Research Of Automation Test System For Modems Based On ALM

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.
