freeCodeCamp Challenge Guide: Run Functional Tests using a Headless Browser II

Run Functional Tests using a Headless Browser II

Problem Explanation

To begin, open the file “tests/2_functional_tests.js” and locate the browser based tests.

Change the link to the current URL of your project if you are completing this challenge online. If you are using a local development environment, replace the line with Browser.localhost('', (process.env.PORT || 3000));.

Find test ‘submit “surname” : “Vespucci” - write your e2e test…’ and check the challenge page for the expected values in order to pass this challenge.


Hint 1

Using the example above, look at how the form is being submitted, and how the assertions are making comparisons between the expected and actual values of the response.

Hint 2

Fill the broswer with a surname of Vespucci, then use pressButton to submit.

Hint 3

In the callback for pressButton, all assertions should be browser.assert in order to correctly pass.

Hint 4

Replace the statement with your own tests based on the instructions in the comments. Check the example above for syntax if you get stuck.

Hint 5

Check the tests on the challenge page or the instructions in the comments for expected values.

Hint 6

Make sure your done() call is within the pressButton callback.


Solution #1(Click to Show/Hide)
test('submit "surname" : "Vespucci" - write your e2e test...', function(done) {
  // fill the form, and submit.
  browser.fill('surname', 'Vespucci').pressButton('submit', function() {
    // assert that status is OK 200
    // assert that the text inside the element 'span#name' is 'Amerigo'
    browser.assert.text('span#name', 'Amerigo');
    // assert that the text inside the element 'span#surname' is 'Vespucci'
    browser.assert.text('span#surname', 'Vespucci');
    // assert that the element(s) 'span#dates' exist and their count is 1
    browser.assert.element('span#dates', 1);
