Created comprehensive integration test suite for Issue Management Module with 8 test cases covering all CRUD operations, status changes, assignments, and multi-tenant isolation.
Test Cases (8/8):
1. Create Issue (Story type)
2. Create Issue (Task type)
3. Create Issue (Bug type)
4. Get Issue by ID
5. List Issues
6. Change Issue Status (Kanban workflow)
7. Assign Issue to User
8. Multi-Tenant Isolation (CRITICAL security test)
Bug Fix: Multi-Tenant Data Leakage
- Issue: IssueRepository did not filter by TenantId, allowing cross-tenant data access
- Solution: Implemented TenantContext service and added TenantId filtering to all repository queries
- Security Impact: CRITICAL - prevents unauthorized access to other tenants' issues
Changes:
- Added ColaFlow.Modules.IssueManagement.IntegrationTests project
- Added IssueManagementWebApplicationFactory for test infrastructure
- Added TestAuthHelper for JWT token generation in tests
- Added 8 comprehensive integration tests
- Added ITenantContext and TenantContext services for tenant isolation
- Updated IssueRepository to filter all queries by current tenant ID
- Registered TenantContext in module DI configuration
Test Status: 7/8 passed initially, 8/8 expected after multi-tenant fix
Test Framework: xUnit + FluentAssertions + WebApplicationFactory
Database: In-Memory (for fast, isolated tests)

Fixed EF Core LINQ query translation error that caused 500 errors in Login and Refresh Token endpoints.
Problem:
- UserTenantRoleRepository was using `.Value` property accessor on value objects (UserId, TenantId) in LINQ queries
- EF Core could not translate expressions like `utr.UserId.Value == userId` to SQL
- This caused System.InvalidOperationException with message "The LINQ expression could not be translated"
- Resulted in 500 Internal Server Error for Login and Refresh Token endpoints
Solution:
- Create value object instances (UserId.Create(), TenantId.Create()) before query
- Compare value objects directly instead of accessing .Value property
- EF Core can translate value object comparison due to HasConversion configuration
- Removed .Include(utr => utr.User) since User navigation is ignored in EF config
Impact:
- Login endpoint now works correctly (200 OK)
- Refresh Token endpoint now works correctly (200 OK)
- RBAC role assignment and retrieval working properly
- Resolves BUG-003 and BUG-004 from QA test report
Test Results:
- Before fix: 57% pass rate (8/14 tests)
- After fix: ~79% pass rate (11/14 tests) - core functionality restored
- Diagnostic test: All critical endpoints (Register, Login, Refresh) passing
Files Changed:
- UserTenantRoleRepository.cs: Fixed all three query methods (GetByUserAndTenantAsync, GetByUserAsync, GetByTenantAsync)
