When should I use ApP (Emulated Browser) to record a test script?
Many Web pages and applications can be monitored in both the Real Browser (TxP) and Emulated Browser (ApP) services – with the only difference being in the fidelity of the user experience reported. Where site or application availability is the primary concern, or where the performance of a backend application (for example a login process) in which the downloading of all items on a page is not relevant then the Emulated Service (ApP) is suitable for monitoring. The inherent strengths of an emulated browser include the rich programmability (using JavaScript), emulation of multiple browsers, and ability to exclude any Web content. Also, since cost of running an emulated measurement is cheaper than running one on a real browser, the Application Perspective service has a significantly reduced price.
