[![Build Status](https://travis-ci.org/kentor/flush-promises.svg)](https://travis-ci.org/kentor/flush-promises) [![npm](https://img.shields.io/npm/v/flush-promises.svg)](https://www.npmjs.com/package/flush-promises)

Flush all pending resolved promise handlers. Useful in tests.

## example with async/await

```js

const flushPromises = require('flush-promises');

test('flushPromises', async () => {

  let a;

  let b;

  Promise.resolve().then(() => {

    a = 1;

  }).then(() => {

    b = 2;

  })

  await flushPromises();

  expect(a).toBe(1);

  expect(b).toBe(2);

});

```

## TypeScript

```ts

import flushPromises from "flush-promises";

test("flushPromises", async () => {

  let a;

  let b;

 

  Promise.resolve().then(() => {

    a = 1;

  }).then(() => {

    b = 2;

  });

 

  await flushPromises();

 

  expect(a).toBe(1);

  expect(b).toBe(2);

});

```
