🎯 What is S.U.T?
System Under Test
The specific system, component, or software module
that is the target of testing and verification.
Test Target
The actual functionality or system component that needs to be verified and validated.
Isolated Environment
An independent testing environment separated from external dependencies.
Predictable Behavior
Consistent and reproducible results for the same input conditions.
💡 Why is S.U.T Important?
Quality Assurance
Ensures each component functions correctly, guaranteeing overall system quality.
Early Bug Detection
Identifies issues early in development, minimizing the cost of fixes.
Refactoring Safety
Quickly verifies that existing functionality works correctly after code changes.
🏗️ S.U.T Design Principles
Single Responsibility
Each class or function should have only one reason to change.
Dependency Injection
Inject external dependencies to reduce coupling and improve testability.
Interface Segregation
Clients should not depend on interfaces they don't use.
