 * - `expect.not.arrayContaining`
 * - `expect.closedTo`
 * - `expect.objectContaining`

 * This module is largely inspired by {@link https://github.com/allain/expect | x/expect} module by Allain Lalonde.
 *
 * @example
 * ```ts
 * import { expect } from "@std/expect";
 *
 * const x = 6 * 7;
 * expect(x).toEqual(42);
 * expect(x).not.toEqual(0);
 *
 * await expect(Promise.resolve(x)).resolves.toEqual(42);
 * ```
 *
