End-to-End Software Testing

End-to-end testing, also known as E2E testing, is a methodology used for ensuring that applications behave as expected and that the flow of data is maintained for all kinds of user tasks and processes.

This type of testing approach starts from the end user’s perspective and simulates a real-world scenario.

Purpose of the End-to-End testing

End-to-end testing makes it simpler to catch problems before releasing the software to end users.

End To End Testing verifies complete system flow and increases confidence by detecting issues and increasing Test Coverage of subsystems.

Modern software systems are complex and interconnected with multiple subsystems that may differ from current systems. The whole system can collapse by failure of any subsystem that is major risk which can be avoided by End-to-End testing.
