Which statement is true regarding device preview in Pega?

Device preview in Pega provides a way for developers to see how their applications will appear on various devices without the need for physical devices. However, while it offers significant convenience and initial visual testing capabilities, it cannot fully replicate all factors that affect user experience on actual devices.

Testing applications on real devices remains crucial because it allows developers to encounter real-world scenarios such as performance costs on different operating systems, screen resolutions, and touch interactions, which may not be accurately reflected in the device preview. For instance, issues like network latency, specific device functionalities, or differences in behavior across browsers cannot be simulated in the preview tool.

The other options imply that device preview can replace manual testing or that it reduces the necessity for actual device testing, which misrepresents its purpose. It serves as a helpful tool in the development process but does not eliminate the need for comprehensive manual testing on various devices to ensure a flawless user experience. Additionally, while device preview is available in Dev Studio, it is not limited to just that environment as it can be accessed during application development.
