Test Coverage Implementation Plan

Agentic QE - Claude Flow

Generated: 2025-10-17 Project: /workspaces/agentic-qe-cf/ Current Status: 86.1% test pass rate (329/382 passing), coverage instrumentation broken Reference Report: docs/reports/test-coverage-analysis.md

---

Executive Summary

Current Situation

• Test Pass Rate: 86.1% (329 passing / 53 failing)
• Coverage Metrics: 0% (instrumentation broken - CRITICAL ISSUE)
• Test Files: 96+ test files across unit, integration, and e2e categories
• Main Issues:
  1. Coverage instrumentation not working (0% reported despite 329 passing tests)
  2. 53 failing tests need investigation and fixes
  3. Missing edge case coverage for core modules
  4. Limited integration and performance tests

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:

# 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:

// 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:

// 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:

// 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

      { 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() },

    expect(prediction.isFlaky).toBe(true);
    expect(prediction.confidence).toBeGreaterThan(0.5);

Success Criteria:

• ML model tests pass consistently

open coverage/index.html

Quality Gates

Phase 1 Gate:

• Coverage >40%
• Pass rate >95%
• 0 critical failures

Phase 2 Gate:

• Coverage >60%
• Pass rate 100%
• Integration tests passing

Phase 3 Gate:

• Coverage >75%
• Performance benchmarks met
• Chaos tests passing

Phase 4 Gate:

• Coverage >80%
• All advanced tests passing
• Documentation complete

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

Appendix

Test Quality Standards

Unit Tests:

• 1 test file per source file
• 80%+ coverage per file
• Test all public methods
• Test edge cases and error paths

Integration Tests:

• Test component interactions
• Use real dependencies where possible
• Verify end-to-end workflows
• Include performance assertions

Property-Based Tests:

• 100+ random test cases
• Verify invariants
• Document discovered edge cases
• Use shrinking for failures

Code Examples

See test files in plan above for:

• Edge case testing patterns
• Mock implementation best practices
• Concurrent testing strategies
• Performance benchmarking patterns
• Chaos testing techniques
