High Level DOM Assertions for [QUnit](https://qunitjs.com/)

```js
assert.dom('h1').exists();
assert.dom('h1').hasClass('title');
assert.dom('h1').hasText('Welcome to Ember, John Doe!');

assert.dom('input').isFocused();
assert.dom('input').hasValue(/.+ Doe/);
assert.dom('input').hasAttribute('type', 'text');
```

Install
------------------------------------------------------------------------------

### npm

```bash
npm install --save-dev qunit-dom
```

or using [`yarn`](https://yarnpkg.com/):

```bash
yarn add --dev qunit-dom
```

### Ember projects using `ember-qunit` v6.x and above

Import and run the `setup` function in your `test-helper.js` file:

```js
// tests/test-helper.js
import * as QUnit from 'qunit';
import { setup } from 'qunit-dom';

//...

setup(QUnit.assert);

setApplication(Application.create(config.APP));

start();

//...
```

This will attach the APIs to QUnit's `assert` object.

### Ember projects using &lt; v6.x of ember-qunit

Install qunit-dom v2.0.0

### `<script>` Tag

Load `qunit-dom.js` *after* `qunit.js`:

```html
<script src="https://unpkg.com/qunitjs/qunit/qunit.js"></script>
<script src="https://unpkg.com/qunit-dom/dist/qunit-dom.js"></script>
```

Usage
------------------------------------------------------------------------------

Once installed the DOM element assertions are available at `assert.dom(...).*`:

```js
test('the title is welcoming', function(assert) {
  assert.dom('#title').hasText('Welcome to QUnit');
});
```

**All available assertions are documented in [API.md](API.md).**

A basic codemod to automatically convert your assertions is available at
[https://github.com/simplabs/qunit-dom-codemod](https://github.com/simplabs/qunit-dom-codemod).

### TypeScript

`qunit-dom` includes type definition files, but the way it extends QUnit means
that you need import it somewhere so that TS and your editor can pick up the
types. It is recommended to add the following line to your
`tests/test-helper.ts` file:

```
import 'qunit-dom';
```

Rename your `tests/test-helper.js` to `.ts` if you do not have such a
file yet.
