Design and Implementation of a Configuration Checking Tool for an After‑Sales System

To support rapid business growth, the after‑sales system requires numerous business‑related configurations (entry points, refund rules, platform settings). These configurations are scattered across different locations, making it easy to miss a setting, which can block processes such as refund requests and cause testers to spend excessive time troubleshooting.

The solution begins by asking three key questions: what constitutes a correct configuration, how to detect configuration errors before they are used, and how to notify the responsible parties. The goal is to maintain a correct baseline configuration sourced from the product side, continuously compare it with the system's current configuration, and provide timely alerts when discrepancies are found.

The resulting design is a configuration‑check tool that operates as follows: (1) Business product adds new configuration in the source system; (2) After the request completes, a listener triggers the tool; (3) A configuration‑source integration service retrieves and filters the source data; (4) A comparison service matches the cleaned source data against the system's configuration; (5) If mismatches are detected, an alert is sent to the business test owner.

After deployment, the tool successfully identifies missing or incorrect configurations, issues alerts, and improves testing efficiency. However, current limitations include partial coverage of configuration types and the fact that the system only alerts rather than automatically correcting the issues, which are areas for future improvement.
