Learn about the Go testing fundamentals and techniques to leverage Test-Driven Development, (TDD) for delivering and maintaining microservice architectures, including unit testing, end-to-end testing, and contract testing.

Key Features

Write Go test suites using popular mocking and assertion frameworks
Leverage TDD to implement end-to-end testing of HTTP web applications and microservice architectures
Master testing and debugging techniques for suites that cover edge cases and concurrent code

Book Description

Experienced developers know that designing a comprehensive testing strategy is vital to shipping and maintaining services in production. This book teaches you to leverage TDD, which is already an industry practice, for testing your Go applications at different levels. In addition, one chapter discusses the challenges and approaches of testing concurrent code, which requires different techniques for testing and profiling.

Youll use TDD to solve and test a variety of problems, from simple mathematical functions to web applications. Youll learn how to structure and run your unit tests, and what assertion frameworks are available for you to use. Youll implement test suites using table-driven testing, which is a common technique used in Go. Then, youll write and run Behavior-Driven Development (BDD) style tests. Youll learn more complex topics that require end-to-end testing with mocking and contract testing via practical examples. Finally, youll explore the difficult aspects of implementing and running TDD in production. Youll come across the challenges of testing concurrent code and fuzzing.

By the end of this book, youll design and implement a comprehensive testing strategy for your Go applications and microservice architectures.

Master the art of writing tests that cover edge cases and concurrent code

Book Description

Experienced developers understand the importance of designing a comprehensive testing strategy to ensure efficient shipping and maintaining services in production. This book shows you how to utilize test-driven development (TDD), a widely adopted industry practice, for testing your Go apps at different levels. Youll also explore challenges faced in testing concurrent code, and learn how to leverage generics and write fuzz tests.

The book begins by teaching you how to use TDD to tackle various problems, from simple mathematical functions to web apps. Youll then learn how to structure and run your unit tests using Gos standard testing library, and explore two popular testing frameworks, Testify and Ginkgo. Youll also implement test suites using table-driven testing, a popular Go technique. As you advance, youll write and run behavior-driven development (BDD) tests using Ginkgo and Godog. Finally, youll explore the tricky aspects of implementing and testing TDD in production, such as refactoring your code and testing microservices architecture with contract testing implemented with Pact. All these techniques will be demonstrated using an example REST API, as well as smaller bespoke code examples.

By the end of this book, youll have learned how to design and implement a comprehensive testing strategy for your Go applications and microservices architecture.

What you will learn

Build table-driven test suites for HTTP web applications
Write BDD-style tests using the Ginkgo testing framework
