A Micro-Kernel Test Engine for Automatic Test System

Abstract

Abstract-In traditional automatic test solutions, a testengine usually encompasses all functions in its kernel, including compiling test program, generating test event chain, scheduling test process and executing test events. This makes the engine tightly coupled with test language and the system under test, so that it is difficult to maintain, optimize and extend the test engine. In order to solve these problems, a micro-kernel test engine is designed and implemented based on the service oriented architecture. This microkernel approach decouples function modules to make the test engine kernel independent of the system under test and the test language. This also makes the test engine more modularized, so that the debugging process and maintenance work of the engine can be much easier. With new compiling component and test adapters, the engine kernel can be extended for new test methods or reused in new test applications. The application example and extensibility analysis discussed in section 6 show the feasibility of this micro-kernel test engine.Index Terms-automatic test system, test engine, microkernel, service oriented architecture

An Approach for Domain Reduction with Data Dependence in Mutation Testing

“…Reference [20] proposes a micro-kernel engine to optimize the automatic test system and reference [21] proposes a software reliability test method based on Markov usage model. Many methods use the genetic algorithm to optimize the TDG [22,23,24].…”

Multi-operative USB HD: An All-In-One Solution to IT Supports and Forensic Experts

“…Since this usb HD already has a platform to add and remove , a Linux distribution, which is helpful for computer security professionals. Besides this, sometimes, customized and optimized kernels also need to be tested [11]- [13] and those can be added to this usb HD as well. The reminder of this paper is organized as follows.…”
