`power-assert` module extends.

- `assert.asyncThrows(block[, error][, message])`

Note: use [assert.rejects(asyncFn, error, message)](https://nodejs.org/api/assert.html#assert_assert_rejects_asyncfn_error_message) instead of this module at Node.js 10.x+.

## Usage

- Add `mocha --require intelli-espower-loader` to your test scripts.

### assert throws with async function

- API: `assert.asyncThrows(block[, error][, message])`, return a promise

```js
it('should throw error', () => {
  return assert.asyncThrows(function* () {
    yield fs.readFile(filepath);
  }, /not exists/);
});

it('should throw error', function* () {
  yield assert.asyncThrows(function* () {
    yield fs.readFile(filepath);
  }, /not exists/);
});

it('should throw error', done => {
  assert.asyncThrows(function* () {
    yield fs.readFile(filepath);
  }, /not exists/).then(done).catch(done);
});
```
