基于ALM的MODEM自动化测试系统的研究
|
摘要
调制解调器(MODEM)作为家庭网关中重要的通信设备,其软件质量直接影响到所在网络环境的传输性能。对MODEM产品进行软件测试是保证其各方面达到开发及用户的要求的必要途径。目前,调制解调器的测试大部分采用测试人员手动执行的方法,存在着测试重复率高、效率低、干扰因素多等不足。随着自动化测试技术的不断发展,研究如何改进测试方法、实现对MODEM测试的自动化具有较大的实用价值。
本文对MODEM的基本理论知识进行了概括论述,对MODEM工作的接入网络环境进行了深入探讨,并在系统地介绍常用测试方法的基础上,对MODEM的LIT集成测试展开讨论,提出一种基于ALM工具的LIT自动化测试系统,,目的是在保证测试准确度的前提下提高对MODEM测试的效率。
本文先提出LIT自动化测试系统的整体设计思路,即通过采用BLINKY和SWITCHY等设备联合控制的方法,来实现一台测试机同时控制16个MODEM自动地进行测试的目的。本文对LIT测试用例的设计、测试环境的搭建、自动控制的实现方法、测试的网络环境等进行了详细地设计和阐述。随后,本文对ALM自动化测试工具进行了分析,并设计出适用于ALM的基于TCL的LIT自动化测试脚本,最后对整个LIT测试系统的测试实现过程进行了演示说明,结果表明本文研究的LIT测试系统是合理的、可行的。
As an important communication device in the home gateway, MODEM's software quality will directly affect the transmission performance of network environment in which it is used. Software testing is a necessary way to ensure that MODEM's quality can achieve the requirements of the development and the needs of users. At present, test on MODEM mostly adopts manual implementation method, which has some disadvantages, such as high repetition rate, low efficiency, and other interference factors. With the continuous development of automation technology, research on how to improve the test method and realize the automation of MODEM test has great practical value.
In this paper, the basic theory of MODEM was introduced, the access network environment in which MODEM works was thoroughly discussed, and common test methods in product development were outlined. And on the basis, this paper focused on the discussion of MODEM LIT integration test, and proposed an automation test system based on ALM tools for MODEM LIT test to improve the efficiency of MODEM test on the premise of test accuracy.
Firstly, this paper put forward the overall design idea of LIT automation test system, that is, this system used combined control method with the BLINKY and SWITCHY equipments to achieve the purpose of a test machine controlling16MODEMs automatically. The design of LIT test cases, set up of LIT test environment, method of automatic control in LIT, and the backbone of LIT test network were studied and described in detail. Then, this paper analyzed the ALM automation test tool and designed LIT test scripts matched with ALM with TCL. Finally, the implementation process of the whole system was demonstrated in this paper, and the results showed that the LIT automation test system discussed and studied for MODEM was reasonable and feasible.
