "Phase [0-9]" tests/integration --include="*.py" | wc -l)
echo "Found: $count (expected: 0)"
```

**Expected output**: Found: 0

#### 3.3: Check for TDD markers

```bash
echo "=== Checking for TDD markers ==="
grep -r "\[RED\]\|\[GREEN\]\|\[REFACTOR\]\|\[QA\]" tests/integration --include="*.py"

count=$(grep -r "\[RED\]\|\[GREEN\]\|\[REFACTOR\]\|\[QA\]" tests/integration --include="*.py" | wc -l)
echo "Found: $count (expected: 0)"
```

**Expected output**: Found: 0

#### 3.4: Check for regression language

```bash
echo "=== Checking for regression/fix language ==="
grep -ri "regression test\|verifies the fix\|this fixes\|before the fix\|after the fix" tests/integration --include="*.py"

count=$(grep -ri "regression test\|verifies the fix\|this fixes\|before the fix\|after the fix" tests/integration --include="*.py" | wc -l)
echo "Found: $count (expected: 0)"
```

**Expected output**: Found: 0

#### 3.5: Check for version numbers

```bash
echo "=== Checking for version numbers ==="
grep -r "v[0-9]\+\.[0-9]\+\.[0-9]\+" tests/integration --include="*.py"

count=$(grep -r "v[0-9]\+\.[0-9]\+\.[0-9]\+" tests/integration --include="*.py" | wc -l)
echo "Found: $count (expected: 0)"
```

**Expected output**: Found: 0

#### 3.6: Check class names

```bash
echo "=== Checking for process hints in class names ==="
grep -r "class Test.*Fix\|class Test.*Regression\|class TestPhase" tests/integration --include="*.py"

count=$(grep -r "class Test.*Fix\|class Test.*Regression\|class TestPhase" tests/integration --include="*.py" | wc -l)
echo "Found: $count (expected: 0)"
```

**Expected output**: Found: 0

#### 3.7: Check function names

```bash
echo "=== Checking for process hints in function names ==="
grep -r "def test_.*_fix\|def test_.*_regression" tests/integration --include="*.py"

count=$(grep -r "def test_.*_fix\|def test_.*_regression" tests/integration --include="*.py" | wc -l)
echo "Found: $count (expected: 0)"
```

**Expected output**: Found: 0

### Step 4: Test Suite Functionality

#### 4.1: Run full integration test suite

```bash
echo "=== Running full integration test suite ==="
uv run pytest tests/integration/ -v --tb=short
```

**Expected output**: All tests pass

**Critical**: If ANY tests fail, stop and investigate:
1. Which test failed?
2. Is it related to cleanup changes?
3. Fix before proceeding

#### 4.2: Run with coverage report

```bash
echo "=== Running with coverage ==="
uv run pytest tests/integration/ --cov=fraiseql --cov-report=term-missing --cov-report=html
```

**Expected output**:
- Coverage percentage (note this number)
- HTML report generated in `htmlcov/`

**Action**: Compare coverage to pre-cleanup baseline. Should be same or better.

#### 4.3: Check for skipped or xfailed tests

```bash
echo "=== Checking for skipped/xfailed tests ==="
uv run pytest tests/integration/ -v | grep -E "SKIPPED|XFAIL|XPASS"
```

**Expected output**: List of any skipped/xfailed tests

**Action**: Review list - are these expected? Or did cleanup break something?

Integration test suite is now evergreen and production-ready."
```

## DO NOT

- ❌ Skip any verification checks
- ❌ Accept any non-zero counts in marker checks
- ❌ Proceed if tests are failing
- ❌ Ignore warnings or unexpected output

## Troubleshooting

**Problem**: Verification finds remaining markers
**Solution**:
1. Run the specific check to see which files: `grep -r "WP-" tests/integration --include="*.py"`
2. Return to Phase 4, clean those files
3. Re-run verification

**Problem**: Tests are failing
**Solution**:
1. Identify which test: `uv run pytest tests/integration/ -v | grep FAILED`
2. Run that test individually: `uv run pytest path/to/test.py::TestClass::test_function -v`
3. Check if failure is related to cleanup
4. Fix and re-run full suite

**Problem**: Coverage dropped
**Solution**:
1. Generate HTML coverage report: `uv run pytest tests/integration/ --cov=fraiseql --cov-report=html`
2. Open `htmlcov/index.html` in browser
3. Identify uncovered lines
4. Check if consolidation accidentally removed tests
5. Restore missing tests

**Problem**: Git shows unexpected changes
**Solution**:
1. Review: `git diff`
2. Check if changes are related to cleanup
3. If unrelated, stash them: `git stash`
4. Re-run verification

## Notes for Junior Engineers

**What does "evergreen" mean?**
Code that doesn't reveal when it was written. It looks like it was always this way, professional and timeless.

**Why so many checks?**
Quality assurance requires thoroughness. Better to catch issues now than in production or code review.

**What if I find issues during QA?**
Don't skip ahead. Fix the issue in the appropriate phase, re-commit that phase, then continue QA.

**How do I know if coverage dropped for a good reason?**
It shouldn't drop. If it does, you likely removed a test during consolidation. Review Phase 2 work.

**What's the final deliverable?**
A clean integration test suite with:
- Professional file names
- Clear, focused documentation
- No historical artifacts
- 100% tests passing
- Maintained coverage

**Time estimate**: ~30 minutes
- Verification checks: ~15 minutes
- Test runs: ~10 minutes
- Documentation: ~5 minutes

**After this phase**:
The cleanup is complete! The integration test suite is production-ready and maintainable.
