There's a new eValid movie you might want to review that shows eValid operating in "test unification" mode. By "test unification" we mean the ability to have one test script server multiple purposes, e.g. for tuning properties of a page (how fast parts of it download), or confirming availabilty through monitoring, verifying non-regression (nothing's changed when nothing is supposed to have changed), or for inclusion in a multi-user server loading experiment.
The movie illustrates eValid's ability to do page tuning, functional testing, and server loading, all from the same base. The new 3WAY Movie [shows in a new window, duration 05:39] illustrates how simple this can be.
