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. Ensuring the safety and security of your web applications is critical.

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

The snapshots generated are the source of truth for deciding if a test is valid or not. That's the way regressions are checked, and in the end, it depends on your criteria.

## Example

For example, go to the `ContactBox.vue` component and change the `fullName` computed prop to be separated by a comma:
