worstcasetid

worstcasetid is a term used primarily in informal technical discussions and some test documentation to refer to the identifier associated with the worst-case scenario in a given evaluation. It is not a standardized concept, and its exact meaning depends on the context. In software performance testing, worstcasetid often denotes the thread ID, process ID, test case ID, or time window that yields the maximum observed latency, memory usage, or other resource metrics. The term is typically produced by a test harness or monitoring system that records a set of scenarios and records the one with the worst outcomes.

Origins: The name is a composite of worst case and tid, with tid commonly meaning thread ID in operating systems, but in practice worstcasetid can refer to a test-case ID or timing ID depending on the project's conventions.

Usage: In dashboards, worstcasetid is used to point to the scenario to optimize; it helps teams reproduce the problematic run and identify bottlenecks. It may be reported alongside the associated metrics and the trigger conditions that led to the worst-case outcome.

Limitations: Because it is informal, the interpretation of worstcasetid varies; it is not a formal standard. Relying on it without clarifying the mapping can lead to confusion.
