How to test the WeChat Moments posting feature: an engineering breakdown from test cases to exception paths

Testing the WeChat Moments posting feature cannot be limited to checking whether the page shows a success message; it must cover three levels: functional correctness, business correctness, and system reliability. The article breaks out test cases TC01–TC10 across four dimensions: input and boundaries, business rules, permissions and privacy, and exceptions and recovery. It focuses on verifying that partial-visibility permissions must be checked separately with three accounts—the publisher, an authorized viewer, and an unauthorized viewer—and on how to avoid duplicate posts when the server has already saved the post after a request timeout but the client has not received a response. AI can generate initial test cases, but manual review, automated execution, and result verification are still needed to form a closed verification loop.
