--description--

As a reminder, this project is being built upon the following starter project cloned from <a href="https://github.com/freeCodeCamp/boilerplate-mochachai/" target="_blank" rel="noopener noreferrer nofollow">GitHub</a>.

include() and notInclude() work for strings too! include() asserts that the actual string contains the expected substring.

--instructions--

Within tests/1_unit-tests.js under the test labeled #14 in the Strings 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.

--hints--

All tests should pass.

js
const response = await fetch(code + '/_api/get-tests?type=unit&n=13');
if (!response.ok) {
  throw Error(await response.text());
}
const data = await response.json();
assert.equal(data.state, 'passed');

You should choose the correct method for the first assertion - include vs. notInclude.

js
const response = await fetch(code + '/_api/get-tests?type=unit&n=13');
if (!response.ok) {
  throw Error(await response.text());
}
const data = await response.json();
assert.equal(
  data.assertions[0].method,
  'include',
  "'Arrow' contains 'row'..."
);

  data.assertions[1].method,
  'notInclude',
  "... a 'dart' doesn't contain a 'queue'"
