E2E Tests for Signup Component

Explore how to create comprehensive end-to-end tests for the signup component in an Angular app using Cypress. Understand test structure, command chaining, and assertions to validate user interactions, form submissions, and error messages effectively.

We'll cover the following...

Our signup test is set up, ready, and running. It’s time to add E2E tests for our signup component. Below is our updated code:

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>LetsGetLunch</title>
  <base href="/">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.ico">
</head>
<body>
  <app-root></app-root>
</body>
</html>
Signup test setup

Signup test

  1. Utilize an it, passing it the title of our test, followed by a function containing the test itself.

  2. Begin the test with cy and then follow that with a series of chained methods provided by Cypress to interact with the browser.

  3. The first method is .visit('/signup'). Because we configured our baseUrl earlier, we don’t need to provide the full path here. Simply append whatever comes after http://0.0.0.0:8081.

  4. Chain .visit('/signup') with .url(), which receives the current URL.

  5. Chain .url() with an assertion using .should(). Pass it two arguments:

    • Chainer argument
    • Expected value argument

The final result is a statement indicating that the URL should include signup. ...
