/**
 * Util useful to create mocked versions of classes with each of their methods
 * and properties replaced, while being properly checked by TypeScript.
 * @param {Object} methods - Each of this class' methods (key is the method
 * name, value is the implementation).
 * @param {Object} properties - Each of this class' property (key is the
 * property name, value is the implementation).
 * @returns {*} - The mocked class, which should respect its public API.
