- * @description Tests that obj meets the requirements for built-in objects

- * @param {Object} obj the object to be tested.
- * @param {boolean} isFunction whether the specification describes obj as a function.
- * @param {boolean} isConstructor whether the specification describes obj as a constructor.
- * @param {String[]} properties an array with the names of the built-in properties of obj,
- * excluding length, prototype, or properties with non-default attributes.
- * @param {number} length for functions only: the length specified for the function
- * or derived from the argument list.
