--description--

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

match() asserts that the actual value matches the second argument regular expression.

--instructions--

Within tests/1_unit-tests.js under the test labelled #15 in the Strings suite, change each assert to either assert.match or assert.notMatch 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=14').then(
    (data) => {
      assert.equal(data.state, 'passed');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

You should choose the correct method for the first assertion - match vs. notMatch.

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=14').then(
    (data) => {
      assert.equal(
        data.assertions[0].method,
        'match',
        "'# name:John Doe, age:35' matches the regex"
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

You should choose the correct method for the second assertion - match vs. notMatch.

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=14').then(
    (data) => {
      assert.equal(
        data.assertions[1].method,
        'notMatch',
        "'# name:Paul Smith III, age:twenty-four' does not match the regex (the age must be numeric)"
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
