This article details the challenges, planning, and step‑by‑step execution of creating an isolated regression environment for a large micro‑service platform, covering quantifiable goals, solution evaluation, infrastructure refactoring, data migration, deployment results, and future improvements.
To overcome inefficient, unstable offline testing, Yanxuan built an isolated regression environment by provisioning dual cloud‑inside/outside clusters, refactoring infrastructure, deploying roughly 180 core B‑side services, and constructing migration data, achieving over 90 % cloud‑native coverage and enabling stable pre‑release verification with future expansion plans.
This article documents the step‑by‑step practices of a six‑person test‑environment availability team that unified middleware, streamlined deployment pipelines, piloted business usage, introduced monitoring and recovery mechanisms, and created a comprehensive SIT environment handbook to improve integration testing stability and operational efficiency.
