+
+### 8.2 Test Data Management
+
+**SW-ENV-002**: Test Data Strategy
+- **Data Generation**: Automated test data creation using AutoFixture
+- **Data Seeding**: Consistent seed data for integration tests
+- **Data Privacy**: No production data in test environments
+- **Data Cleanup**: Automatic cleanup after test execution
+
+**Test Data Factory Example**:
+```csharp
+public class TestDataFactory
+{
+    private readonly Fixture _fixture;
+
+    public TestDataFactory()
+    {
+        _fixture = new Fixture();
+        ConfigureFixture();
+    }
+
+    public Account CreateValidAccount(string name = null)
+    {
+        return _fixture.Build<Account>()
+            .With(a => a.Name, name ?? _fixture.Create<string>())
+            .With(a => a.Number, () => GenerateUniqueAccountNumber())
+            .With(a => a.IsActive, true)
+            .Without(a => a.I3D) // Let database generate
+            .Create();
+    }
+
+    public Receipt CreateValidReceipt(int customerI3D)
+    {
+        return _fixture.Build<Receipt>()
+            .With(r => r.CustomerI3D, customerI3D)
+            .With(r => r.State, ReceiptState.Draft)
+            .With(r => r.CreatedAt, DateTime.Now)
+            .Without(r => r.I3D)
+            .Create();
+    }
+}
+```
+
+### 8.3 Continuous Integration Testing
+
+**SW-ENV-003**: CI/CD Test Integration
+- **Build Pipeline**: All tests execute on every commit
+- **Test Reporting**: Comprehensive test result reporting
+- **Coverage Analysis**: Code coverage tracking and reporting
+- **Quality Gates**: Minimum test coverage and pass rate requirements
+
+**CI Pipeline Test Stages**:
+1. **Unit Tests**: Fast feedback (< 5 minutes)
+2. **Integration Tests**: Database and API validation (< 15 minutes)
+3. **System Tests**: End-to-end scenarios (< 30 minutes)
+4. **Performance Tests**: Load and stress testing (< 60 minutes)

+## Test Execution Requirements
+
+### Testing Standards and Practices
+
+**Test Naming Convention**:
+- **Format**: `MethodUnderTest_Scenario_ExpectedBehavior`
+- **Examples**:
+  - `CreateAccount_WithValidData_ShouldReturnSuccess`
+  - `CalculateVAT_WithZeroAmount_ShouldReturnZeroVAT`
+
+**Test Categories**:
+- `[TestCategory("Unit")]` - Fast, isolated unit tests
+- `[TestCategory("Integration")]` - Database and API integration tests
+- `[TestCategory("System")]` - End-to-end workflow tests
+- `[TestCategory("Performance")]` - Load and performance tests
+- `[TestCategory("Security")]` - Security validation tests
+
+**Coverage Requirements**:
+- **Business Logic**: Minimum 85% line coverage
+- **Data Access**: Minimum 75% line coverage
+- **Web Services**: Minimum 80% line coverage
+- **Critical Paths**: 100% coverage for payment and security functions
+
+### Test Reporting and Metrics
