Software Quality Assurance Practice Exam

What is an advantage of using an emulator in device testing?

1. It can test the responsiveness of an application

2. It can identify device-specific bugs

3. It is cost-effective

4. It can test the code base once

The correct answer is: It is cost-effective

Using an emulator in device testing offers a range of benefits, and being cost-effective is one of the primary advantages. Emulators allow developers and testers to simulate different devices and operating systems without the need to purchase or maintain physical devices, which can be expensive. This cost efficiency is significant, especially for small teams or projects with limited budgets, as they can test applications on multiple configurations simultaneously without incurring the expenses associated with acquiring every device. Emulators can replicate various hardware configurations and software environments, providing a robust platform for testing applications quickly. This is particularly beneficial during the initial development phases when budget constraints may limit access to real devices. While emulators have their limitations, such as potentially missing out on hardware-specific behaviors or issues, their cost-effectiveness makes them a valuable tool in the software quality assurance process.
