Leveraging ChatGPT to Transform Software Development

Since the industrial era, humanity has progressed through traditional industry, the information age, the internet and mobile internet age, and now the artificial intelligence and large‑model era. In this AI era, large language models cannot fully replace humans but can effectively assist them. For software engineers, models such as ChatGPT can help with requirement analysis, design, code development, unit‑test design, end‑to‑end test design, performance and security testing, as well as performance‑test result analysis and module‑risk adjustment. Because of hallucination issues and training‑data interference, model outputs are not always accurate, so human reviewers must verify results, ask follow‑up questions, or refine them based on personal experience. Using large models for software testing thus follows a PDCA iterative improvement process that requires cooperation between “natural people” and “robots”.

The book "Playing with ChatGPT for Software Development" uses ChatGPT as an example to show how prompt engineering can help developers complete tasks in requirement gathering, design, coding, testing, and operations. Since the book’s publication, many domestic large‑model tools have emerged, such as DeepSeek, Alibaba Qianwen, Tencent Yuanbao, and ByteDance Doubao, along with more advanced intelligent agents—GUI‑type agents for non‑IT users and coding agents for IT professionals. However, the core concepts of effective human‑robot communication and the analysis and refinement of model‑generated results remain timeless. Readers are encouraged to look beyond surface content and explore the underlying principles of human‑machine dialogue.

The article concludes by likening a large language model to a freshly graduated top student—well‑grounded in knowledge but lacking real‑world project experience. Users must teach the model how to work on projects. If the reader is also a recent graduate, they should first solidify IT fundamentals and gain project experience before applying the book’s content; after accumulating experience, they can guide the model together toward progress.
