[dongtong]

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.

End-to-end testing involves ensuring that that integrated components of an application function as expected. The entire application is tested in a real-world scenario such as communicating with the database, network, hardware and other applications.

For example, a simplified end-to-end testing of an email application might involve:

• Logging in to the application
• Accessing the inbox
• Opening and closing the mailbox
• Composing, forwarding or replying to email
• Checking the sent items
• Logging out of the application
