How JD.com Prepares Its Systems for 11.11: Stress Tests, Forcebot Evolution, and Quality Controls

Full‑Chain Stress Test for 11.11

On October 17, JD.com conducted its second end‑to‑end pressure‑test rehearsal, covering the four main traffic entry points—APP, PC, WeChat, and mobile web—from homepage and search to cart, checkout, and payment. The test confirmed that JD's systems remain rock‑solid ahead of the final 11.11 showdown.

Leadership Emphasizes "Respect" (敬畏)

Wang Jinping, head of Engineering Efficiency in the Retail Technology and Data Platform, highlighted three forms of respect—respect for preparation, for contingency plans, and for traffic volume—stressing that every technical team must prioritize 11.11 readiness and allocate maximum effort.

Forcebot’s Evolution as the Core Testing Tool

Forcebot, JD’s primary tool for full‑chain rehearsals, received a major upgrade: a new traffic‑recording and replay capability. Engineer Ma Xin explained that this reduces developers’ reliance on manual data preparation, avoids resource and security risks of in‑app traffic capture, and will become a routine capacity‑assessment method.

Meticulous Organization of the Rehearsal

Han Wei, leading the large‑scale rehearsal, broke down tasks to the individual level, set precise timelines, and continuously verified scenarios, data, and environments with relevant teams. His detailed coordination ensured the four‑week rehearsal proceeded smoothly.

Quality‑First Approach: "Quality Month" and Ten Safeguards

To prevent recurring issues and online incidents, the Engineering Efficiency team introduced a "Quality Month" concept, deploying ten concrete measures: unified issue reporting, incident‑review follow‑up, case studies and process training, process inspections, release control, middleware quality guarantees, third‑party SDK audits, autonomous regression checks, dedicated monitoring personnel, and close collaboration with business partners.

Broad Knowledge Sharing Across JD

The quality team delivered eight training sessions covering typical incident cases and critical processes to over 1,000 engineers across JD’s North‑China, Yizhuang, and Chengdu workplaces. They also coordinated with the Architecture and Big Data departments to compile middleware readiness guidelines, extending the training to JD Retail’s subsidiaries in Indonesia and Thailand.

With these preparations, JD aims to keep its technology platform stable and resilient throughout the upcoming 11.11 peak.
