Deepening Functional Testing: Horizontal Expansion and Quality Control

Today we discuss deepening functional testing and its horizontal expansion, aiming to further improve testing capabilities.

The article identifies three major aspects for advanced testing: product control, development quality control, and environment configuration control.

1. Product control involves mastering the project's background knowledge and thoroughly understanding the product's requirement documents; testers must know the industry context, user needs, and specific terminology (e.g., CPT/CPC for commercial advertising) to evaluate functionality effectively.

Additionally, testers should assess whether product features and UI designs are reasonable and whether the implementation aligns with requirements, flagging any design flaws early.

2. Development quality control includes obtaining code access, performing diffs, and ensuring proper version‑control practices. The author shares experiences with SVN (using tags, trunk, and branches) and a streamlined Gitflow model that employs only master, develop, and feature branches for development, testing, and release.

Test cases should be integrated with design documents, and testers need insight into the underlying code logic, database schema, and configuration files to avoid gaps in coverage.

Database considerations involve evaluating table designs for reasonableness (e.g., IoT device‑user data separation) and anticipating the impact of schema changes.

Configuration files—covering databases (MySQL, Redis), message queues (Qbus), distributed config (Qconf), constants, and third‑party parameters—must be understood to prevent hard‑coded values and ensure consistency between test and production environments.

Log management is also crucial: testers should know where logs are generated, their classification (DEBUG, ERROR, etc.), and use them for rapid bug localization, supplementing logs when necessary.

3. Environment configuration control is mentioned briefly, with a note that it will be covered in a future article.
