"Comprehensive Fundamentals of Software Testing: Exploring Core Concepts, Testing Levels, Life Cycles, Manual and Automation Approaches, Functional and Non-Functional Testing Types, Industry Best Practices, and Their Importance in Ensuring High-Quality, Reliable, Secure, and Customer-Centric Software Applications

1. Software Testing Fundamentals Understanding basics, types, levels, and importance of testing

2. What is Software Testing? • Process of evaluating software to ensure it meets requirements. • Identifies defects, ensures quality, reliability, and performance.

3. Importance of Software Testing • Prevents defects from reaching production. • Saves cost and time in the long run. • Ensures customer satisfaction. • Improves product quality.

4. Types of Testing • Manual Testing – Performed by testers without automation. • Automation Testing – Uses tools/scripts to execute tests. • Functional Testing – Verifies business requirements. • Non-Functional Testing – Covers performance, security, usability.

5. SDLC vs STLC • SDLC – Software Development Life Cycle. • STLC – Software Testing Life Cycle. • Both run parallel, ensuring quality at every stage.

6. Testing Levels • Unit Testing – Test smallest code units. • Integration Testing – Verify interactions between modules. • System Testing – Validate complete application. • User Acceptance Testing (UAT) – Ensures product meets user needs.

7. Summary • Software testing is critical for delivering reliable applications. • Covers both functional and non-functional aspects. • Ensures a defect-free, user-friendly product.
