Testing of a complete application environment in a situation that mimics real-world use, such as interacting with a database, using network communications, or interacting with other hardware, applications, or systems if appropriate.Identify the type of testing

End-to-end testing validates the entire application flow in a real-world environment, including interactions with databases, networks, hardware, and other systems. Beta testing is user testing before release. User acceptance testing (UAT) is done by end users to verify requirements. System testing tests the integrated system but not necessarily with real-world external dependencies.
