(Q). What is End to End Testing?
End to End testing is a technique to check whether the behavior of the application flow right from start to finish meets the expectation. It is designed based on the end user’s scenarios to validate the application and the integration of its components. E2E Testing also helps you prevent the risk of whole system collapse due to subsystem failures. The purpose of performing end-to-end testing is to identify system dependencies and to ensure that the data integrity is maintained between various system components and systems.
Why End to End Testing?
Modern software systems are complex and are interconnected with multiple sub-systems.
A sub-system may be different from the current system or may be owned by another organization. If anyone of the sub-systems fails, the whole software system could collapse. This is a major risk and can be avoided by End-to-End testing. End-to-End testing verifies the complete system flow. It helps detect issues with sub-systems and increases confidence in the overall software product.
