Comprehensive Stress Test Scope Evaluation: Adding and Subtracting Approaches

Stress testing is an essential phase for any project, and accurately defining its scope is a critical step. The article first outlines four comprehensive "addition" methods to gather the full set of scenarios that may need testing: collecting QA requirements from the project team, consulting a test‑case library of past issues, conducting test‑case reviews with developers and QA, and analyzing the server architecture to enumerate all possible entry points.

Using a friend‑system example, the author demonstrates how to build a requirement table, extract historical stress‑test focus areas, and involve multiple stakeholders (developers, QA, test engineers) in reviewing test cases.

The second part introduces "precision" or "subtraction" techniques to prioritize and trim the test set. It emphasizes clarifying the project's stress‑test goals (player count, regions, feature scope, timeline) and continuously syncing with the team. Historical interface call volumes and high‑frequency interface statistics are used to rank features, with a custom tool that aggregates RPC logs to produce call‑frequency reports.

Results from a recent project show a stark contrast between the 57 test cases identified by the addition methods and the 648 interfaces discovered via code scanning; the precision step narrows the final set to 122 cases covering 18 scenarios, balancing coverage and effort.

Finally, the article summarizes that a combination of additive and subtractive evaluations—leveraging requirement collection, case libraries, reviews, architecture analysis, goal clarification, historical data, and frequency tools—yields an effective, scalable stress‑test scope applicable not only to performance testing but also to functional and interface testing.
