以測試案例管制程序改善IID持續測試風險之研究

A Study of Test Case Management Procedure for the Risk Improvement of IID Continuous Testing

敏捷開發方法採取反覆與漸增開發（IID）製程，可以有效降低需求變更與環境變動的衝擊，是目前改善軟體開發風險的實用方法。IID製程反覆開發完成可運作版本，立即進行測試與評估，可及早發現製程問題與品質缺失，減少缺失的遞延與擴大。不過，IID 每次反覆作業都須進行繁複測試，持續的測試工作不僅耗時且花費過多資源，其中廻歸測試是為了避免各種變動形成的廻歸錯誤，卻經常因資源有限而被忽視，成為IID製程必須克服的重大挑戰。妥善管理與利用既存的測試案例，可以有效提高自動化測試效益，具體彌補持續測試的資源困境。本文探討持續測試主要步驟、衝擊與可採取的測試方式，剖析測試案例的重要性與可再用性，進而以測試案例關鍵品質特性為基礎，提出一套測試案例可再用品質量測（TCRQM）模式，且以可再用測試案例為基礎規劃一套測試案例管制程序（TCMP），強化 IID 自動化測試能力，適時降低持續測試須投入的時間與資源，有效的降低 IID 軟體專案的開發風險。

Agile development model to take Iterative and Incremental Development (IID) process, can effectively reduce the impact of requirement and environmental changes. IID is a practical method to reduce the risk of software development. The IID process develops in an iterative manner to identify process problems and quality defects, and effectively reduce defects expansion. However, IID need to be tested for each iteration, and continuous testing (CT) is not only time consuming and need more resources. In order to avoid the regression faults and quality defects of new software version, regression testing is a critical and necessary task. Lack of automated testing, regression testing often leads to product quality defects in IID process. Automated testing can effectively compensate for the lack of resources and personnel of IID regression testing. Effective management and use the existed test cases is the necessary conditions for improve test automation. In this paper, the IID process and CT are discussed, and the importance and reusability of the test cases are analyzed. Applied quality measurement mode to strengthen the test case reuse quality. And, based on the quality factors of test cases, the Test Case Reusable Quality Measurement (TCRQM) model is proposed. Applying the reusable test cases, the paper designs a test case management procedure for assisting the IID to control regression test cases, effectively reducing the time required to and human resources in regression testing. IID process with a high automated testing capabilities to improve product interaction ability and developers’ morale, and effectively reduce the IID software project development risks.
