# expect

[![][ghw badge]][ghw link]

A deno implementation of `expect` in order to write tests in a more `jest` like style.

```typescript

import { expect } from 'https://deno.land/x/expect/mod.ts'

expect(10).toEqual(10)

expect(Promise.resolve(20)).resolves.toEqual(20)

```

```typescript

interface Expected {

  toBe(candidate: any, msg?: string): void

  toEqual(candidate: any, msg?: string): void

  toBeTruthy(msg?: string): void

  toBeFalsy(msg?: string): void

  toBeDefined(msg?: string): void

  toBeInstanceOf(clazz: any, msg?: string): void

  toBeUndefined(msg?: string): void

  toBeNull(msg?: string): void

  toBeNaN(msg?: string): void

  toMatch(pattern: RegExp | string): void

  toHaveProperty(propName: string, msg?: string): void

  toHaveLength(length: number, msg?: string): void

  toContain(item: any, msg?: string): void

  toThrow(error?: RegExp | string, msg?: string): void

  // comparison

  toBeGreaterThan(number: number, msg?: string): void

  toBeGreaterThanOrEqual(number: number, msg?: string): void

  toBeLessThan(number: number, msg?: string): void

  toBeLessThanOrEqual(number: number, msg?: string): void

  // mock calls

  toHaveBeenCalled(): void

  toHaveBeenCalledTimes(times: number): void

  toHaveBeenCalledWith(...args: any[]): void

  toHaveBeenLastCalledWith(...args: any[]): void

  toHaveBeenNthCalledWith(nth: number, ...args: any[]): void

  toHaveReturnedWith(expected: any): void

  toHaveReturned(): void

  toHaveLastReturnedWith(expected: any): void

  toHaveReturnedTimes(times: number): void

  toHaveNthReturnedWith(nth: number, expected: any): void

  not: Expected

  resolves: Expected

  rejects: Expected

}
