To use DOM Testing Library with [AngularJS](https://angularjs.org/), we’ll write a custom render function. We’ll pass our template and angular module we’d like to use for bootstrapping a mini-app inside a div we create, then use getQueriesForElement for that mini-app container. From there we can use all the regular utilities we enjoy from dom-testing-library.

Kent C Dodds: [00:00] Let's go ahead and make a function called `render`. For our `render` method here with AngularJS, we're going to accept a template and an options object for the modules. We'll just call that `html` and `config`.

### angularjs.test.js
```js
function render(html, config) {

}

test('renders a counter', () => {
  const {getByText} = render(`<my-counter></my-counter>`, {modules: ['myApp']})
  const counter = getByText('0')
  fireEvent.click(counter)
  expect(counter).toHaveTextContent('1')

  fireEvent.click(counter)
  expect(counter).toHaveTextContent('2')
})
```

[00:12] Let's go ahead and make our `container = document.createElement("div")`. Then we'll set the `container.innerHTML` to be that `html`.

[00:22] We'll say `angular.bootstrap(container, config.modules)`. Then we can `return` this `getQueriesForElement` on that `container`. That'll get our test passing.

[00:34] Let's go ahead and add, as a convenience, we'll spread the `getQueriesForElement` and that `container` just in case we want to make queries directly on that `container`.

### angularjs.test.js
```js
function render(html, config) {
  const container = document.createElement('div')
  container.innerHTML = html
  angular.bootstrap(container, config.modules)
  return {
    container,
    ...getQueriesForElement(container),
  }
}
```

[00:44] With that, we get our standard `dom-testing-library` test working by passing the `html` and then the modules for our AngularJS app. Then we create a `div`, which is our `container`.

[00:54] We set the `container.innerHTML`. Then we `.bootstrap` Angular on that `container` with the specific modules that have our direct `div` defined.


The person using your application components shouldn’t have to know or care what framework(s) you used to write your application. Guess what: Neither should your tests. 

This course explores the 

. You’ll get hands-on experience writing tests for any JavaScript framework, giving you the confidence you need to ship your JavaScript application with your framework of choice.

Intro to Use DOM Testing Library to test any JS framework

To use DOM Testing Library with [React](https://reactjs.org/), we’ll write a custom render function that utilizes the getQueriesForElement function. Because React binds all event handlers to the body we’ll have to append our container to the body and we’ll add a cleanup method to unmount the component and cleanup the DOM.

To use DOM Testing Library with [Preact](https://preactjs.com/), we’ll write a custom render function that utilizes the getQueriesForElement function. Because preact re-renders asynchronously, we’ll use a custom fireEventAsync function to ensure that the app has re-rendered after every event we fire. If you like this, checkout [preact-testing-library](https://github.com/antsmartian/preact-testing-library).

To use DOM Testing Library with [jQuery](https://jquery.com/), we’ll create a DOM node and apply our jQuery plugin to that DOM node, then we can use getQueriesForElement on that DOM node to get the queries we need to start writing out our tests.

To use DOM Testing Library with [Dojo](https://dojotoolkit.org/), we’ll write a custom render function that utilizes the getQueriesForElement function and dojo’s widge-core utilities.

To use DOM Testing Library with [HyperApp](https://github.com/jorgebucaran/hyperapp), we’ll write a custom render function that utilizes the getQueriesForElement function. HyperApp renders and re-renders asynchronously, so we’ll use a custom `fireEventAsync` utility function to ensure that the app has re-rendered after every event we fire.

To use DOM Testing Library with [Angular](https://angular.io/), we’ll write a custom render function that utilizes the getQueriesForElement function. Here we need to create a test bed testing module which we’ll use to get a native element for our container.

To use DOM Testing Library with [VueJS](https://vuejs.org/), we’ll write a custom render function that utilizes the getQueriesForElement function. Vue is another library that re-renders asynchronously, so we’ll use that custom fireEventAsync to ensure that we wait until the next tick of the event loop before making further queries. If you enjoy this, checkout [vue-testing-library](https://github.com/dfcook/vue-testing-library).

To use DOM Testing Library with [Mithril](https://mithril.js.org/), we’ll write a custom render function which mounts a mithril component and then utilize the getQueriesForElement function on the container where it’s been mounted. Mithril is unique in how it re-renders so we’ll use dom-testing-library’s `wait` function for our assertions.

To use DOM Testing Library with [Svelte](https://svelte.technology/), we’ll write a custom render function that utilizes the getQueriesForElement function. We’ll take the svelte template and create a constructor for that as well as the data to interpolate. Then we can use dom-testing-library queries as normal.

If you like this, checkout [Svelte Testing Library](https://github.com/testing-library/svelte-testing-library).

To use DOM Testing Library with [from-html](https://github.com/m3g4p0p/from-html), we’ll write a custom render function that utilizes the getQueriesForElement function. In our situation we’ve made a custom “component” class for from-html, we mount that manually and then we can use DOM Testing Library's queries on the container we create.
