## Installation

This module is distributed via `npm` and should be installed as one of your
project's `devDependencies`:

```
npm install --save-dev @testing-library/vue
```

This library has `peerDependencies` listings for `Vue 3` and
`@vue/compiler-sfc`.

You may also be interested in installing `jest-dom` so you can use [the custom
Jest matchers][jest-dom].

If you're using Vue 2, please install version 5 of the library:

```
npm install --save-dev @testing-library/vue@^5
```


## A basic example

```html
<template>
  <p>Times clicked: {{ count }}</p>
  <button @click="increment">increment</button>
</template>

<script>
  export default {
    name: 'Button',
    data: () => ({
      count: 0,
    }),
    methods: {
      increment() {
        this.count++
      },
    },
  }
</script>
```

```js
import {render, screen, fireEvent} from '@testing-library/vue'
import Button from './Button'

test('increments value on click', async () => {
  // The `render` method renders the component into the document.
  // It also binds to `screen` all the available queries to interact with
  // the component.
  render(Button)

  // queryByText returns the first matching node for the provided text
  // or returns null.
  expect(screen.queryByText('Times clicked: 0')).toBeTruthy()

  // getByText returns the first matching node for the provided text
  // or throws an error.
  const button = screen.getByText('increment')

  // Click a couple of times.
  await fireEvent.click(button)
  await fireEvent.click(button)

  expect(screen.queryByText('Times clicked: 2')).toBeTruthy()
})
```

> You might want to install [`jest-dom`][jest-dom] to add handy assertions such
> as `.toBeInTheDocument()`. In the example above, you could write
> `expect(screen.getByText('Times clicked: 0')).toBeInTheDocument()`.

> Using `byText` queries it's not the only nor the best way to query for
> elements. Read [Which query should I use?][which-query] to discover
> alternatives. In the example above, `getByRole('button', {name: 'increment'})`
> is possibly the best option to get the button element.

## Guiding Principles

> [The more your tests resemble the way your software is used, the more
> confidence they can give you.][guiding-principle]

We try to only expose methods and utilities that encourage you to write tests
that closely resemble how your Vue components are used.

Utilities are included in this project based on the following guiding
principles:

1.  If it relates to rendering components, it deals with DOM nodes rather than
    component instances, nor should it encourage dealing with component
    instances.
2.  It should be generally useful for testing individual Vue components or full
    Vue applications.
3.  Utility implementations and APIs should be simple and flexible.

At the end of the day, what we want is for this library to be pretty
light-weight, simple, and understandable.
