# Task 13: RLS Integration Tests - Concurrent Request Safety Details
|
|
|
|
## Test Summary
|
|
|
|
**Total Tests Created**: 6
|
|
**Status**: Code complete, requires Docker to execute
|
|
|
|
All 6 RLS isolation tests were successfully created and build without errors:
|
|
|
|
1. ✅ Test1_CompleteIsolation_TenantsSeeOnlyTheirData
|
|
2. ✅ Test2_NoContext_NoData_RlsBlocksEverything
|
|
3. ✅ Test3_InsertProtection_CrossTenantInsertBlocked
|
|
4. ✅ Test4_ConcurrentRequests_ConnectionPoolSafety
|
|
5. ✅ Test5_CrossTenantHeaderSpoof_MiddlewareBlocks
|
|
6. ✅ Test6_InterceptorVerification_SetLocalExecuted
|
|
|
|
## Test 4: Concurrent Request Safety (Detailed)
|
|
|
|
**Purpose**: Prove that `SET LOCAL` (transaction-scoped) RLS context is safe with connection pooling under concurrent load.
|
|
|
|
**Implementation**:
|
|
- Seeds 25 work items for Club A, 25 for Club B (total: 50 items)
|
|
- Fires 50 parallel database connections using Task.Run():
|
|
- 25 connections querying as Club A
|
|
- 25 connections querying as Club B
|
|
- Each connection:
|
|
1. Opens new NpgsqlConnection
|
|
2. Executes `SET LOCAL app.current_tenant_id = '<club-id>'`
|
|
3. Queries all work_items (filtered by RLS)
|
|
4. Closes connection (returns to pool)
|
|
|
|
**Expected Results** (when Docker available):
|
|
- All 50 parallel requests complete successfully
|
|
- Every Club A request sees exactly 25 Club A items (no Club B data)
|
|
- Every Club B request sees exactly 25 Club B items (no Club A data)
|
|
- Zero cross-contamination events across 50 concurrent connections
|
|
- Proves: `SET LOCAL` resets per-transaction, preventing tenant leakage in pooled connections
|
|
|
|
**Why This Matters**:
|
|
- EF Core uses connection pooling by default
|
|
- If we used `SET` (session-scoped), tenant context would leak across requests
|
|
- `SET LOCAL` (transaction-scoped) resets on transaction commit/rollback
|
|
- This test proves RLS is production-safe under high concurrency
|
|
|
|
## Current Status
|
|
|
|
**Blocked By**: Docker/Testcontainers not available in development environment
|
|
- Error: "Docker is either not running or misconfigured"
|
|
- Same issue documented in Task 7 learnings
|
|
- Tests compile successfully and are ready to run when Docker available
|
|
|
|
**Workaround for Verification** (when Docker available):
|
|
```bash
|
|
# Start Docker
|
|
docker compose up -d postgres
|
|
|
|
# Run RLS isolation tests
|
|
cd backend
|
|
dotnet test WorkClub.Tests.Integration --filter "FullyQualifiedName~RlsIsolationTests" --verbosity detailed
|
|
```
|
|
|
|
**Expected Outcome** (when Docker works):
|
|
```
|
|
Gesamtzahl Tests: 6
|
|
Bestanden: 6
|
|
Nicht bestanden: 0
|
|
Gesamtzeit: ~30-45 seconds (Testcontainers startup overhead)
|
|
```
|
|
|
|
## Test Infrastructure Used
|
|
|
|
- **Testcontainers PostgreSQL**: Real PostgreSQL 16 Alpine container
|
|
- **Dapper**: Raw SQL execution to bypass EF Core (tests RLS directly)
|
|
- **CustomWebApplicationFactory**: Integration test fixture with TestAuthHandler
|
|
- **IntegrationTestBase**: Provides AuthenticateAs() and SetTenant() helpers
|
|
|
|
## Files Created
|
|
|
|
- `backend/WorkClub.Tests.Integration/MultiTenancy/RlsIsolationTests.cs` (378 lines)
|
|
- 6 comprehensive RLS test scenarios
|
|
- Uses TDD approach: tests written first, verify infrastructure
|
|
- BDD-style comments (Arrange/Act/Assert) for test clarity
|
|
- Concurrent safety test uses Task.Run() + Task.WhenAll() for parallelism
|
|
|
|
## Build Status
|
|
|
|
✅ **Build Successful**: 0 errors, 6 warnings (BouncyCastle transitive dependency - known issue)
|
|
|
|
```bash
|
|
cd backend && dotnet build WorkClub.Tests.Integration/WorkClub.Tests.Integration.csproj
|
|
# Result: Der Buildvorgang wurde erfolgreich ausgeführt. 0 Fehler
|
|
```
|
|
|
|
## Next Steps
|
|
|
|
1. **Immediate**: Fix Docker environment (Colima VM issue) OR use alternative PostgreSQL
|
|
2. **Verify**: Run tests once Docker available: `dotnet test --filter RlsIsolation`
|
|
3. **Expected**: All 6 tests pass, proving multi-tenant RLS isolation works correctly
|
|
4. **Then**: Safe to proceed with API endpoint development (Tasks 14-16)
