/** * This module provides Jest compatible expect assertion functionality. * * Currently this module supports the following functions: * - Common matchers: *   - `toBe` *   - `toEqual` *   - `toStrictEqual` *   - `toMatch` *   - `toMatchObject` *   - `toBeDefined` *   - `toBeUndefined` *   - `toBeNull` *   - `toBeNaN` *   - `toBeTruthy` *   - `toBeFalsy` *   - `toContain` *   - `toContainEqual` *   - `toHaveLength` *   - `toBeGreaterThan` *   - `toBeGreaterThanOrEqual` *   - `toBeLessThan` *   - `toBeLessThanOrEqual` *   - `toBeCloseTo` *   - `toBeInstanceOf` *   - `toThrow` *   - `toHaveProperty` *   - `toHaveLength` * - Mock related matchers: *   - `toHaveBeenCalled` *   - `toHaveBeenCalledTimes` *   - `toHaveBeenCalledWith` *   - `toHaveBeenLastCalledWith` *   - `toHaveBeenNthCalledWith` *   - `toHaveReturned` *   - `toHaveReturnedTimes` *   - `toHaveReturnedWith` *   - `toHaveLastReturnedWith` *   - `toHaveNthReturnedWith` * - Asymmetric matchers: *   - `expect.anything` *   - `expect.any` *   - `expect.arrayContaining` *   - `expect.not.arrayContaining` *   - `expect.closeTo` *   - `expect.stringContaining` *   - `expect.not.stringContaining` *   - `expect.stringMatching` *   - `expect.not.stringMatching` * - Utilities: *   - `expect.addEqualityTester` *   - `expect.extend` * * Only these functions are still not available: * - Matchers: *   - `toMatchSnapShot` *   - `toMatchInlineSnapShot` *   - `toThrowErrorMatchingSnapShot` *   - `toThrowErrorMatchingInlineSnapShot` * - Asymmetric matchers: *   - `expect.objectContaining` *   - `expect.not.objectContaining` * - Utilities: *   - `expect.assertions` *   - `expect.hasAssertions` *   - `expect.addSnapshotSerializer` * * This module is largely inspired by {@link https://github.com/allain/expect | x/expect} module by Allain Lalonde. * * @example * ```ts * import { expect } from "https://deno.land/std@$STD_VERSION/expect/mod.ts"; * * const x = 6 * 7; * expect(x).toEqual(42); * expect(x).not.toEqual(0); * * await expect(Promise.resolve(x)).resolves.toEqual(42); * ``` * * @module */export { expect } from "./expect.ts";export { fn } from "./fn.ts";
