Bài giảng Công nghệ phần mềm - Kiểm định và tiến hóa phần mềm

The rapid advancement and increasing reliance on software systems in all aspects of modern life underscore the critical importance of delivering high-quality, reliable, and secure software. In this context, "kiểm định phần mềm" (software testing) and "tiến hóa phần mềm" (software evolution) emerge as indispensable disciplines. Effective testing ensures that software functions as intended, meets user requirements, and is free from critical defects, thereby mitigating risks and enhancing user satisfaction. Concurrently, understanding software evolution is vital for managing the long-term viability and adaptability of systems in dynamic environments. This document provides an overview of fundamental concepts and methodologies associated with these crucial processes.

This academic overview delves into the core principles of "kiểm thử phần mềm" (software testing) and its broader context within "tiến hóa phần mềm" (software evolution). It begins by defining software testing as a systematic process aimed at demonstrating that a program performs as expected and, crucially, identifying defects before deployment. The document distinguishes between the primary objectives of testing: "validation testing", which confirms that software meets specified requirements from both developer and customer perspectives, and "defect testing", which pinpoints instances of incorrect, unexpected, or non-compliant software behavior. A structured model for the software testing process is presented, outlining key stages from designing test cases and preparing test data to executing programs and comparing results. Furthermore, the material explores various established "phương pháp kiểm thử" (testing methods), including "black-box testing", which focuses solely on input/output behavior based on requirements; "white-box testing", which examines the internal structure and logic of the code (e.g., covering lines and branches); and "gray-box testing", a hybrid approach combining elements of both. The discussion highlights that while testing can reveal the presence of errors, it cannot definitively prove their absence. Finally, by integrating these testing concepts into the broader lifecycle of software, the document implicitly emphasizes their role in enabling "bảo trì phần mềm" (software maintenance) and continuous improvement, which are integral aspects of software evolution.
