Vue.js 2 Design Patterns and Best Practices

By: Paul Halliday

Overview of this book

Vue.js 2 Design Patterns and Best Practices starts by comparing Vue.js with other frameworks and setting up the development environment for your application, and gradually moves on to writing and styling clean, maintainable, and reusable Vue.js components that can be used across your application. Further on, you'll look at common UI patterns, Vue form submission, and various modifiers such as lazy binding, number typecasting, and string trimming to create better UIs. You will also explore best practices for integrating HTTP into Vue.js applications to create an application with dynamic data. Routing is a vitally important part of any SPA, so you will focus on the vue-router and explore routing a user between multiple pages. Next, you'll also explore state management with Vuex, write testable code for your application, and create performant, server-side rendered applications with Nuxt. Toward the end, we'll look at common antipatterns to avoid, saving you from a lot of trial and error and development headaches. By the end of this book, you'll be on your way to becoming an expert Vue developer who can leverage design patterns to efficiently architect the design of your application and write clean and maintainable code.

Chapter 10. Testing Vue.js Applications

In a world with tight deadliness and accelerating requirements, creating automated tests for our applications becomes more important than ever. An important factor to consider, which most developers overlook, is the fact that testing is a skill, and just because you may be comfortable coding up solutions, it doesn't automatically mean that you can write good unit tests. As you get more experience in this area, you'll find yourself writing tests more often and wonder what you ever did without them!

By the end of this chapter, we will cover the following:

  • Learning about why you should consider using automated testing tools and techniques
  • Writing your first unit test for Vue components
  • Writing tests that mock out particular functions
  • Writing tests that are dependent on Vue.js events
  • Using Wallaby.js to see the results of our tests in real time

When we talk about testing our Vue projects, we can mean different things, depending on the context.
