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 Methods

What should we test in methods? That’s a question that we had when we started doing unit tests. Everything comes down to **testing what that method does**. This means that we need to *avoid calls to any dependency*; so, we’ll need to mock them.

Let's add a submit event to the form in the `Form.vue` component that we created in the last chapter:
