- OIDC mock provider with token compatibility improvements
- Better test data separation between mock and production code
✅ IMPROVED POLICY VALIDATION:
- Trust policy validation separate from resource policies
- Enhanced policy engine test coverage
- Better policy document structure validation
✅ REFINED STS SERVICE:
- Improved session management and validation
- Better error handling and edge cases
- Enhanced test coverage for complex scenarios
These changes provide the foundation for the integrated IAM system.
Phase 2 of Advanced IAM Development Plan - STS Implementation
✅ WHAT WAS CREATED:
- Complete STS service interface with comprehensive test coverage
- AssumeRoleWithWebIdentity (OIDC) and AssumeRoleWithCredentials (LDAP) APIs
- Session token validation and revocation functionality
- Multiple session store implementations (Memory + Filer)
- Professional AWS STS-compatible API structures
✅ TDD RED PHASE RESULTS:
- All tests compile successfully - interfaces are correct
- Basic initialization tests PASS as expected
- Feature tests FAIL with honest 'not implemented yet' errors
- Production code doesn't lie about its capabilities
📋 COMPREHENSIVE TEST COVERAGE:
- STS service initialization and configuration validation
- Role assumption with OIDC tokens (various scenarios)
- Role assumption with LDAP credentials
- Session token validation and expiration
- Session revocation and cleanup
- Mock providers for isolated testing
🎯 NEXT STEPS (GREEN Phase):
- Implement real JWT token generation and validation
- Build role assumption logic with provider integration
- Create session management and storage
- Add security validations and error handling
This establishes the complete STS foundation with failing tests
that will guide implementation in the GREEN phase.
PROBLEM FIXED:
- LDAP provider had hardcoded test credentials ('testuser:testpass')
- Production code contained mock user data and authentication logic
- Methods returned fake test data instead of honest 'not implemented' errors
SOLUTION:
- Removed all test data and mock logic from production LDAPProvider
- Production methods now return proper 'not implemented yet' errors
- Created MockLDAPProvider with comprehensive test data isolation
- Added proper TODO comments explaining what needs real implementation
RESULTS:
- Clean separation: production code vs test utilities
- Tests fail appropriately when features aren't implemented
- Clear roadmap for implementing real LDAP integration
- Professional code that doesn't lie about capabilities
Next: Move to Phase 2 (STS implementation) of the Advanced IAM plan
WHAT WAS WRONG:
- Production code contained hardcoded test data and mock implementations
- ValidateToken() had if statements checking for 'expired_token', 'invalid_token'
- GetUserInfo() returned hardcoded mock user data
- This violates separation of concerns and clean code principles
WHAT WAS FIXED:
- Removed all test data and mock logic from production OIDC provider
- Production code now properly returns 'not implemented yet' errors
- Created MockOIDCProvider with all test data isolated
- Tests now fail appropriately when features are not implemented
RESULT:
- Clean separation between production and test code
- Production code is honest about its current implementation status
- Test failures guide development (true TDD RED/GREEN cycle)
- Foundation ready for real OIDC/JWT implementation
