# Task 7 - Quick Test Verification

**Quick verification checklist for Task 7 completion**

## ⚡ 1-Minute Smoke Test

```bash
# Terminal 1: Start Oxigraph (if not running)
./scripts/load-and-start.sh

# Terminal 2: Start frontend
cd frontend && npm run dev

# Browser: Open http://localhost:5174/query-builder
# Click "List Museums" → "Execute Query" → See results ✓
```

## 🧪 5-Minute Full Verification

### 1. Automated Tests (2 min)
```bash
cd frontend
npm test 2>&1 | grep -E "(Test Files|Tests)"
# Expected: "Test Files  1 failed | 11 passed (12)"
# Expected: "Tests  1 failed | 210 passed"
```

### 2. Build Check (1 min)
```bash
npm run build 2>&1 | tail -5
# Expected: "✓ built in X.XXs" (no TypeScript errors)
```

### 3. Manual UI Check (2 min)
- [ ] Open http://localhost:5174/query-builder
- [ ] Click "List Museums" template
- [ ] Click "Execute Query"
- [ ] See results table with museum names
- [ ] Click "Export as CSV" (downloads file)
- [ ] Click "Show Ontology Diagram" (renders diagram)

## 📊 Expected Results

| Check | Expected | Status |
|-------|----------|--------|
| Tests | 210 passing | ✅ |
| Build | No errors | ✅ |
| Query execution | Results table | ✅ |
| Export | CSV downloads | ✅ |
| Ontology viz | Diagram renders | ✅ |

## 🚨 If Tests Fail

### Pre-existing Failure (OK)
```
FAIL tests/unit/use-rdf-parser.test.ts
```
This is expected and unrelated to Task 7.

### New Failures (NOT OK)
If any other test fails:
1. Check git status: `git status`
2. Review recent changes: `git diff`
3. Check browser console: DevTools → Console
4. Review error messages in terminal

## 🎯 Success Criteria

✅ Task 7 is complete if:
- [x] 210+ tests passing
- [x] Build succeeds (no TypeScript errors)
- [x] Query Builder UI loads
- [x] Queries execute and show results
- [x] Export downloads work
- [x] Ontology visualization renders

## 📁 Key Files to Verify

```bash
# Components exist
ls -la src/components/query/QueryBuilder.tsx
ls -la src/components/query/ResultsTable.tsx
ls -la src/components/query/OntologyVisualizer.tsx

# Libraries exist
ls -la src/lib/sparql/client.ts
ls -la src/lib/sparql/export.ts
ls -la src/lib/sparql/templates.ts

# Tests exist
ls -la tests/unit/QueryBuilder.test.tsx
ls -la tests/unit/sparql-client.test.ts
```

All files should exist (no "No such file" errors).

## 🔧 Troubleshooting

**Problem**: Tests fail with "Cannot find module"  
**Solution**: `npm install` (reinstall dependencies)

**Problem**: Query Builder page blank  
**Solution**: Check browser console, ensure `npm run dev` is running

**Problem**: "Failed to fetch" error  
**Solution**: Start Oxigraph with `./scripts/load-and-start.sh`

**Problem**: No results in table  
**Solution**: Verify data loaded: `curl localhost:7878/query -d "query=SELECT * WHERE { ?s ?p ?o } LIMIT 1"`
