--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>.

strictEqual() compares objects using ===.

--instructions--

Within tests/1_unit-tests.js under the test labeled #6 in the Equality suite, change each assert to either assert.strictEqual or assert.notStrictEqual 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=5');
  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 - strictEqual vs. notStrictEqual.

js
  const response = await fetch(code + '/_api/get-tests?type=unit&n=5');
  if (!response.ok) {
    throw new Error(await response.text());
  }
  const data = await response.json();
  assert.equal(
    data.assertions[0].method,
    'notStrictEqual',
    'with strictEqual the type must match'
  );

You should choose the correct method for the second assertion - strictEqual vs. notStrictEqual.

js
  const response = await fetch(code + '/_api/get-tests?type=unit&n=5');
  if (!response.ok) {
    throw new Error(await response.text());
  }
  const data = await response.json();
  assert.equal(data.assertions[1].method, 'strictEqual', '3*2 = 6...');

You should choose the correct method for the third assertion - strictEqual vs. notStrictEqual.

js
  const response = await fetch(code + '/_api/get-tests?type=unit&n=5');
  if (!response.ok) {
    throw new Error(await response.text());
  }
  const data = await response.json();
  assert.equal(
    data.assertions[2].method,
    'strictEqual',
    "6 * '2' is 12. Types match !"
  );

You should choose the correct method for the fourth assertion - strictEqual vs. notStrictEqual.

js
  const response = await fetch(code + '/_api/get-tests?type=unit&n=5');
  if (!response.ok) {
    throw new Error(await response.text());
  }
  const data = await response.json();
  assert.equal(
    data.assertions[3].method,
    'notStrictEqual',
    'Even if they have the same elements, the Arrays are notStrictEqual'
  );
