The web load test apparatus includes a virtual web client generation section to generate virtual web clients each of which transmits a request message to a web server and receives a response message according to a scenario; a memory section to store synchronous point that specifies an order in the scenario of the response message, which is a synchronous point among the response messages, into a storage; a waiting section to interrupt the accesses by the clients until a time when all the clients receive the response messages whose orders are indicated by the synchronous point; a resumption section to resume the accesses when all the clients receive the response messages whose orders are indicated by the synchronous point; and a rewrite section to replace the synchronous point stored in the storage with synchronous point that specifies another response message.
