Integration Testing verifies that combined components work correctly together. It follows unit testing and precedes system testing.
Key Aspects:
- Tests component interactions
- Verifies data flow between modules
- Checks interface compatibility
- Identifies integration-related defects
- Ensures combined functionality
Types of Integration Testing:
- Big bang integration testing
- Incremental integration testing
- Top-down integration testing
- Bottom-up integration testing
Benefits:
- Detects interface defects
- Verifies component compatibility
- Ensures proper data flow
- Identifies timing and performance issues
- Improves overall system reliability
Integration testing is crucial for complex systems with multiple interacting components.
