Overview of this book

Vue.js is one of the latest new frameworks to have piqued the interest of web developers due to its reactivity, reusable components, and ease of use. This book shows developers how to leverage its features to build high-performing, reactive web interfaces with Vue.js. From the initial structuring to full deployment, this book provides step-by-step guidance to developing an interactive web interface from scratch with Vue.js. You will start by building a simple application in Vue.js which will let you observe its features in action. Delving into more complex concepts, you will learn about reactive data binding, reusable components, plugins, filters, and state management with Vuex. This book will also teach you how to bring reactivity to an existing static application using Vue.js. By the time you finish this book you will have built, tested, and deployed a complete reactive application in Vue.js from scratch.

Summary

Why unit tests?

Before we start writing unit tests, let's try to understand what we're trying to achieve by writing them. Why is unit testing so important? Sometimes when I write my tests, the only thing I can think about is my code coverage; I want to achieve a level of 100%.

Code coverage is a very important metric and helps a lot to understand the code flow and what needs to be tested. But it is not a metric of unit test quality. This is not a metric of a good code quality. You can have your code 100% covered just because you call all your functions in your testing code, but if your assertions are wrong, the code might be wrong as well. Writing good unit tests is an art that requires time and patience. But when your unit tests are good enough and when you are concentrating on making good assertions, with regard to corner cases and branch coverage, they provide the following:

  • Help us to identify failures in algorithms and logic
  • Help us to improve the code quality
  • Make us write code that is...
