End-to-End Testing checks entire systems from start to finish. It verifies that all components work together correctly. This testing mimics real-world scenarios and user behaviours.
Key Aspects:
1. Tests complete workflows
2. Involves multiple system components
3. Simulates real user environments
4. Identifies integration issues
5. Validates system requirements
Steps in end-to-end testing include defining test scenarios, setting up test environments, preparing test data, executing test cases and analysing results.
