摘要
随着信息技术的快速发展，软件系统在各行业中的应用日益广泛，其复杂性和规模也持续增加，这对软件质量保证与测试策略提出了更高要求。本研究以大型软件项目为背景，探讨了软件质量保证与测试策略的有效实施方法及其对项目成功的关键作用。研究旨在通过系统化的分析和实践验证，提出一种适用于大型项目的质量保证框架及多层次测试策略，从而提升软件开发效率与产品质量。研究采用理论分析与实证研究相结合的方法，首先梳理了现有软件质量模型与测试方法的优缺点，随后基于某实际大型软件项目的数据，设计并实施了一套涵盖需求分析、设计、编码、测试等阶段的全流程质量保证方案。结果表明，该方案显著降低了缺陷密度，缩短了测试周期，并提高了用户满意度。本研究的创新点在于将动态风险评估机制融入质量保证流程，实现了测试资源的优化配置，同时提出了基于场景驱动的测试优先级排序方法，有效提升了关键功能的覆盖度。总体而言，本研究不仅为大型软件项目的质量管理提供了实践指导，还为相关领域的理论发展做出了贡献。

Abstract
With the rapid development of information technology, the application of software systems in various industries has become increasingly widespread, and their complexity and scale have continued to grow. This trend imposes higher demands on software quality assurance and testing strategies. This study, set against the backdrop of large-scale software projects, investigates the effective implementation methods of software quality assurance and testing strategies and their critical role in project success. Aiming to enhance software development efficiency and product quality, the research proposes a quality assurance fr amework and a multi-level testing strategy suitable for large-scale projects through systematic analysis and practical validation. By combining theoretical analysis with empirical research, the study first evaluates the advantages and disadvantages of existing software quality models and testing methods. Subsequently, based on data from an actual large-scale software project, a comprehensive quality assurance scheme covering requirement analysis, design, coding, and testing phases is designed and implemented. The results indicate that this scheme significantly reduces defect density, shortens the testing cycle, and improves user satisfaction. The innovation of this study lies in integrating a dynamic risk assessment mechanism into the quality assurance process, achieving optimized allocation of testing resources, and proposing a scenario-driven test priority ranking method, which effectively enhances the coverage of critical functions. Overall, this study not only provides practical guidance for quality management in large-scale software projects but also contributes to the theoretical development of related fields.
