types-testing/dist/lib/compiler/validate-assertion.js

Test TypeScript types at test runner runtime - Works seamlessly with Jest, Vitest, and Bun.

const validateAssertion = (assertionFn, params) => {
  const result = assertionFn(
    params.checker,
    params.receivedType,
    params.expectedType
  );
  return params.isNegated ? !result : result;
};
export {
  validateAssertion
};
