中文摘要 | 軟體的品質須用精確的量度來判定,因此發展精確的方法與技術來對軟體的各種性質加以預測與評估是必要的。本篇文章的目的就是要發展公式化的軟體可測性量度。軟體可測性是軟體的重要特性之一,它代表一個軟體是否容易被測試的指標。若一個軟體的可測性高,則表示對其進行測試所需要花費的金錢,時間和物力較少,而且,也表示其中所隱含的錯誤較容易被找到。這也就表示了此軟體具有高度的可靠性。我們建議了一種將待測軟體正規化的策略,建議一個軟體被量度之前要先給予正規化,此正規化後的軟體,其可測性的量度精確值將可合理的提高。 |
英文摘要 | It is necessary to define meaningful software metrics and develop precise evaluating methods for prediction and assessment of software systems. The goal of this research is to develop a formulation for a program testability metric model. Testability is a program's property of ease of the testing process to be accomplished. A software with high degree of testability indicates that a selected testing criterion could be achieved with less effort and the existing faults could be revealed more easily during testing process. In this paper we propose a new program normalization strategy that makes the measurements of testability more precise and reasonable. If the program testability metric derived from data flow and control flow analysis could be applied at the beginning of software testing phase, much more effective testing resources allocation and prioritizing could be possible. Such information could also help tester to decide when a testing process could be finished according the criterion selected. |
