Key benefits

  • Write Go test suites using popular mocking and testing frameworks
  • Leverage TDD to implement testing at all levels of web applications and microservices architecture
  • Master the art of writing tests that cover edge cases and concurrent code

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. You’ll 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. You’ll then learn how to structure and run your unit tests using Go’s standard testing library, and explore two popular testing frameworks, Testify and Ginkgo. You’ll also implement test suites using table-driven testing, a popular Go technique. As you advance, you’ll write and run behavior-driven development (BDD) tests using Ginkgo and Godog. Finally, you’ll 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, you’ll have learned how to design and implement a comprehensive testing strategy for your Go applications and microservices architecture.

Who is this book for?

If you are an intermediate-level developer or software testing professional who knows Go fundamentals and is looking to deliver projects with Go, then this book is for you. Knowledge of Go syntax, structs, functions, and interfaces will help you get the most out of this book.

What you will learn

  • Create practical Go unit tests using mocks and assertions with Testify
  • Build table-driven test suites for HTTP web applications
  • Write BDD-style tests using the Ginkgo testing framework
  • Use the Godog testing framework to reliably test web applications
  • Verify microservices architecture using Pact contract testing
  • Develop tests that cover edge cases using property testing and fuzzing

As a newbie with Go I found this book of great benefit.Adelina has covered the fundamentals of coding and design, not just testing.Testing in particular I found I found challenging to understand, as I don’t feel the testing library provides much guidance by itself. I appreciated that the book covered the entire testing pyramid and applies it to web apps. Really looking forward to digging into the code on GitHub too!

I got this book on a recommendation from a friend, suggesting it would be a good entry to the language. Having just finished it, I can confirm it was a great suggestion - the book covers testing principles in depth (applicable to all languages), then holds your hand getting into the nuts and bolts of Go, and Go testing with the Github resources. I found the book easy to follow, though some video resources might have been a nice addition to code along to.Definitely would recommend as a really helpful intro to Go and Go testing.

I wish we had a book like this one in 2000 when I was learning to code.This is the way how programming shall be taught, tests first.Adelina manages to mention both the necessary details of testing and agile development.Then she describes how to build projects, step by step, TDD way.As expected, all code is on GitHub which makes it easier to follow, in case you skim through pages.I am yet to check chapters on testing apps with databases and performance testing, but what I have seen so far is of very high quality.The only thing I didn’t like is that the book is not linked to some youtube playlist, which could have shown how to actually code those apps from scratch, TDD way.Probably that’s a little too much to ask for from a book :)I believe this book can be turned into a university course on GoLang, a really good one.

I’ve been a Java engineer for a few years and have relatively recently transitioned to Go. I found this book to be an excellent resource in learning how to write src and test code “the Go way”. The testing techniques discussed were explained using practical examples that are relevant to production systems. Although not the focus of the book, some discussion of testing as part of the CI/CD pipeline would have been insightful.

Test-Driven Development in Go is an excellent guide for anyone who wants to learn how to approach complex code bases using TDD or needs a refresher on writing tests in Go. The book takes a generic perspective on TDD, using Go as a means to clearly explain how to write clean, scalable, and maintainable tests.The second chapter focuses on how to write effective tests using a variety of tools and techniques.In the third chapter, the author introduces SOLID design principles and dependencies, which leads to the usage of dependency injection and interfaces in Go. After a detailed overview of the mechanics of composition and dependency injection in Go, the author explains how to use mocks to test more intricate architectures.Chapter four takes the reader through table-driven testing, explaining how the table's layout should be arranged in edge, boundary, and base cases, and how to identify these.The second part of the book explores integration and end-to-end testing, refactoring, and tests in the context of a microservice architecture.In the fifth chapter, the author provides a detailed explanation of how to write integration tests, including how to use the httptest module and how to use BDD with Ginkgo.Chapter six provides a step-by-step guide on how to write end-to-end tests using Docker, Docker Compose, and Godoc to write the test specs.Chapter seven ties all the concepts together and describes approaches for refactoring and how a software developer can rely on a solid and well-structured test suite to fearlessly refactor a complex code base.In chapter eight, the author introduces pprof and explains how to instrument the code to understand performance bottlenecks. This chapter also touches on monitoring and observability in the context of preparing a code base for production.In my opinion, the best part of the book is the third and final part, where the author introduces testing for concurrent code, edge cases, and generics.Chapter nine provides a complex yet straightforward example of detecting race conditions and deadlocks.Chapter ten introduces two new techniques that have been embraced by the community: fuzzing and property-based testing. No book about Go is complete without a chapter on generics, and in chapter eleven, the author reworks the table-driven tests from chapter four using generics.In summary, the book covers the phases of structuring and developing a solid and agile test suite, covers best practices, and uses practical examples to clearly explain the ideas behind the concepts. Adelina is a seasoned software developer turned developer advocate who can describe complex ideas in a simple and clear way, demonstrating her deep understanding of the concepts. I highly recommend this book to anyone looking to improve their testing skills in Go.

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready? Chevron down icon Chevron up icon

We'll let you know every time there has been an update to a course that you've bought in Early Access.
