Research on the TPS development based on SOA

Open-architecture test systems were supposed to simplify TPS development, which is an effective way to preserve existing TPS investment from legacy ATE to new test systems. However, when developing test applications, we find it difficult to get perfect performance because of the formality of the interface protocols and object-levels of granularity. Objects are fine grained and not sufficiently abstracted away from the implementation design. In this paper, service oriented architecture (SOA) is introduced and adopted to solve this challenge. The focus of this paper is on consideration for service-oriented test software architecture, within which, test applications, user interface, diagnostic data and other assets are viewed as services. Each of these services can be mixed and matched to create new, flexible test software. By encapsulating a test application behind capability-based interfaces, these services can be reused and create new value from existing TPSs.
