All Implemented Interfaces:

public class Fp6Fp12Test
extends junit.framework.TestCase

Self-validating field-axiom tests for the BLS12-381 pairing field tower.

These tests do not depend on external KAT vectors; they exercise the field laws directly. A correct Fp^6 / Fp^12 implementation must satisfy:

• Ring axioms: associativity, commutativity, distributivity.
• Inverse correctness: a * a^-1 == 1.
• Squaring identity: (a + b)^2 == a^2 + 2*a*b + b^2.
• Fermat's little theorem in the relevant field: a^(q-1) == 1 for nonzero a, where q == p^6 or p^12.
• Subfield embedding: lifting Fp^2 → Fp^6 → Fp^12 preserves arithmetic.
• Conjugation in Fp^12: conjugate^2 == identity, and (a*b).conjugate == a.conjugate * b.conjugate.

Random elements are drawn from a fixed seed so failures are reproducible.
