Stress test Examples

Using modern design techniques and formal technical reviews can reduce the initial errors that exist in the code, but errors always exist, and if the developer cannot find the error, the customer will find them. More and more software organizations realize that software testing is one of the important elements of software quality assurance, many software development organizations will 30%-40% and even more project resources used in testing, software testing technology and software testing strategy has been highly valued and widely used.

This article does not want to carry on the thorough theory analysis to the software test technology and the software Test strategy, but enumerates one in the software system test stage to undertake the pressure test example, hoped can through this example and carries on the software test related work the friend to communicate.

First of all, introduce the project background of the software, the software is a typical three-tier C/s architecture of MIS system (client/Application server/Database tube), the middle tier is the business logic layer, the application server handles all the business logic, but the application server itself does not provide load balancing capacity, Instead, the Orb (object request agent) software provided by development tools is used to ensure load balancing among multiple application servers. The purpose of this test is to perform a stress test on a single application server to find out the maximum number of clients that a single application server can support. The test pressure estimate is based on the assumption that in the actual loop, the user only has one application server enabled for all business processing. The method is to test the operation of the application server according to the 1~10 times of the normal business pressure estimation value.

The detailed plan for the stress test is as follows:

Stress test Plan

1. Name of test plan

Hebei Province Police Traffic management information system pressure test plan.

2, test content

2.1 Background

The stress test in this test is to simulate the actual application of the software and hardware environment and user process of the system load, long time to run the test software to test the reliability of the system, but also to test the response time of the system tested.

User's actual use environment:

◇ Microsoft Cluster made up of two IBM XSeries250 PC servers;

◇ The database management system adopts Oracle8.1.6;

◇ the Application server program and the database management system run at the same time on the Microsoft Cluster.

◇ 200 users use client software for business processing, the total number of business processed by software each year is: 1.5 million business/year.

2.2 Test items

Application server's stress test;

2.3 Features that are not tested

◇ the internal function of the system's client application;

◇ The effect of data quantity in database on program performance.
