--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>.

isOk() will test for a truthy value, and isNotOk() will test for a falsy value.

To learn more about truthy and falsy values, try our <a href="https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures/basic-algorithm-scripting/falsy-bouncer" target="_blank" rel="noopener noreferrer nofollow">Falsy Bouncer</a> challenge.

--instructions--

Within tests/1_unit-tests.js under the test labeled #3 in the Basic Assertions suite, change each assert to either assert.isOk() or assert.isNotOk() 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=2');
  if (!response.ok) {
    throw new Error(await response.text());
  }
  const data = await response.json();
  assert.equal(data.state, 'passed');

You should choose the correct method for the first assertion - isOk vs. isNotOk.

js
  const response = await fetch(code + '/_api/get-tests?type=unit&n=2');
  if (!response.ok) {
    throw new Error(await response.text());
  }
  const data = await response.json();
  assert.equal(data.assertions[0].method, 'isNotOk', 'Null is falsy');

You should choose the correct method for the second assertion - isOk vs. isNotOk.

js
  const response = await fetch(code + '/_api/get-tests?type=unit&n=2');
  if (!response.ok) {
    throw new Error(await response.text());
  }
  const data = await response.json();
  assert.equal(data.assertions[1].method, 'isOk', 'A string is truthy');

You should choose the correct method for the third assertion - isOk vs. isNotOk.

js
  const response = await fetch(code + '/_api/get-tests?type=unit&n=2');
  if (!response.ok) {
    throw new Error(await response.text());
  }
  const data = await response.json();
  assert.equal(data.assertions[2].method, 'isOk', 'true is truthy');
