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.

Summary

In this chapter, we learned how to write tests in V. We saw the syntax and usage of the assert keyword and learned how to write a simple test and run it. We then learned about the testsuite_begin and testsuite_end functions and learned how to use those functions in performing pre- and post-test activities, respectively. This chapter also covered the popular AAA pattern of writing tests. We also learned how to write tests for functions with optional return types.

In the latter parts of this chapter, we saw various approaches to writing and running tests that span from a simple program to a program with modules. We also learned different approaches to running tests contained in a single file, tests that belong to a module, and also, all tests contained in a project. Finally, we saw how to see the detailed output generated by the test runner using the stats argument. Having learned how to write and run tests in V, you will now be able to write applications in V that are covered...
