A DSL based pressure test platform for broadband trunking system

Traditional manual pressure test requires a lot of testers and clients and has difficulty in reproducing errors. Automatic test methods are also used in the test and simulation of trunking system. However, the protocol of trunking system is stateful, some testing methods like packet playback are not suitable for the test of trunking system. This paper presents a design of Domain Specific Language based test platform for broadband trunking system, which embeds a well-designed and easy-writing test script which describes the highly parallel testing scenarios, a controller which dispatches test tasks and several simulators which ensure the test cases can be executed with low latency. With the help of the test script, testers can write test cases easily without knowing much details about the concurrency. The controller interprets the test script, generates test tasks which are then sent to the simulators, gathers result from simulators to makes the test report. With the event-driven asynchronous task engine, high concurrent test cases can be executed in an efficient way.
