Researcher Li Bojie’s “Uncompressible Knowledge Probe” uses random, black‑box API queries to gauge how much irreducible knowledge a large language model retains, allowing an indirect estimate of its effective parameter count and prompting a broader debate on model evaluation and transparency.
The article explains how relying solely on black‑box testing hides critical business‑logic bugs, illustrates three concrete failure scenarios, and offers four practical steps—asking targeted questions, visualizing workflows, designing focused test cases, and monitoring logs and databases—to transition toward gray‑box testing.
Tencent Cloud, in collaboration with Nanjing University, ETH Zurich, and Simon Fraser University, presented two VLDB‑2023 papers introducing PolySI, a black‑box checker for snapshot isolation, and Tesseract, an online, transactional schema‑evolution technique, both demonstrating superior performance and practical impact on modern cloud databases.
This article shares practical insights and foundational principles for software testers, covering essential skills, the underlying logic of black‑box testing, input‑output modeling, and a concise 2W+1H analysis method to help both newcomers and seasoned professionals design effective test strategies.
The article explains core black‑box test case design techniques—including equivalence class partitioning, boundary value analysis, and the scenario method—detailing their principles, example tables, flow diagrams, and practical steps for selecting representative cases to achieve comprehensive coverage despite the impossibility of testing every possible input.
This article introduces the concept and benefits of automated testing frameworks, outlines popular framework types such as module‑based, data‑driven, keyword‑driven, black‑box hybrid and behavior‑driven, and explains how they are integrated with CI clusters, data platforms, and objective reporting to improve real‑time video SDK testing efficiency and reliability.
The article shares a QA newcomer’s one‑year reflection on game testing, covering visible vs invisible aspects, the importance of diff analysis, combining black‑box and white‑box testing, systematic test case recording, bug acceptance, and final delivery practices to improve quality in game development.
