Integration testing in software engineering

1. Integration Testing in Software Engineering Understanding Its Role, Techniques, and Importance Presented by: [Your Name] Date: [Date]

2. What is Integration Testing? - Combines and tests individual units/modules as a group. - Goal: Detect interface defects. - Comes after Unit Testing and before System Testing.

3. Why Integration Testing? - Ensures correct module interaction. - Detects interface defects. - Simulates real-world data flow. - Reduces integration risks.

4. Types of Integration Testing - Big Bang Integration - Top-Down Integration - Bottom-Up Integration - Sandwich/Hybrid Integration

5. Big Bang Integration - Pros: Quick, fewer resources. - Cons: Hard to isolate bugs; late issue detection.

6. Top-Down Integration - Tests top modules first. - Uses stubs for lower modules. - Tests control flow early.

7. Bottom-Up Integration - Tests lower modules first. - Uses drivers for upper modules. - Tests foundational modules.

8. Sandwich Integration - Combines top-down and bottom-up methods. - Balanced and flexible approach.

9. Tools for Integration Testing - JUnit (Java) - NUnit (.NET) - TestNG - Postman (API) - Selenium (UI)

10. Best Practices - Start with unit-tested modules. - Use stubs and drivers well. - Automate where possible. - Document tests. - Perform regression testing.

11. Challenges - Complex module data flow. - Stub/driver maintenance. - 3rd-party API integration. - Synchronization issues.

12. Summary - Validates module interaction. - Choose suitable strategies. - Plan and use tools wisely.
