Abstract: Disclosed is a scenario generation program that is used to generate a scenario given to a plurality of virtual web clients each of which applies access load to a web server device of a test target. According to the program, a computer stores some first request messages transmitted to a web server device and some second request messages transmitted to the web server device based on the same operation. The computer extracts the differences between the request parameters in the first and second request messages in the same order of the same operation. If page data of a response message includes the extracted request parameters, rewriting-item information is generated corresponding to the request parameter and is incorporated into the scenario. The computer replace the parameter shown by the rewriting-item information whenever the computer executes the scenario.

Abstract: 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.

Abstract: A load simulator is used to apply access load on a web server device as a test target using a plurality of virtual web clients each of which transmits a request message and receives a response message in order according to a given scenario. The load simulator makes a computer function as search means for searching page data of a response message for predetermined character strings when a virtual web client receives the response message from the web server device through a communication device, source modifying means for overwriting the predetermined character string searched by the search means by replacing characters of a part of the string to disable a function provided by the original character string, and output means for passing the page data that is overwritten by the source modifying means to the viewer.

Abstract: A web load test program to display information about responses acquired by applying access load on a web server device as a test target is provided. The program generates a plurality of virtual web clients each of which transmits a request message to the web server device and receives a response message from the web server device in order according to a given scenario. The program stores a log information record containing an ID of the virtual web client that receives a response message and order information that shows an order of the request in the scenario corresponding to the response message into storage whenever the virtual web client receives a response message from the web server device. The program sorts the log information records that are linked with the respective response messages according to a predetermined sort condition and displays the sorted log information records onto a display.
