Testing today's complex, hybrid applications is getting harder and harder. One reason is that "Application" Under Test is now really a system of many applications. In order to really emulate the business processes conducted by users, we sometimes need to interface through multiple technologies. In the world of performance testing, that means we may be using one application based on a legacy interface (say, 3270) to produce some piece of information we need, and then using that piece of information as an input to a second application (say, a web-based application).
This video demonstrates an easy, effective way to pass information between performance tests of the same or different protocols through Rational Performance Tester's graphical interface with no coding required.
