How can network emulators help in testing applications before deployment?
Network emulators can help test applications before deployment by creating a safe copy of a real network. They let developers see how an application works under different network conditions like slow speed, delays, or lost data. This helps find problems that might happen when real users use the app. For example, if a video app freezes on a slow network, emulators can show this before release. Developers can also test security, stability, and performance without affecting real users. Using emulators saves time and money because fixing problems later is harder. They can repeat tests many times with different settings. Overall, network emulators make sure applications work well in many situations and help developers deliver better and more reliable software to users before it goes live.
