# 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`:
```xml
<!-- 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`:

```csharp
// 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)
```sql
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:

```csharp
// 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:

```sql
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
