In E2E testing, tests are executed in an environment that simulates a ________ user environment.

In End-to-End (E2E) testing, tests are executed in an environment that simulates a real user environment. This means the tests mimic the actions and interactions of real users with the application, helping ensure that the application works as expected in a production-like setting. While controlled and isolated environments may be used in testing, they are not the primary focus of E2E testing. Production environments are typically not used for testing to avoid risks to the live system.
