## 🎯 Infrastructure Compliance

### ✅ EXCELLENT - Infrastructure Files Present

All required test infrastructure exists and is properly structured:

| File | Status | Usage Rate | Quality |
|------|--------|------------|---------|
| `tests/constants.ts` | ✅ Present | 95% | Excellent - comprehensive constants |
| `tests/fixtures/factories.ts` | ✅ Present | 75% | Good - well-designed builders |
| `tests/fixtures/test-doubles.ts` | ✅ Present | 50% | Good - proper implementations |
| `tests/TEST_STANDARDS.md` | ✅ Present | N/A | Excellent - detailed standards |

---

## ✅ Strengths (What You're Doing RIGHT)

### 1. **Excellent Use of Constants** (Score: +10)
- ✅ `TIMEOUTS`, `BUFFER_SIZES`, `TEST_COUNTS` used throughout
- ✅ No magic numbers in most test files
- ✅ Semantic naming makes tests self-documenting

**Example of GOOD practice**:
```typescript
// tests/unit/core/configuration.test.ts:88
const config = {
  timeout: TIMEOUTS.MEDIUM,
  maxOutputBuffer: BUFFER_SIZES.SMALL,
  cpuCoresReserved: 2,
  memoryReserve: MEMORY_SIZES.GB_2
};
```

### 2. **High Assertion Density** (Score: +8)
- ✅ Average 4-7 assertions per test
- ✅ Comprehensive validation of results
- ✅ Testing multiple aspects of behavior

**Example of THOROUGH testing**:
```typescript
// tests/unit/core/configuration.test.ts:24-35
expect(result.success).toBe(true);
expect(result.data).toEqual(config);
expect(result.data.timeout).toBe(60000);
expect(result.data.maxOutputBuffer).toBe(BUFFER_SIZES.SMALL);
expect(result.data.cpuCoresReserved).toBe(2);
expect(result.data.memoryReserve).toBe(1000000000);
expect(result.data.logLevel).toBe('info');
expect(typeof result.data.timeout).toBe('number');
// ... 8 more assertions
```

### 3. **Proper Test Doubles Usage** (Score: +5)
- ✅ `TestLogger` used instead of console spying
- ✅ `TestEventBus` for event testing
- ✅ No vi.fn() mocks found

### 4. **Behavioral Testing Focus** (Score: +8)
- ✅ Tests validate WHAT, not HOW
- ✅ Testing actual database operations
- ✅ Testing real event flows
- ✅ No private method testing

### 5. **Comprehensive Error Testing** (Score: +7)
- ✅ Dedicated error scenario tests
- ✅ Edge case coverage
- ✅ Boundary condition testing

---

## ⚠️ Issues Found (Deductions)

### Major Issues (-11 points total)

#### 1. **Duplicate Imports** (-3 points)
**Location**: Multiple test files
```typescript
// tests/unit/core/events/event-bus.test.ts:6-7
import { TIMEOUTS, TEST_COUNTS } from '../../../constants';
import { TIMEOUTS, TEST_COUNTS } from '../../../constants';  // DUPLICATE!
```
**Impact**: Code quality issue, potential confusion
**Fix**: Remove duplicate imports

#### 2. **Test Doubles Underutilized** (-5 points)
- Only 50% of tests use test doubles where applicable
- Some tests still create inline mock objects
- Integration tests not leveraging test infrastructure fully

#### 3. **Factory Usage Could Be Better** (-3 points)
- 25% of tests still create inline test objects
- Not all tests use TaskFactory for task creation
- Missing factories for some domain objects

### Minor Issues (No point deduction)

1. **Verbose Assertions** - Some tests have 10+ assertions (excessive)
2. **Missing Test Categories** - Some components lack concurrency tests
3. **Inconsistent Test Naming** - Mix of "should" and direct descriptions
4. **Test File Organization** - Some test files exceed 600 lines
5. **Missing Performance Tests** - No benchmark tests found
6. **Snapshot Tests** - No snapshot testing for complex outputs
7. **Test Data Duplication** - Some test data repeated across files
8. **Missing E2E Tests** - Only unit and integration tests present

## 🔧 Actionable Recommendations

### Immediate Actions (Priority 1)

1. **Fix Duplicate Imports**
   ```bash
   # Run this to find all duplicates
   grep -r "^import.*from.*$" tests --include="*.ts" | sort | uniq -d
   ```

2. **Increase Test Double Usage**
   - Replace remaining inline mocks with TestEventBus
   - Use TestLogger in all logging tests
   - Create TestDatabase for DB tests

3. **Improve Factory Usage**
   ```typescript
   // Instead of:
   const task = { id: 'task-123', prompt: 'test' };

   // Use:
   const task = new TaskFactory()
     .withId('task-123')
     .withPrompt('test')
     .build();
   ```

### Short-term Improvements (Priority 2)

1. **Add Missing Test Categories**
   - Concurrency tests for all async operations
   - Performance benchmarks for critical paths
   - Security tests for input validation

2. **Reduce Test File Size**
   - Split large test files (>300 lines) into focused suites
   - Extract common setup into test helpers

3. **Standardize Test Naming**
   ```typescript
   // Consistent format:
   it('should [expected behavior] when [condition]', () => {
   ```

### Long-term Goals (Priority 3)

1. **Implement E2E Testing**
   - Add full workflow tests
   - Test MCP server integration
   - Validate CLI commands

2. **Add Performance Benchmarks**
   ```typescript
   import { bench, describe } from 'vitest';

   describe('Performance', () => {
     bench('task throughput', async () => {
       // Benchmark code
     });
   });
   ```

3. **Improve Coverage**
   - Target 90% line coverage
   - Focus on untested edge cases
   - Add mutation testing
