Terminology

2205 terms, tools, patterns and metrics an architect is expected to use precisely. Each one gets a short explanation of what it is, and — where it matters — what it is commonly confused with. Search filters as you type; the column headers sort.

Term	Kind	Topic	What it is
Breaking-Point Testing Test to Failure, Constraint Discovery	practice	Load Testing	Pushing a load test past the target until the system fails, because the purpose of a load test is to locate the constraint and the failure mode rather than to confirm a number.
Coordinated Omission Closed-Loop Measurement Bias, Omitted Latency Samples	concept	Load Testing	The measurement error in which a load generator stops issuing requests while the system under test is stalled, so the slow samples that a real arrival process would have produced are never recorded.
Load Testing in Practice	practice	Load Testing	Verifying behaviour under expected load — where realism of workload and data matters more than the number of virtual users.
Workload Model	practice	Load Testing	A description of the traffic mix, arrival pattern and data distribution a load test reproduces, which determines whether the test's results mean anything.
