Day 5 Integration Test Report

Project: ColaFlow Test Date: 2025-11-03 Tested By: QA Agent Environment: Development (.NET 9, PostgreSQL) Test Scope: Day 5 - Refresh Token Mechanism + RBAC System

---

Executive Summary

Test Execution Status: BLOCKED

Critical Issues Found: 2 Severity: CRITICAL - DO NOT DEPLOY

The Day 5 integration testing was BLOCKED due to two critical bugs that prevent the API from starting or accepting requests:

1. EF Core Version Mismatch (FIXED during testing)
2. Database Schema Migration Error (BLOCKING - NOT FIXED)

---

Test Environment

Component	Version	Status
.NET SDK	9.0.305	✅ Working
PostgreSQL	Latest	✅ Working
EF Core	9.0.10 (after fix)	✅ Working
API Server	localhost:5167	❌ FAILED (Schema error)
Database	colaflow_dev	⚠️ Schema issues

---

Test Execution Timeline

1. 16:00 - Started API server → Failed with EF Core assembly error
2. 16:05 - Identified EF Core version mismatch bug
3. 16:10 - Fixed EF Core versions, rebuilt solution → Build succeeded
4. 16:15 - Restarted API server → Failed with foreign key constraint violation
5. 16:20 - Identified database schema migration bug (duplicate columns)
6. 16:25 - Created comprehensive test scripts
7. 16:30 - Testing BLOCKED - Cannot proceed without schema fix

---

Critical Bugs Found

BUG-001: EF Core Version Mismatch (FIXED)

Severity: CRITICAL Status: ✅ FIXED Impact: API could not start - assembly binding failure

Description

The ProjectManagement module was using EF Core 9.0.0 while the Identity module was using EF Core 9.0.10, causing runtime assembly binding errors.

Error Message

System.IO.FileNotFoundException: Could not load file or assembly
'Microsoft.EntityFrameworkCore.Relational, Version=9.0.10.0,
Culture=neutral, PublicKeyToken=adb9793829ddae60'.
The system cannot find the file specified.

Root Cause

Inconsistent package versions across modules:

• Identity Module: Microsoft.EntityFrameworkCore 9.0.10
• ProjectManagement Module: Microsoft.EntityFrameworkCore 9.0.0

Steps to Reproduce

1. Start API server: dotnet run --project src/ColaFlow.API
2. Make any API request (e.g., POST /api/tenants/register)
3. Observe 500 Internal Server Error with assembly loading exception

Fix Applied

Updated ColaFlow.Modules.ProjectManagement.Infrastructure.csproj:

<!-- BEFORE -->
<PackageReference Include="Microsoft.EntityFrameworkCore" Version="9.0.0" />
<PackageReference Include="Microsoft.EntityFrameworkCore.Relational" Version="9.0.0" />
<PackageReference Include="Npgsql.EntityFrameworkCore.PostgreSQL" Version="9.0.2" />

<!-- AFTER -->
<PackageReference Include="Microsoft.EntityFrameworkCore" Version="9.0.10" />
<PackageReference Include="Microsoft.EntityFrameworkCore.Relational" Version="9.0.10" />
<PackageReference Include="Npgsql.EntityFrameworkCore.PostgreSQL" Version="9.0.4" />

Verification

• ✅ Solution rebuilds successfully
• ✅ No assembly binding warnings
• ✅ API server starts without assembly errors

BUG-002: Database Schema Migration Error (BLOCKING)

Severity: CRITICAL Status: ❌ NOT FIXED Impact: All tenant registration requests fail with foreign key constraint violation

Description

The AddUserTenantRoles migration generated duplicate columns in the identity.user_tenant_roles table:

• Value object columns: user_id, tenant_id (used by application code)
• Navigation property columns: user_id1, tenant_id1 (generated by EF Core)

Foreign key constraints reference the wrong columns (user_id1, tenant_id1), but the application inserts into user_id and tenant_id, causing violations.

Error Message

Npgsql.PostgresException: 23503: insert or update on table "user_tenant_roles"
violates foreign key constraint "FK_user_tenant_roles_tenants_tenant_id1"

Detail: Detail redacted as it may contain sensitive data.
Specify 'Include Error Detail' in the connection string to include this information.

Root Cause

Incorrect EF Core configuration in UserTenantRoleConfiguration.cs:

// Value object mapping (Lines 36-48)
builder.Property(utr => utr.UserId)
    .HasColumnName("user_id")  // ← Mapped to user_id
    .HasConversion(...);

builder.Property(utr => utr.TenantId)
    .HasColumnName("tenant_id")  // ← Mapped to tenant_id
    .HasConversion(...);

// Foreign key mapping (Lines 51-59)
builder.HasOne(utr => utr.User)
    .WithMany()
    .HasForeignKey("user_id");  // ← EF Core creates shadow property user_id1

builder.HasOne(utr => utr.Tenant)
    .WithMany()
    .HasForeignKey("tenant_id");  // ← EF Core creates shadow property tenant_id1

Migration Schema (Actual)

CREATE TABLE identity.user_tenant_roles (
    id uuid PRIMARY KEY,
    user_id uuid NOT NULL,         -- Application uses this
    tenant_id uuid NOT NULL,       -- Application uses this
    role varchar(50) NOT NULL,
    assigned_at timestamp NOT NULL,
    assigned_by_user_id uuid,
    user_id1 uuid NOT NULL,        -- Foreign key points to this!
    tenant_id1 uuid NOT NULL,      -- Foreign key points to this!

    FOREIGN KEY (user_id1) REFERENCES users(id),    -- Wrong column!
    FOREIGN KEY (tenant_id1) REFERENCES tenants(id) -- Wrong column!
);

Steps to Reproduce

1. Start API server
2. Call POST /api/tenants/register with valid tenant data
3. Observe 500 Internal Server Error
4. Check logs: foreign key constraint violation on FK_user_tenant_roles_tenants_tenant_id1

Impact Assessment

• ❌ Tenant registration: BROKEN
• ❌ User login: N/A (cannot test without tenants)
• ❌ Refresh token: N/A (cannot test without login)
• ❌ RBAC: N/A (cannot test without tenant registration)
• ❌ All Day 5 features: BLOCKED

Recommended Fix

Option 1: Fix Entity Configuration (Recommended)

Update UserTenantRoleConfiguration.cs to properly map foreign keys:

// Remove HasForeignKey() calls, let EF Core infer from properties
builder.HasOne(utr => utr.User)
    .WithMany()
    .HasPrincipalKey(u => u.Id)
    .HasForeignKey(utr => utr.UserId)  // Use property, not string
    .OnDelete(DeleteBehavior.Cascade);

builder.HasOne(utr => utr.Tenant)
    .WithMany()
    .HasPrincipalKey(t => t.Id)
    .HasForeignKey(utr => utr.TenantId)  // Use property, not string
    .OnDelete(DeleteBehavior.Cascade);

Option 2: Fix Migration Manually

Edit migration file or create new migration to drop and recreate table with correct schema:

DROP TABLE IF EXISTS identity.user_tenant_roles CASCADE;

CREATE TABLE identity.user_tenant_roles (
    id uuid PRIMARY KEY,
    user_id uuid NOT NULL REFERENCES identity.users(id) ON DELETE CASCADE,
    tenant_id uuid NOT NULL REFERENCES identity.tenants(id) ON DELETE CASCADE,
    role varchar(50) NOT NULL,
    assigned_at timestamp with time zone NOT NULL,
    assigned_by_user_id uuid,
    UNIQUE(user_id, tenant_id)
);

CREATE INDEX ix_user_tenant_roles_user_id ON identity.user_tenant_roles(user_id);
CREATE INDEX ix_user_tenant_roles_tenant_id ON identity.user_tenant_roles(tenant_id);
CREATE INDEX ix_user_tenant_roles_role ON identity.user_tenant_roles(role);

Then apply migration: dotnet ef database update --context IdentityDbContext

Conclusion

Overall Verdict: ❌ TESTING BLOCKED - DO NOT DEPLOY

Day 5 implementation CANNOT BE DEPLOYED due to critical database schema error (BUG-002) that prevents all tenant registration and RBAC functionality.

Key Findings

1. ✅ Code Quality: Implementation follows Clean Architecture and best practices
2. ✅ EF Core Issue: Version mismatch fixed during testing (BUG-001)
3. ❌ Database Schema: Critical foreign key constraint error (BUG-002)
4. ❌ Testing: 0% test coverage - all tests blocked
5. ❌ Functionality: Core features cannot be verified

Next Steps

1. URGENT: Fix BUG-002 (database schema migration)
2. Apply corrected migration to database
3. Restart API server
4. Execute full test suite
5. Verify pass rate ≥ 95%
6. Document actual test results

Timeline Estimate

• Bug Fix: 30 minutes
• Migration: 10 minutes
• Testing: 45 minutes
• Documentation: 15 minutes
• Total: ~2 hours

Risk Assessment

Current Risk Level: 🔴 CRITICAL

• ❌ Cannot register tenants
• ❌ Cannot test any Day 5 features
• ❌ Day 4 regression status unknown
• ❌ Database integrity compromised

Post-Fix Risk Level (estimated): 🟡 MEDIUM

• ⚠️ Needs comprehensive testing
• ⚠️ Regression testing required
• ⚠️ No automated tests yet
