Comprehensive System Quality Assurance Practices and Team Development in Rapid Iteration Environments

In this session, Zhang Qi, head of the POP platform testing and quality management team at JD.com, shares his extensive experience in ensuring system quality for the POP e‑commerce business and the 7FRESH offline store, focusing on efficient full‑cycle quality assurance, big‑data‑enabled testing, and team development.

Full‑cycle quality assurance is emphasized, with quality activities embedded throughout the software lifecycle: early involvement in requirement reviews, design and test‑case reviews, static code analysis with Sonar, layered testing (UI, API, data), automation, security testing, pre‑release checklists, product trial mechanisms, baseline performance testing, and post‑release online verification, automated regression, and stability monitoring.

Tooling and efficiency are highlighted, describing a suite of tools and platforms that support testing depth, breadth, and efficiency, organized into foundational tools, operations management tools, process improvement tools, productivity‑enhancing practices, and quality platforms.

The article outlines three key roles of testers: quality guardian (ensuring overall system quality and user experience), process promoter (building and driving efficient workflows), and quality culture evangelist (spreading quality mindset across the organization).

Big‑data techniques are applied to testing by collecting real‑world API data, clustering it via machine learning, validating data relevance over time, recommending high‑coverage test cases, and enabling semi‑automated testing triggered by code merges, thereby significantly improving test efficiency.

Team development is driven by regular knowledge‑sharing sessions, a “soft‑hard” skill balance, personal growth goals, and a culture of both technical and communication skill enhancement, fostering a high‑execution, innovative, and collaborative team.

Achievements include publishing JD's first testing and quality management book, multiple internal and external talks at industry conferences, and organizing the first JD quality testing forum, demonstrating the team's influence both within and outside the company.

The speaker concludes by thanking the organizers, leadership, and teammates, expressing pride in the team's accomplishments and wishing continued success for the “牛人说” column.
