Abstract:

Software testability analysis can help designers to develop a program more testable and reduce the difficulty and cost of software testing. A method based on a framework is brought forward to analyze the testability of different programs and provide all kinds of testability information. The framework consists of a metric of testability, metrics of testable characteristics, metrics of testability factors and their relationships. Firstly, some metrics of testability factors are selected from the framework according to the features and testing conditions of different software. Then, testability factors which impact one testable characteristic are analyzed to calculate the testable characteristic through a fuzzy calculation model. Finally, all testable characteristics are considered together to measure the software testability. An application indicates the proposed method is feasible and helpful to the software development.
