Selected Answer: D
End-to-end testing is a methodology used to test whether the flow of an application is performing as designed from start to finish. The purpose of carrying out end-to-end tests is to identify system dependencies and to ensure that the right information is passed between various system components and systems. The entire application is tested in a real-world scenario such as communicating with the database, network, hardware, and other applications. Therefore, it closely simulates real-world usage of the application. Other options are benefits of different types of testing, not specifically end-to-end testing.

Selected Answer: B
End-to-end tests use an example scenario, do not necessarily follow complex real world. Unit tests are component wise, end-to-end tests go over components.
