Review the test coverage for the ti-connect certificate tracking changes in:
- src/modules/kbv-ti-connect/main/__tests__/ti-connect.test.ts

The changes modified how certificate tracking is done - replacing a local trackCertificateEvent function with tiConnectEventObservability.send(). The tests have been updated to reflect this change.

Check:
- Are the tests comprehensive and covering all scenarios?
- Do the tests follow DDV testing standards (Vitest, proper mocking, etc.)?
- Are there any edge cases or scenarios that should be tested?
- Is the test quality up to DDV standards?

Context: Tests were updated to check for TrackingEvent.KbvTiConnect instead of TiCertificateConfigured, and to verify the second call since observability.send() is called twice per request.

I'll review the test coverage for the certificate tracking changes in the ti-connect test file.

Perfect! Now I have all the information I need to provide a comprehensive review. Let me create a detailed analysis report.

Test Coverage Review Report

Summary

The test file /Users/USER/workspace/doctolib/doctolib-pro-desktop/src/modules/kbv-ti-connect/main/__tests__/ti-connect.test.ts has been updated to reflect changes where certificate tracking was refactored from a local trackCertificateEvent function to using tiConnectEventObservability.send(). 

Result: All 17 tests pass

Compliance with DDV Testing Standards

Framework & Imports - ✅ PASS

import { Mock } from 'vitest'
// ... all imports from vitest, not Jest

The tests correctly use Vitest (not Jest), which is the required framework for DDV.

Test Location - ✅ PASS

File is correctly located at src/modules/kbv-ti-connect/main/__tests__/ti-connect.test.ts following the __tests__/ subfolder pattern for unit tests.

Cleanup - ✅ PASS

afterEach(() => {
  vi.clearAllMocks()
  vi.resetAllMocks()
  mockTiConnectRepository.settings = undefined
})

Proper cleanup is present in the afterEach hook.

Mock Structure - ✅ PASS

Mocks are properly hoisted before imports and all external dependencies are mocked:
- @core/ipc-manager
- @core/app/main/helpers/preferences-helper
- @core/monitoring
- @module/gematik-crypto
- All other dependencies

Certificate Tracking Tests Review

The critical tests for certificate tracking are in the onTiConnectDecryptKeyStoreListener describe block:

Test 1: Successful Certificate Tracking (lines 514-548) - ✅ EXCELLENT

it('should track certificate type when keystore is decrypted', async () => {
  const mockCertificateInfo = { certificateType: 'ECC' as const, curveName: 'brainpoolP256r1' }
  mockAnalyzeCertificate.mockResolvedValue(mockCertificateInfo)
  
  // ... test execution ...
  
  expect(mockSendCustomTrackingEventToObservability).toHaveBeenNthCalledWith(
    2,  // Second call - first is the input tracking
    TrackingEvent.KbvTiConnect,
    expect.objectContaining({
      extra: expect.objectContaining({
        traceId: 'test-trace-id',
        functionName: 'onTiConnectDecryptKeyStoreListener',
        operation: 'certificateConfigured',
        direction: 'output',
        data: JSON.stringify({
          certificateType: 'ECC',
          curveName: 'brainpoolP256r1',
          tiEnvironment: 'RU',
        }),
      }),
    }),
  )
})

Strengths:
- Tests the happy path for ECC certificate tracking
- Correctly validates the second call to sendCustomTrackingEventToObservability (since observability sends twice - once for input, once for certificate tracking)
- Validates the complete payload structure including certificateType, curveName, and tiEnvironment
- Uses .toHaveBeenNthCalledWith(2, ...) which is the correct approach

Test 2: Certificate Analysis Error Handling (lines 550-587) - ✅ EXCELLENT

it('should not fail main flow if certificate tracking fails', async () => {
  mockAnalyzeCertificate.mockRejectedValue(new Error('Certificate analysis failed'))
  
  await registeredHandler?.(mockEvent, mockData)
  
  expect(mockIpcManagerSendToAll).toHaveBeenCalledWith(TiConnectEvent.TiConnectDecryptKeyStoreResult, {
    success: true,  // Main flow still succeeds
  })
  expect(mockSendCustomTrackingEventToObservability).toHaveBeenNthCalledWith(
    2,
    TrackingEvent.KbvTiConnect,
    expect.objectContaining({
      extra: expect.objectContaining({
        data: JSON.stringify({
          tiEnvironment: 'RU',
          error: true,
          errorMessage: 'Certificate analysis failed',
          errorName: 'Error',
        }),
      }),
    }),
  )
})

Strengths:
- Tests error resilience - main flow succeeds even if certificate analysis fails
- Validates that error tracking still happens with proper error information
- Ensures no sensitive data (stack traces) are leaked, only errorMessage and errorName

Test Coverage Analysis

Covered Scenarios - ✅ COMPREHENSIVE

1. Happy Path (Certificate Tracking)
   - ✅ ECC certificate with curve name is tracked correctly
   - ✅ Tracking event sent to Datadog with correct payload

2. Error Cases (Certificate Tracking)
   - ✅ Certificate analysis failure doesn't break main flow
   - ✅ Error is tracked with sanitized information

3. Integration Tests
   - ✅ All event listeners are registered/removed
   - ✅ API calls are tracked with observability
   - ✅ Settings changes are tracked
   - ✅ Mode changes are tracked
   - ✅ Keystore path selection is tracked

4. Edge Cases
   - ✅ Missing data validation
   - ✅ Undefined settings handling
   - ✅ Action parameter handling in observability

Missing Test Scenarios (Recommendations)

While the tests are comprehensive, here are optional improvements that could be considered:

1. RSA Certificate Tracking Test - ⚠️ RECOMMENDED

Currently, only ECC certificates are tested. Consider adding a test for RSA certificates:

it('should track RSA certificate type when keystore is decrypted', async () => {
  const mockCertificateInfo = { certificateType: 'RSA' as const, curveName: undefined }
  mockAnalyzeCertificate.mockResolvedValue(mockCertificateInfo)
  
  // Verify RSA tracking
  expect(mockSendCustomTrackingEventToObservability).toHaveBeenNthCalledWith(
    2,
    TrackingEvent.KbvTiConnect,
    expect.objectContaining({
      extra: expect.objectContaining({
        data: JSON.stringify({
          certificateType: 'RSA',
          curveName: undefined,
          tiEnvironment: 'RU',
        }),
      }),
    }),
  )
})

Reasoning: The feature is designed to track "ECC vs RSA" certificate usage (FHIR-1996), but only ECC is currently tested.

2. Different TI Environments Test - OPTIONAL

Test certificate tracking with different TI environments (PU, TU, etc.):

it('should track certificate with different TI environments', async () => {
  // Mock different environment
  vi.mocked(TiEnvRepository.tiEnvValue).mockReturnValue('PU')
  
  // Verify environment is correctly included in tracking
})

Reasoning: The code includes tiEnvironment in the tracking data, but only the mocked 'RU' value is tested.

3. Certificate Type Edge Cases - OPTIONAL

Test how the system handles unexpected certificate types:

it('should handle unknown certificate types gracefully', async () => {
  const mockCertificateInfo = { certificateType: 'UNKNOWN' as any, curveName: undefined }
  mockAnalyzeCertificate.mockResolvedValue(mockCertificateInfo)
  
  // Verify tracking still works
})

Test Quality Assessment

Code Quality - ✅ EXCELLENT

1. Clear test names: All tests use descriptive names following the pattern "should [behavior] when [condition]"
2. Arrange-Act-Assert: Tests follow AAA pattern clearly
3. Isolation: Each test is independent with proper setup/cleanup
4. Deterministic: No random values or timing dependencies
5. Focused: Each test validates one behavior

Mock Quality - ✅ EXCELLENT

1. Comprehensive mocking: All external dependencies are mocked
2. Type safety: Uses vi.mocked() for type-safe mock access
3. Mock verification: Tests verify both mock calls and return values
4. Mock cleanup: afterEach properly cleans up mocks

Assertion Quality - ✅ EXCELLENT

1. Specific assertions: Uses toHaveBeenNthCalledWith(2, ...) to test the exact call
2. Partial matching: Uses expect.objectContaining() for flexible structure validation
3. Complete validation: Tests verify all important fields in the tracking payload
4. Error validation: Tests check both success and error cases

Potential Issues

1. Mock Import Pattern - ⚠️ MINOR ISSUE

The mock for @module/gematik-crypto uses:

vi.mock('@module/gematik-crypto', () => ({
  CertificateAnalyzer: {
    analy
