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

The module managers we have in the JavaScript community, mainly ES Modules and CommonJS, don't support project-based paths. They only support relative paths for our own modules and paths for the `node_modules` folder. When a project grows a bit, it's common to see paths such as:

import SomeComponent from "../../../../components/SomeComponent";

Luckily, we have different ways to cope with this in a way that we can define aliases for folders relative to the project root, so we could write the above line like:

import SomeComponent from "@/components/SomeComponent";

The `@` here is an arbitrary character to define the root project; you can define your own. Let’s see what solutions we have to apply to  module aliasing. Let’s start from where we left off in the last chapter.

# How to Set Up Webpack Aliases?

[Webpack aliases](https://webpack.js.org/configuration/resolve/#resolve-alias) are very simple to set up. You just need to add a `resolve.alias` property in your webpack configuration. If you take a look at the `build/webpack.base.conf.js`, it has already defined this:

In this lesson, we will be exploring Webpack aliases.
