By: Navule Pavan Kumar Rao

Overview of this book

A new language on the block, V comes with a promising set of features such as fast compilation and interoperability with other programming languages. This is the first book on the V programming language, packed with concise information and a walkthrough of all the features you need to know to get started with the language. The book begins by covering the fundamentals to help you learn about the basic features of V and the suite of built-in libraries available within the V ecosystem. You'll become familiar with primitive data types, declaring variables, arrays, and maps. In addition to basic programming, you'll develop a solid understanding of the building blocks of programming, including functions, structs, and modules in the V programming language. As you advance through the chapters, you'll learn how to implement concurrency in V Programming, and finally learn how to write test cases for functions. This book takes you through an end-to-end project that will guide you to build fast and maintainable RESTful microservices by leveraging the power of V and its built-in libraries. By the end of this V programming book, you'll be well-versed with the V programming language and be able to start writing your own programs and applications.

Chapter 12: Testing

Writing tests is an essential part of developing maintainable software applications. Tests ensure that a certain function that is implemented as part of the software works as expected in various scenarios. Proofing the software applications with tests ensures that the application works as expected. So, if there are any changes made to the core logic in the future or if you are extending the functionality, the existing tests scenarios will help you identify how the new changes affect the existing behavior.

In this chapter, we will cover the following topics:

  • Introduction to tests in V
  • Understanding testsuite functions
  • AAA pattern of writing tests
  • Writing tests for functions with optional return types
  • Approaches to writing and running tests

By the end of this chapter, you will know how to write tests for simple programs written in V and for programs that have modules. You will know different approaches to running tests and the benefit...
