## Description

<section id='description'>

As a reminder, this project is being built upon the following starter project on <a href="https://repl.it/github/freeCodeCamp/boilerplate-mochachai">Repl.it</a>, or cloned from <a href='https://github.com/freeCodeCamp/boilerplate-mochachai/'>GitHub</a>.

## Instructions

<section id='instructions'>

Within `tests/1_unit-tests.js` under the test labelled `#12` in the `Arrays` suite, change each `assert` to either `assert.include` or `assert.notInclude` to make the test pass (should evaluate to `true`). Do not alter the arguments passed to the asserts.

## Tests

<section id='tests'>

```yml
tests:
  - text: All tests should pass.
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=11').then(data => { assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: You should choose the correct method for the first assertion - `include` vs. `notInclude`.
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=11').then(data => {  assert.equal(data.assertions[0].method, 'notInclude', 'It\'s summer in july...'); }, xhr => { throw new Error(xhr.responseText); })
  - text: You should choose the correct method for the second assertion - `include` vs. `notInclude`.
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=11').then(data => {  assert.equal(data.assertions[1].method, 'include', 'JavaScript is a backend language !!'); }, xhr => { throw new Error(xhr.responseText); })
