Static Testing in Software Engineering - Reducing Defect Leakage

Aindrila Ghorai

Abstract: This research endeavor delves into the pivotal role of static testing methodologies in mitigating defect leakage within the software development lifecycle. Defect leakage, a phenomenon characterized by the stealthy propagation of undetected defects throughout subsequent phases of development, poses significant risks to project timelines, budgets, and overall product quality. Analogous to the compounding principles fundamental to the Time Value of Money in finance, defect leakage exhibits a compounding effect within software development, whereby defects introduced early in the lifecycle escalate in severity and costliness as they progress unchecked, ultimately culminating in potentially catastrophic consequences upon detection in production environments. At the core of this study lies the critical examination of requirements, which serve as the foundational building blocks of software products. Requirements, when articulated with precision and clarity in alignment with business objectives, provide the essential framework for successful project execution. However, the presence of incomplete or ambiguous terminologies within requirements documentation can precipitate significant challenges, emerging as a primary source of project complexity and risk. These inadequacies within requirements formulation not only impede effective software development but also exacerbate the likelihood of defect leakage and subsequent project disruptions.
