> Get elements by data attribute by creating a Cy command on the fly

[![NPM][npm-icon] ][npm-url]

## Why

According to the Cypress best practices for [Selecting Elements](https://on.cypress.io/best-practices#Selecting-Elements) using dedicated test id data attributes is the most stable way of finding elements during end-to-end tests. Yet typing the full selector is ... annoying.

```html
<div data-test-id="foo">foo</div>
```
```js
cy.get('[data-test-id="foo"]').should('have.text', 'foo')
```

Who has time for this!

So you could make a little utility function

```js
const tid = s => `[data-test-id="${s}"]`
cy.get(tid('foo')).should('have.text', 'foo')
```

Hmm, sure, but what if your HTML markup has different data attributes? Like this

```html
<div data-test-id="foo">foo</div>
<div data-test="bar">bar</div>
<div test-id="baz">baz</div>
```

Do you need to write 3 different helper functions? No. With `cypress-get-it` you can create data attribute selector _methods_ with descriptive names. In fact, the actual selector will be created _from the method name_ on the fly. You want to get element with `data-test-id=foo`? Just use camel cased words and call `cy.getDataTestId('foo')`. The above elements become

```js
cy.getDataTestId('foo').should('have.text', 'foo')
cy.getDataTest('bar').should('have.text', 'bar')
cy.getTestId('baz').should('have.text', 'baz')
```

![cypress-get-it](https://raw.githubusercontent.com/bahmutov/cypress-get-it/master/img/get-it.png)

So any element attribute like `foo-bar-baz="something"` could be fetched with descriptive `cy.getFooBarBaz("something")`.

## How it works

Load this plugin from your support file and it will replace global `cy` instance with an ES6 Proxy which will intercept any methods calls to `get...` and will call [`cy.get`](https://on.cypress.io/get) with the right selector automatically.

## Install and use

```shell
npm i -D cypress-get-it
```

Require this module from your `cypress/support/index.js`

```js
require('cypress-get-it')
```
