## 3. Test Data & Fixtures

### 3.1 Package Fixtures

**Fixture Categories:**
1. **Minimal Packages (10)** - Bare minimum required fields
2. **Standard Packages (50)** - Typical real-world packages
3. **Complex Packages (20)** - Multi-version, many dependencies
4. **Edge Case Packages (20)** - Unicode, special chars, extremes

**Total: 100 realistic package fixtures**

### 3.2 Test Data Characteristics

```rust
// Example fixture design
pub struct PackageFixtures {
    // Normal cases
    pub minimal: Vec<Package>,           // 10 packages
    pub standard: Vec<Package>,          // 50 packages
    pub complex: Vec<Package>,           // 20 packages

    // Edge cases
    pub unicode_names: Vec<Package>,     // 5 packages
    pub special_chars: Vec<Package>,     // 5 packages
    pub large_descriptions: Vec<Package>, // 5 packages
    pub extreme_versions: Vec<Package>,  // 5 packages

    // Invalid/malformed (for error testing)
    pub invalid_ids: Vec<String>,        // 10 invalid IDs
    pub invalid_versions: Vec<String>,   // 10 invalid versions
    pub tampered_packages: Vec<Package>, // 5 tampered packages
}
```

---

## 4. Feature Flag Test Strategy

### 4.1 V1 Only (`marketplace-v1`)

**Goal:** Ensure zero regression from current behavior

```rust
#[cfg(feature = "marketplace-v1")]
#[tokio::test]
async fn test_v1_search_exact_match() {
    // V1 backend must produce identical results
}
```

**Test Coverage:**
- ✅ All 7 commands work identically
- ✅ Output format matches exactly
- ✅ Error messages unchanged
- ✅ Performance equivalent

### 4.2 V2 Only (`marketplace-v2`)

**Goal:** Validate RDF/SPARQL implementation

```rust
#[cfg(feature = "marketplace-v2")]
#[tokio::test]
async fn test_v2_sparql_search() {
    // V2 RDF backend with SPARQL queries
}
```

**Test Coverage:**
- ✅ SPARQL query correctness
- ✅ RDF data model validation
- ✅ Cache performance (v3)
- ✅ Signature verification

### 4.3 Parallel Comparison (`marketplace-parallel`)

**Goal:** Prove v1 and v2 produce identical results

```rust
#[cfg(feature = "marketplace-parallel")]
#[tokio::test]
async fn test_parallel_search_consistency() {
    let v1_results = v1_backend.search("query").await;
    let v2_results = v2_backend.search("query").await;
    assert_eq!(v1_results, v2_results);
}
```

**Test Coverage:**
- ✅ Same inputs → same outputs
- ✅ Same errors for same failures
- ✅ Performance comparison (v1 vs v2)

---

## 5. Performance SLOs & Validation

### 5.1 Latency SLOs

| Operation | p50 | p95 | p99 | Max |
|-----------|-----|-----|-----|-----|
| Lookup | <30ms | <100ms | <150ms | <500ms |
| Search | <80ms | <200ms | <300ms | <1000ms |
| Install | <200ms | <500ms | <1000ms | <5000ms |
| List | <50ms | <150ms | <250ms | <1000ms |

### 5.2 Cache SLOs

| Cache Type | Hit Rate | Invalidation Latency |
|------------|----------|---------------------|
| Hot Query Cache | >90% | <10ms |
| Metadata Cache | >80% | <50ms |
| Search Index | >95% | <100ms |

### 5.3 Resource SLOs

| Resource | Limit | Measurement |
|----------|-------|-------------|
| Memory | <500MB | Peak RSS for 1000 packages |
| CPU | <50% | Average during bulk operations |
| Disk | <100MB | RDF store size for 1000 packages |
