Sometimes there is a need to execute another test (sub-test) from a Rapise test. Doing so with Global.DoInvokeTest or RVL.DoPlayTest will run the sub-test in the context of the calling test, it will reuse same browser profile or mobile profile, it will use same loaded libraries. Such mode of execution may produce different results compared with running the sub-test standalone. To run the sub-test in isolated mode use Global.DoInvokeTestParallel and RVL.DoPlayTestParallel.
