Abstract

According to one embodiment, the invention comprise a Translation Tool, that translates messages in a client/server system into a form compatible with a Load Testing Tool, which are used to create a script for the Load Testing Tool. The Load Testing Tool utilizes the script created with the messages converted by the Translation Tool to generate emulated messages to test and evaluate the performance of the client/server system. The Translation Tool (possibly the same as the first translator) translates the messages generated by the Load Testing Tool into a form compatible by the client/server system.
