Design And Implementation Of Testing For Digital Double Loop Center In Mds3400Switch System

The Command and Control System (MDS3400) of JiaXunFeiHong (JXFH) Company, whose open architecture and a special process meet the needs of Command and Control of various industries, collects applications of voice and data business as a whole. There are functions of MDS3400which are selected call, group call, and current broadcast, forced inserting, forced demolition, forced making, clustering and other scheduling features. And it supports for multi-user, multi-level setting. It meets the group of users for network in different fields for its design of openness, compatibility and high-reliability. And it provides customers with safe and reliable system for its flexible and integrated access, personalized formulation and advanced maintenance, makes command and dispatch more convenient and efficient. Currently, the system has been successfully applied in the petroleum, petrochemical, steel, coal, military, public security, railway, subway and other industries.Firstly, synthesis and analysis of the test method, then you need to be tested MDS3400dual-center operations were introduced, and its collation and analysis of the demand for and obtained the corresponding function modules, and then one by one analysis of these functional modules obtained its sub-function modules, and finally arrive at the testing requirements of the corresponding function. The demand for functional testing of the two-center operations as a whole, the black-box testing approach to design test cases, test principle is to achieve full coverage of the demand, design methods include:Scene law, equivalence partitioning method, boundary value analysis, error guessing method. Test case design is complete, immediately set up a test environment, then testers cross-execution of test cases, and test results summarized summary, the final analysis of test data to complete the test report. Finally, according to the test execution conclusions drawn test results, to provide users with the quality of the product in accordance with, but also for the quality of the product management department provides the basis and recommendations.This article is of internship during the software testing center in the Beijing University of Posts and Telecommunications, to test the good news MDS3400switch Command and Control System, written summary of test data and experience. Of work in the test project for functional testing (black box testing), a needs analysis for the functional modules of the system, in order to decompose the functional testing requirements, then design the corresponding test cases, and then execute the test cases. Final test results of the implementation and analysis of test results. MDS3400two-center case three-dimensional display of a black-box testing in embedded systems, provides a reference model for testing related products, and also test for the MDS3400 the business has opened up a new test ideas.
