Metamorphic Test Design

Derive test candidates from input transformations and expected relations when a direct oracle is limited. Produce MT-## design candidates within the evidence boundary; do not execute tests or claim coverage or pass results.

When to Use

  • Analyze baseline inputs, transformation rules, expected relations, output invariants, randomness, and existing evidence.
  • Preserve selection rationale, evidence gaps, priority, and validation actions.
  • Inputs are incomplete but a bounded first pass can mark items unassessed or blocked.

Output Format Options

  • Use Markdown by default; use tables, JSON, or CSV only when explicitly requested or required by the delivery format.
  • Separate static analysis, unexecuted work, evidence states, and Human decisions; keep items unassessed, blocked, or NOT_RUN when runtime evidence is absent.
