Break It, Make It transforms testing from a checkbox into the driving force behind clean architecture, robust code quality, and unwavering team confidence. This guide equips developers to design, write, and maintain automated tests that mirror real-world scenarios at every level?from isolated unit tests to full end-to-end suites.

What You Will Learn

• Craft precise unit tests that isolate business logic and guard against regressions
• Build reliable integration tests for databases, APIs, and external services
• Automate end-to-end workflows that catch system-wide failures before they reach production
• Adopt the Red?Green?Refactor cycle and the smallest-failing-test mindset to drive design
• Apply SOLID principles and Law of Demeter for cleaner, more testable code
• Leverage dependency injection, mocking, stubbing, and spying techniques with NUnit and Moq
• Scale your test suite as your codebase grows, keeping tests fast, dependable, and easy to maintain
