Abstract Recent IEEE and Department of Defense (DoD) initiatives to standardize automatic test equipment (ATE) architectures are providing unique opportunities to improve the development of test systems. The purpose of A Broad Based Environment for Test (ABBET) initiative is to provide the next generation in ATE and test program set (TPS) development through the standardization of test services and test development tools. The Artificial Intelligence and Expert System Tie to Automatic Test Equipment (AI-ESTATE) initiative will provide architectures for standardizing the test services of reasoning systems and provide guidance for test strategy services supporting the ABBET architecture. In this paper we focus on one of the standards proposed under AI-ESTATE for developing diagnostic models that proposes models for the object-oriented design of fault trees and enhanced diagnostic inference models. We will also discuss the applicability of the AI-ESTATE P1232.1 Data and Knowledge Specification standard to object-oriented testing, and we will propose an architecture for combining ABBET and AI-ESTATE into a comprehensive ATE system. Introduction Recent initiatives by the IEEE and the DoD that will standardize automatic tes
