Repeatability

Kind: quality-attribute

Layer: Computation Core

Record: architecture:repeatability

Severity: mandatory

Scope: test, build, process

Canonical: Ontology

The degree to which rerunning the same test or process in the same environment gives the same result.

Listed in Architecture principles, after Reproducibility and before Correctness.
