Struct MetamorphicRelation 

pub struct MetamorphicRelation {
    pub id: String,
    pub description: String,
    pub source_transform: String,
    pub expected_relation: String,
    pub tolerance: f64,
}

A metamorphic relation for testing without oracles.

Per Chen et al. (2018): Metamorphic relations verify invariants without requiring knowledge of the correct output.

Fields

id: String

Unique relation ID (e.g., “MR-PermutationInvariance”).

description: String

Human-readable description.

source_transform: String

Transform to apply to source input.

expected_relation: String

Expected relation between source and follow-up outputs.

tolerance: f64

Tolerance for numerical comparisons.
