Feature Test II: Setup

Now that we are in the green we should take a moment to consider refactoring our code.

Our code is pretty basic and succinct. We won’t refactor it but will take a moment to consider our current code implementation.

For more on the refactor phase, you can try the Codecademy Learn Test Driven Development With Mocha Course.

Feature Test II

Returning to our poetry app demo, we want to write a test to check if the application saves the title and text of a user’s poem when they press the submit button.

The functionality we want to test is:

  1. The user enters text into a text input element (the poem)
  2. The user enters text into a second text input element (the title of the poem)
  3. The user presses a submit button

Adding the describe and it blocks for this second test would look like this:

describe('demo poetry web app', () => { it('saves the user poem and title', () => { }); });

Next, we want to write the setup, exercise, and verification phases of our test.

In the setup phase for this test, we create variables to represent a user’s input to the title and poem fields on the home page.

const title = 'Words Birth Worlds'; const poem = 'Our words are marvelous weapons with which we could behead the sun';

The second test would now look like this:

describe('demo poetry web app', () => { it('saves the user poem and title', () => { const title = 'Words Birth Worlds'; const poem = 'Our words are marvelous weapons with which we could behead the sun'; }); });

Instructions

1.

Go to your test suite for the message app in the user-visits-root-test.js file. Notice that we have added the describe and it blocks for your second test. Inside those blocks:

  • Create a const variable named message to hold the expected value of the message input, and set it equal to a string with the value:

  • Below message, create a const variable named author to hold the expected value of the author input, and set it equal to username.
