Automated Architecture Tests Catch Security Gaps Code Review Misses

Structural enforcement through automated tests proves more reliable than manual code review for preventing critical security issues. Even well-executed code reviews can miss architectural violations when reviewers focus on business logic, as demonstrated by a real incident where a missing BelongsToTenant trait caused a multi-tenant data leak. Implementing architecture tests in CI creates a scalable enforcement mechanism that automatically catches violations on every commit, making it an essential complement to human review.
