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

Computed properties and watchers are reactive parts of the logic of Vue.js components. They both serve totally different purposes. One is synchronous and the other asynchronous, which makes them behave slightly differently from each other.

In this chapter, we’ll test them and see what different cases we can find on the way.

## Computed Properties

Computed properties are simple reactive functions that return data in another form. They behave exactly like the language standard `get/set` properties:
