Results: 10 failed, 8 skipped, 20 passed (30 total suites) | 23 failed, 127 skipped, 220 passed (370 total tests)

🔴 Critical Test Failures (Immediate Action Required)

1. vector-search-rag-real.test.ts - Test Validation Failure

• Error: expect(testFileContent).not.toContain("jest.mock('../../src/lib/prisma')")
• Root Cause: Test validation is incorrectly detecting mocked content
• Impact: Prevents validation of real integration tests
• Priority: HIGH
• Fix Required: Update test validation logic to properly detect mock usage

2. cache-pgvector-integration.test.ts - PGVector Pool Error

• Error: TypeError: this.pool.end is not a function
• Root Cause: PGVectorClient pool object doesn’t have end() method
• Impact: Database connection cleanup failing
• Priority: HIGH
• Fix Required: Implement proper pool cleanup method

3. collaboration-performance.test.ts - Document Compression Failure

• Error: expect(9011).toBeLessThan(4519) - Compression not working
• Root Cause: Document compression algorithm not reducing size
• Impact: Performance degradation in collaboration features
• Priority: HIGH
• Fix Required: Fix or replace document compression implementation

4. collaboration-performance.test.ts - Performance Degradation

• Error: expect(27.9).toBeLessThan(10) - 27x slower vs 10x limit
• Root Cause: Severe performance regression with document complexity
• Impact: Scalability issues with large documents
• Priority: HIGH
• Fix Required: Optimize document processing algorithms

5. real-vector-db-creation.test.ts - Error Message Validation

• Error: expect(hasExpectedKeyword).toBe(true) - Missing error keywords
• Root Cause: Error messages not containing expected validation keywords
• Impact: Poor error handling user experience
• Priority: MEDIUM
• Fix Required: Improve error message content and validation

6. ai-chat-stream-simple.test.ts - Empty Test Suite

• Error: Your test suite must contain at least one test
• Root Cause: Test file exists but contains no actual tests
• Impact: False positive in test coverage
• Priority: LOW
• Fix Required: Add tests or remove empty file

7. user-provisioning-integration.test.ts - KIND Cluster Missing

• Error: Command failed: kubectl config use-context kind-vibecode-provisioning-test
• Root Cause: KIND cluster not created or context not available
• Impact: Kubernetes integration tests failing
• Priority: MEDIUM
• Fix Required: Ensure KIND cluster setup in test environment

8. datadog-real.test.ts - Error Handling Logic

• Error: expect(202).toBeGreaterThanOrEqual(400) - Wrong status code
• Root Cause: Invalid data returning success (202) instead of error (400+)
• Impact: Incorrect error handling behavior
• Priority: MEDIUM
• Fix Required: Fix API error response logic

9. file-operations-integration.test.ts - Multiple Issues

• Error 1: Missing required configuration parameters
• Error 2: WebSocket coordination timeouts (30s)
• Error 3: File search not finding expected content
• Error 4: ENOENT: no such file or directory, unlink
• Error 5: Event batching not working (averageBatchSize = 1)
• Root Cause: Complex integration test with multiple subsystem failures
• Impact: Core file operations not properly tested
• Priority: HIGH
• Fix Required: Comprehensive file operations system review

🟡 Skipped Tests Analysis (127 Total)

Categories of Skipped Tests:

1. Environment-dependent: Tests requiring specific API keys or services
2. Feature-incomplete: Tests for features not yet implemented
3. Conditionally disabled: Tests disabled due to known issues
4. External dependencies: Tests requiring external services (Redis, Kubernetes, etc.)

Action Required:

• Audit all skipped tests to determine if they should:
  • Be enabled with proper environment setup
  • Be removed if features are deprecated
  • Be converted to unit tests with mocking
  • Be moved to separate integration test suite

🔧 CI/CD Pipeline Issues

Current Problems:

1. Unit tests pass locally but fail in CI - Environment differences
2. Missing environment variables - CI lacks proper test setup
3. Service dependencies - PostgreSQL, Redis, Kubernetes not available in CI
4. Test timeouts - Integration tests taking 64+ seconds
5. Resource conflicts - 23 different CI workflows causing conflicts

Immediate Actions:

1. Fix one CI pipeline at a time (start with unit tests)
2. Add proper test environment setup
3. Separate test categories (unit/integration/e2e)
4. Optimize test performance and parallelization

📊 Test Health Metrics

Current State:

• Unit Tests: ✅ 25/27 suites passing (92.6%)
• Integration Tests: ❌ 20/30 suites passing (66.7%)
• Overall Test Count: 220 passing, 23 failing, 127 skipped
• Test Execution Time: 64.4 seconds (too slow)
• CI/CD Status: ❌ 100% failure rate across all pipelines

Target Goals:

• Unit Tests: 95%+ pass rate
• Integration Tests: 80%+ pass rate
• Test Execution Time: <30 seconds for integration tests
• CI/CD Status: At least one working pipeline
