--description--

As a reminder, this project is being built upon the following starter project on Replit, or cloned from GitHub.

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 Falsy Bouncer challenge.

--instructions--

Within tests/1_unit-tests.js under the test labelled #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.

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=2').then(
    (data) => {
      assert.equal(data.state, 'passed');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

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

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=2').then(
    (data) => {
      assert.equal(data.assertions[0].method, 'isNotOk', 'Null is falsy');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

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

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=2').then(
    (data) => {
      assert.equal(data.assertions[1].method, 'isOk', 'A string is truthy');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

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

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=2').then(
    (data) => {
      assert.equal(data.assertions[2].method, 'isOk', 'true is truthy');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
