Abstract
The interfaces and data structure of virtual testing applications are dynamically generated according to VFL (Virtual Testing Framework Language) files, which result in changes to the source codes of data recording and playback systems. Thus, the structure and key technologies of existing recording and playback systems are not suitable for the recording and playback systems of the virtual test frame. This paper discusses the architecture of data recording and playback systems, whose features are dynamically generated and centralized according to recording policy. The architecture consists of data recording and playback tools, and their builder. The recorded replay data format and key algorithms in the architecture were investigated. Data recording and playback systems were then implemented; test results indicate that the generated data recording and playback tool can correctly record and playback data for different virtual test applications.
