Web load test method and web load test program

Abstract

The web load test method makes a computer function as virtual web client generation means for generating a plurality of virtual web clients each of which transmits a request message to the web server device and receives a response message according to a scenario; memory means for storing synchronous point information that specifies an order in the scenario of the response message, which should be a synchronous point among the response messages, into storage; waiting means for interrupting the accesses by the clients until the time when all the clients receive the response messages whose orders are indicated by the synchronous point information; resumption means for resuming the accesses when all the clients receive the response messages whose orders are indicated by the synchronous point information; and rewrite means for replacing the synchronous point information stored in the storage with synchronous point information that specifies another response message.
