Abstract
Architectural design is a crucial issue in software engineering. It makes testing more effective as it contribute to carry out the testing in an early stage of the software development. To improve software testability, the software architect should consider different testability metrics while building the software architecture. The main objective of this research is to conduct an early assessment of the software architecture for the purpose of its improvement in order to make the testing process more effective. In this paper, an evaluation model to assess software architecture (Architecture Design Testability Evaluation Model (ADTEM)) is presented. ADTEM is based on two different testability metrics: cohesion and coupling. ADTEM consists of two phases: software architecture evaluation phase, and component evaluation phase. In each phase, a fuzzy inference system is used to perform the evaluation process based on cohesion and coupling testing metrics. The model is validated by using a case study: Elders Monitoring System. The experimental results show that ADTEM is efficient and gave a considerable improvement to the software testability process.

Many studies have been conducted to address software testing to reduce software testing efforts by handling software testability at early stages in the software development life cycle (SDLC) [1] [3]-[6]. Software Testability (ST) is the quality attribute about the easiness degree to which system’s defects can be detected at testing phase [3]. The better the testability of particular software, the lower the testing effort required in testing phase. The earlier the testability is considered, the lower the cost of testing phase. ST should be considered at the early phases of software development life cycle (SDLC), in the software architecture (SA) [2] [3]
