Navbar E2E Test

Let's add cypress E2E tests for the navbar component.

Now that all of our tests are passing, let’s finish this chapter by writing the E2E tests for our navbar.

Navbar E2E test

First, create the file.

touch cypress/integration/navbar.js
Terminal 1
Terminal
Loading...

The above command creates a navbar.js file in the integration directory. Here is the updated code:

navbar.js file

Add first test suite

Within that file, we can write our first few tests.

  1. Similar to our previous E2E tests, start by configuring Cypress’s baseUrl.
  2. Direct Cypress to our home page before each test.
  3. Similar to our unit tests for NavbarComponent, create two describe blocks here for the two different states of our navbar.
  4. Test to verify that clicking the “Signup” link redirects us
