[puppeteer](https://github.com/GoogleChrome/puppeteer) + [@testing-library/dom](https://github.com/testing-library/dom-testing-library) = 💖

All your favorite user-centric querying functions from @testing-library/react & @testing-library/library available from Puppeteer!

## Install

`npm install --save-dev pptr-testing-library`

## Use

```js

const puppeteer = require('puppeteer')

const {getDocument, queries, waitFor} = require('pptr-testing-library')

const {getByTestId, getByLabelText} = queries

const browser = await puppeteer.launch()

const page = await browser.newPage()

// Grab ElementHandle for document

const $document = await getDocument(page)

// Your favorite query methods are available

const $form = await getByTestId($document, 'my-form')

// returned elements are ElementHandles too!

const $email = await getByLabelText($form, 'Email')

// interact with puppeteer like usual

await $email.type('[email protected]')

// waiting works too!

await waitFor(() => getByText($document, 'Loading...'))

```

A little too un-puppeteer for you? We've got prototype-mucking covered too :)

```js

const puppeteer = require('puppeteer')

require('pptr-testing-library/extend')

const browser = await puppeteer.launch()

const page = await browser.newPage()

// getDocument is added to prototype of Page

const $document = await page.getDocument()

// query methods are added directly to prototype of ElementHandle

const $form = await $document.getByTestId('my-form')

// destructing works if you explicitly call getQueriesForElement

const {getByText} = $form.getQueriesForElement()

// ...

```

## Version Compat

| Puppeteer Version | pptr-testing-library Version |

| ----------------- | ---------------------------- |

| 17+               | >0.8.0                       |

| <17               | 0.7.x                        |

## API

Unique methods, not part of `@testing-library/dom`

- `getDocument(page: puppeteer.Page): ElementHandle` - get an ElementHandle for the document

- `wait(conditionFn: () => {}): Promise<{}>` - wait for the condition to not throw (wrapper around `waitForExpect`)

---

[@testing-library/dom API](https://github.com/testing-library/dom-testing-library#usage). All `get*`/`query*` methods are supported.

- `getQueriesForElement(handle: ElementHandle): ElementHandle & QueryUtils` - extend the input object with the query API and return it

- `getNodeText(handle: ElementHandle): Promise` - get the text content of the element

- `queries: QueryUtils` - the query subset of `@testing-library/dom` exports

  - `queryByPlaceholderText`

  - `queryAllByPlaceholderText`

  - `getByPlaceholderText`

  - `getAllByPlaceholderText`

  - `findByPlaceholderText`

  - `findAllByPlaceholderText`

  - `queryByText`

  - `queryAllByText`

  - `getByText`

  - `getAllByText`

  - `findByText`

  - `findAllByText`

  - `queryByLabelText`

  - `queryAllByLabelText`

  - `getByLabelText`

  - `getAllByLabelText`

  - `findByLabelText`

  - `findAllByLabelText`

  - `queryByAltText`

  - `queryAllByAltText`

  - `getByAltText`

  - `getAllByAltText`

  - `findByAltText`

  - `findAllByAltText`

  - `queryByTestId`

  - `queryAllByTestId`

  - `getByTestId`

  - `getAllByTestId`

  - `findByTestId`

  - `findAllByTestId`

  - `queryByTitle`

  - `queryAllByTitle`

  - `getByTitle`

  - `getAllByTitle`

  - `findByTitle`

  - `findAllByTitle`

  - `queryByRole`

  - `queryAllByRole`

  - `getByRole`

  - `getAllByRole`

  - `findByRole`

  - `findAllByRole`

  - `queryByDisplayValue`,

  - `queryAllByDisplayValue`,

  - `getByDisplayValue`,

  - `getAllByDisplayValue`,

  - `findByDisplayValue`,

  - `findAllByDisplayValue`,

## Known Limitations

- Async utilities `waitForElement`, `waitForElementToBeRemoved` and `waitForDomChange` are not exposed. Consider using a `find*` query.

- `fireEvent` method is not exposed, use puppeteer's built-ins instead.

- `expect` assertion extensions are not available.

## Special Thanks

[@testing-library/dom](https://github.com/testing-library/dom-testing-library) of course!
