Have you ever used or run simulation platforms in your practice?

Yes, in QA practice and test automation, simulation platforms (simulators, emulators) are often used. They allow reproducing the behavior of real systems or devices when access to them is limited or expensive.

For example, when testing a mobile application, an Android or iOS emulator can be used to check the application's functionality without a physical device. In other cases, simulators can mimic the operation of servers, network devices, or external services.

This helps to:

• Automate tests in a controlled environment.
• Test scenarios that are difficult to reproduce on real devices.
• Reduce costs for equipment and infrastructure.
