There's nothing new about automating workloads for testing in remoting environments. But you do need to do it - and the more realistic you can make the workload, the more accurate your test results will be.
That's why the REX Analytics framework comes with a library of workloads to use in your tests.
REX combines these workloads to create different kinds of user personas. Since not everyone works the same way you can use a variety of personas in your testing to derive more realistic results.
