# What is Testing?

- Testing evaluates software quality and risk
- Testing provides information, not absolute proof
- Quality includes functional and non-functional attributes

# Quality Attributes (ISO 25010)

- Key attributes include performance, security, maintainability
- Functional correctness is only one part of quality
- Test strategy should map to target attributes

# Testing Principles (ISTQB-oriented)

- Early testing saves cost and rework
- Defects cluster in a small number of modules
- Tests wear out and need regular review

# Static vs Dynamic Testing

- Static: reviews, walkthroughs, linters, SAST
- Dynamic: executing software with test cases
- Both are complementary and should coexist

# Test Levels and Types

- Levels: component, integration, system, acceptance
- Types: functional, non-functional, structural
- Select level/type based on risk and feedback speed
