Common recording and replaying performance test tool for a client-server environment

摘要

A method, system and computer program product for recording and replaying a program execution in a client-server environment capable of supporting different client-server communication protocols. A common recorder of the exemplary embodiments identifies respective class files and libraries used by a client application to process client actions and data passed in client requests and server responses. The recorder stores class files and data in a replay file and later re-creates server loads and client actions based on the class files, data and client action results in the replay file during a replay of the execution.

1. A computer-implemented method for recording and replaying an execution of a client application in a client-server environment, comprising:
determining, by a common recorder, a type of the client application from a plurality of client application types, wherein the common recorder is configured to identify applications of each of the plurality of application types, the plurality of application types comprising: a Web service application type, a Remote Method Invocation (RMI) application type, a Common Object Request Broker Architecture (CORBA) application type an Enterprise JavaBeans (EJB) application type, and Internet Inter-Orb Protocol (IIOP) application type; identifying, by the common recorder, particular class files used by the client application to process client actions during the execution based on the determined type of the client application, identifying, by the common recorder, data passed in client requests and data returned in server responses to be recorded using contents the identified class files; recording, by the common recorder, the identified class files and the identified data in a replay file; and generating a server load based on the replay file by recreating actions of the client application using the data recorded in the replay file during a replay execution: wherein the common recorder utilizes the particular class files of the client application to interact with the server, wherein the common recorder interfaces with remote interface stubs of a plurality of client applications executed on at least one client, wherein, if the determined application the comprises the Web service application type the identifying the particular class files comprises identifying dynamic proxy class files of the client application; wherein, if the determined application type comprises the Remote Method Invocation (RMI) application type, the identifying the particular class files comprises identifying stub class tiles and skeleton class files of the client application, and wherein, if the determined application type comprises one of the CORBA application type, EJB application type, and IIOP application type the identifying the particular class files comprises identifying “Ties” files of the client application.
