## Phase 1: Critical Fixes (Week 1)

### Priority: CRITICAL
**Goal**: Fix coverage instrumentation and failing tests
**Timeline**: Days 1-5 (40 hours)
**Target**: 40% coverage, 95%+ test pass rate

### Task Breakdown

#### TEST-001: Fix Coverage Instrumentation ⚠️ BLOCKING
**Priority**: CRITICAL
**Agent**: coder
**Effort**: 4-6 hours
**Dependencies**: None
**Blockers**: None

**Problem**: Coverage reports show 0% despite 329 passing tests

**Root Cause Investigation**:
```bash
# Check jest configuration
cat jest.config.js

# Verify coverage collection
npm run test -- --coverage --verbose

# Check if transform is working
npm run test -- --no-cache --verbose
```

**Implementation**:
```typescript
// jest.config.js - Verify coverage configuration
module.exports = {
  preset: 'ts-jest',
  testEnvironment: 'node',
  roots: ['<rootDir>/tests'],

  // CRITICAL: Ensure coverage collection is enabled
  collectCoverage: true,
  collectCoverageFrom: [
    'src/**/*.{ts,tsx}',
    '!src/**/*.d.ts',
    '!src/**/*.test.ts',
    '!src/**/__mocks__/**',
    '!src/**/types/**'
  ],

  // Coverage thresholds
  coverageThresholds: {
    global: {
      statements: 70,
      branches: 70,
      functions: 70,
      lines: 70
    }
  },

  // Coverage reporters
  coverageReporters: ['text', 'lcov', 'html', 'json-summary'],
  coverageDirectory: 'coverage',

  // Transform configuration
  transform: {
    '^.+\\.tsx?$': ['ts-jest', {
      tsconfig: 'tsconfig.json',
      diagnostics: true
    }]
  },

  // Module resolution
  moduleNameMapper: {
    '^@/(.*)$': '<rootDir>/src/$1'
  }
};
```

**Success Criteria**:
- [ ] Coverage report shows actual percentages (not 0%)
- [ ] Coverage HTML report generated in `/coverage` directory
- [ ] Coverage badges update with real metrics
- [ ] `npm run test:coverage` completes without errors

**Files to Modify**:
- `/workspaces/agentic-qe-cf/jest.config.js`
- `/workspaces/agentic-qe-cf/package.json` (test scripts)

#### TEST-002: Fix Failing EventBus Tests
**Priority**: CRITICAL
**Agent**: tester
**Effort**: 3-4 hours
**Dependencies**: TEST-001

**Problem**: EventBus test failing on initialization count

**Error**:
```
Expected number of calls: 2
Received number of calls: 4
```

**Root Cause**: Test expects logger.info() called once, but it's called multiple times during initialization

**Implementation**:
```typescript
// tests/unit/EventBus.test.ts - Fix initialization test
describe('EventBus › Initialization', () => {
  test('should handle multiple initialization calls gracefully', async () => {
    const mockLogger = {
      info: jest.fn(),
      warn: jest.fn(),
      error: jest.fn(),
      debug: jest.fn()
    };

    const newEventBus = new EventBus();
    newEventBus.setLogger(mockLogger);

    await newEventBus.initialize(); // First call
    const firstCallCount = mockLogger.info.mock.calls.length;

    await newEventBus.initialize(); // Second call should be idempotent
    const secondCallCount = mockLogger.info.mock.calls.length;

    // Second initialization should not log additional messages
    expect(secondCallCount).toBe(firstCallCount);
    expect(newEventBus.isInitialized()).toBe(true);
  });
});
```

**Success Criteria**:
- [ ] Test passes consistently
- [ ] Idempotent initialization verified
- [ ] No regression in other EventBus tests

**Files to Modify**:
- `/workspaces/agentic-qe-cf/tests/unit/EventBus.test.ts`

#### TEST-003: Fix FleetManager Database Initialization
**Priority**: CRITICAL
**Agent**: coder
**Effort**: 4-6 hours
**Dependencies**: TEST-001

**Problem**: `this.database.initialize is not a function`

**Root Cause**: Mock database object missing `initialize()` method

**Implementation**:
```typescript
// tests/unit/fleet-manager.test.ts - Fix database mock
describe('FleetManager', () => {
  let mockDatabase: any;
  let mockEventBus: EventEmitter;
  let fleetManager: FleetManager;

  beforeEach(() => {
    // Create complete database mock
    mockDatabase = {
      initialize: jest.fn().mockResolvedValue(undefined),
      close: jest.fn().mockResolvedValue(undefined),
      store: jest.fn().mockResolvedValue(undefined),
      retrieve: jest.fn().mockResolvedValue(null),
      query: jest.fn().mockResolvedValue([]),
      delete: jest.fn().mockResolvedValue(true),
      stats: jest.fn().mockResolvedValue({
        totalEntries: 0,
        totalHints: 0,
        totalEvents: 0,
        partitions: []
      })
    };

    mockEventBus = new EventEmitter();

    fleetManager = new FleetManager({
      database: mockDatabase,
      eventBus: mockEventBus,
      maxAgents: 10
    });
  });

  test('should initialize fleet manager successfully', async () => {
    await fleetManager.initialize();

    expect(mockDatabase.initialize).toHaveBeenCalledTimes(1);
    expect(fleetManager.getStatus().initialized).toBe(true);
  });
});
```

**Success Criteria**:
- [ ] All FleetManager tests pass
- [ ] Database initialization verified
- [ ] Proper error handling tested

#### TEST-004: Fix FlakyTestDetector ML Model Tests
**Priority**: HIGH
**Agent**: tester
**Effort**: 3-4 hours
**Dependencies**: TEST-001

**Problem**: ML model tests may be failing due to non-deterministic behavior

**Implementation**:
```typescript
// tests/unit/learning/FlakyTestDetector.test.ts - Improve test reliability
describe('FlakyTestDetector', () => {
  let detector: FlakyTestDetector;

  beforeEach(() => {
    // Use fixed seed for deterministic testing

      threshold: 0.7,
      minSamples: 10
    });
  });

      { features: [0, 1, 0.1, 50], flaky: false },
      { features: [1, 1, 0.8, 200], flaky: true },
      // ... more training data
    ];

    const result = await detector.trainModel(trainingData);

    expect(result.accuracy).toBeGreaterThanOrEqual(0.7);
    expect(result.accuracy).toBeLessThanOrEqual(1.0);

    // With fixed seed, accuracy should be consistent
    expect(result.accuracy).toBeCloseTo(0.85, 1); // Allow 0.1 variance
  });

  test('should detect flaky tests with confidence scores', async () => {
    const testExecutions = [
      { duration: 100, passed: true, timestamp: Date.now() },
      { duration: 105, passed: false, timestamp: Date.now() + 1000 },
      { duration: 98, passed: true, timestamp: Date.now() + 2000 },
      { duration: 102, passed: false, timestamp: Date.now() + 3000 }
    ];

    const prediction = await detector.predictFlakiness(testExecutions);

    expect(prediction.isFlaky).toBe(true);
    expect(prediction.confidence).toBeGreaterThan(0.5);
    expect(prediction.features).toBeDefined();
  });
});
```

**Success Criteria**:
- [ ] ML model tests pass consistently
- [ ] Deterministic behavior with fixed seed
- [ ] Confidence scores within expected ranges

## Risk Mitigation

### High-Risk Items

1. **Coverage Instrumentation Fix** (TEST-001)
   - **Risk**: Configuration changes break existing tests
   - **Mitigation**: Test in isolation, incremental rollout
   - **Rollback Plan**: Git revert jest.config.js changes

2. **FleetManager Database Mock** (TEST-003)
   - **Risk**: Mock doesn't match real SwarmMemoryManager interface
   - **Mitigation**: Use type-safe mocks, integration tests
   - **Rollback Plan**: Revert to previous mock implementation

3. **Multi-Agent Load Test** (TEST-006)
   - **Risk**: Memory leaks or performance degradation
   - **Mitigation**: Monitor memory usage, incremental scaling
   - **Rollback Plan**: Reduce agent count, increase timeouts

### Contingency Plans

**If Week 1 Slips**:
- Focus on TEST-001 (coverage) and TEST-003 (FleetManager)
- Defer TEST-005 (edge cases) to Week 2

**If Week 2 Slips**:
- Complete TEST-006 (load testing) only
- Move TEST-007, TEST-008 to Week 3

**If Coverage Target Not Met**:
- Prioritize high-value modules (BaseAgent, SwarmMemoryManager, EventBus)
- Focus on branch coverage over statement coverage
- Add focused unit tests for uncovered lines
