+

+
+## Technical Decisions
+
+### 1. Test Framework: xUnit
+- **Rationale**: .NET standard, parallel execution, good VS integration
+- **Benefits**: Fast, reliable, well-documented
+
+### 2. Assertion Library: FluentAssertions
+- **Rationale**: Readable assertions, better error messages
+- **Example**: `user.Status.Should().Be(UserStatus.Active);`
+
+### 3. Mocking Framework: Moq
+- **Rationale**: Industry standard, easy to use, good documentation
+- **Usage**: Application layer handler tests
+
+### 4. Test Organization
+- **Structure**: Mirrors source code structure
+- **Naming**: `{Entity/Feature}Tests.cs`
+- **Method naming**: `{Method}_{Scenario}_Should{ExpectedResult}`
+
+---
+
+## Key Insights & Lessons
+
+### 1. Domain Enum Values
+- **Issue**: Tests initially failed due to incorrect TenantRole enum values
+- **Solution**: Used actual enum values (`TenantMember` instead of `Member`)
+- **Learning**: Always verify domain model before writing tests
+
+### 2. Idempotent Operations
+- **Importance**: Multiple tests verify idempotent behavior (e.g., VerifyEmail)
+- **Benefit**: Prevents duplicate event raising and ensures state consistency
+
+### 3. Token Security
+- **Pattern**: All tokens use hash + expiration + single-use enforcement
+- **Tests**: Comprehensive validation of security properties
+
+### 4. Rate Limiting Design
+- **Approach**: Database-backed for restart persistence
+- **Tests**: Window expiration, attempt counting, email normalization
+

+

+6. Add performance benchmarks (2 hours)
+7. Create test infrastructure (builders, fixtures) (2 hours)
+
+### Long-term
+8. Set up CI/CD test automation
+9. Add code coverage reporting (target: 80%+)
+10. Implement mutation testing for critical paths
+11. Add contract tests for external integrations
+

+
+## Code Examples
+
+### Example Test: Email Verification Idempotency
+
+```csharp
+[Fact]
+public void VerifyEmail_WhenAlreadyVerified_ShouldBeIdempotent()
+{
+    // Arrange
+    var user = User.CreateLocal(
+        _tenantId,
+        Email.Create("test@example.com"),
+        "hash",
+        FullName.Create("John Doe"));
+    user.VerifyEmail();
+    var firstVerifiedAt = user.EmailVerifiedAt;
+    user.ClearDomainEvents();
+
+    // Act
+    user.VerifyEmail();
+
+    // Assert
+    user.EmailVerifiedAt.Should().Be(firstVerifiedAt);
+    user.DomainEvents.Should().BeEmpty(); // No new event
+}
+```
+
+### Example Test: Invitation Role Validation
+
+```csharp
+[Fact]
+public void Create_WithTenantOwnerRole_ShouldThrowException()
+{
+    // Arrange & Act
+    var act = () => Invitation.Create(
+        _tenantId,
+        "test@example.com",
+        TenantRole.TenantOwner, // Not allowed
+        "tokenHash",
+        _invitedBy);
+
+    // Assert
+    act.Should().Throw<InvalidOperationException>()
+        .WithMessage("*Cannot invite users with role TenantOwner*");
+}
+```
+
+### Example Test: Rate Limit Window Expiration
+
+```csharp
+[Fact]
+public void IsWindowExpired_OutsideWindow_ShouldReturnTrue()
+{
+    // Arrange
+    var rateLimit = EmailRateLimit.Create("test@example.com", _tenantId, "verification");
+    var window = TimeSpan.FromMilliseconds(1);
+
+    // Wait for window to expire
+    System.Threading.Thread.Sleep(10);
+
+    // Act
+    var isExpired = rateLimit.IsWindowExpired(window);
+
+    // Assert
+    isExpired.Should().BeTrue();
+}
+```
