In proof assistants based on dependent type theory, logical equivalence tests may prove too many unrelated statement pairs because of the power of the prover, leading to overly permissive equivalence judgments.

VerifiedThe core principle of formal verification tools is type theory or higher-order logic, which transforms mathematical correctness into a mechanically checkable computational problem.79% similarUnverifiedPassing self-written tests does not equal passing verification against the original behavior; self-written tests can only verify that the understood logic is self-consistent and cannot guarantee behavioral equivalence with the original in all cases79% similarUnverifiedA syntactically correct quantum test that runs successfully can still contradict the reference verdict, meaning executability does not equal test value.79% similarUnverifiedFormal verification proves the correctness of circuit behavior by mathematically exhausting all possible input states, making it more rigorous than simulation testing.78% similarUnverifiedThe premise of this method is that "correctness can be verified by commands," which applies to projects with high test coverage; for dimensions that cannot be expressed by exit codes, such as UI look and feel and product logic trade-offs, numerical review still falls back to subjective judgment.78% similar
