Architecting Vue.js 3 Enterprise-Ready Web Applications

By: Solomon Eseme

Overview of this book

Building enterprise-ready Vue.js apps entails following best practices for creating high-performance and scalable applications. Complete with step-by-step explanations and best practices outlined, this Vue.js book is a must-read for any developer who works with a large Vue.js codebase where performance and scalability are indispensable. Throughout this book, you’ll learn how to configure and set up Vue.js 3 and the composition API and use it to build real-world applications. You’ll develop the skills to create reusable components and scale performance in Vue.js 3 applications. As you progress, the book guides you in scaling performance with asynchronous lazy loading, image compression, code splitting, and tree shaking. Furthermore, you’ll see how to use the Restful API, Docker, GraphQL, and different types of testing to ensure that your Vue.js 3 application is scalable and maintainable. By the end of this book, you’ll be well-versed in best practices for implementing Restful API, Docker, GraphQL, and testing methods to build and deploy an enterprise-ready Vue.js 3 application of any scale.

Best practices in unit test creation

When creating unit test cases, you should follow the best practices to produce consistent unit test cases to test every possible case properly. Consider the following points to create good test cases:

  • Arrange, Act, and Assert (AAA)
  • Write deterministic tests
  • Write good test names and descriptions
  • Write tests before or during development (TDD)
  • Leverage automated tests
  • Using mocks and stubs

Let’s understand each of these points in more detail in the next subsections.

Arrange, act, and assert

When structuring your unit test suite for enterprise applications, following the AAA approach is recommended to improve readability and easy understanding of your unit test suite. It improves the test readability by giving it a logical flow. It can also be referred to as the Given/When/Then (GWT) strategy.

GWT is a semi-structured way of writing down test cases. These test cases can either be manually tested or...
