Building Robust Applications with Nuxt.js and Testing Its Components
As Vue’s popularity continues to soar, developers are increasingly turning to Nuxt.js to build robust and universal applications. One crucial aspect of building such applications is testing, which helps reduce debugging time and ensures a smoother development process. In this article, we’ll explore how to set up a game store application with Nuxt.js and test its components using Jest.
Getting Started with Nuxt.js
To create a new Nuxt.js application, navigate to your project folder and run the following command in your terminal: npx create-nuxt-app <project-name>. This will take you through a series of options, including selecting Vuetify as your UI framework and Jest as your testing framework.
Configuring the Store
Nuxt.js leverages Vuex to efficiently manage states. Every file created in the /store directory can be treated as a Vuex module, containing its state, mutation, action, and getters. Let’s create a new games.js file in the /store directory and define our game store data.
Displaying Game Data
To display our game data on the main page, we’ll use the v-for directive to iterate through each item. We’ll also use Vuex’s MapGetter helper to map the previously defined getter in games.js to a computed property in our index.vue file.
Configuring Jest for Testing
For our application’s testing framework, we’ll use Jest, which we selected during setup. We’ll configure Jest to use its globalSetup module, which exports an async function that is triggered once before all tests are run. This allows us to choose which particular store we want to test.
Writing Tests for Our Store
Let’s create a new games.test.js file inside the /test directory and write our tests. We’ll use Jest’s beforeAll block to import the built store and beforeEach block to ensure a new store is created each time a separate test is run.
Keeping Tests Simple and Concise
Writing tests for universal applications can be challenging, but a general rule of thumb is to always keep tests simple and concise. By following this approach, we can ensure our tests are efficient and effective.
