Front-end frameworks, in general, are exploding in popularity, and Vue.js, in particular, has become one of the most popular ones.

As front-end frameworks continue to grow in usage, the ability to incorporate testing has become an essential feature. It's simply the only scalable way to ensure your app is functioning as expected.

You can learn to test your Vue.js applications thoroughly using Jest with this interactive course.

You'll start by learning the simplest unit tests in Jest, and will gradually build up to more intricate tests of different Vue components. To give you practical front-end testing experience, you'll be running your tests on a predefined data rendering Vue.js application.

This course is essential for anyone looking to create robust and effective front-end tests for their Vue apps.

Testing Vue.js Components with Jest

# Testing Components Using Deep Rendering 

## Step 1:

To test MessageList with Deep Rendering, we just need to use `mount` instead of `shallowMount` from the previously created `test/MessageList.test.js`:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>vue-test</title>
  </head>
  <body>
    <div id="app"></div>
    
  </body>
</html>

Typescript React

> Have you noticed the `beforeEach` thing at line number 7? That’s a clean way to create a clean component before each test, which is very important in unit testing since it defines that the tests shouldn’t depend on each other.

Both `mount` and `shallowMount` use exactly the same API; the difference is in the rendering.

## Step 2:

Now press the `RUN` button.

In this lesson, we will test components with Deep Rendering.
