Book excerpt: What does it mean to program with confidence? How do you build self-testing software? What even is a test, anyway? Bestselling Go writer and teacher John Arundel tackles these questions, and many more, in his follow-up to the highly successful The Power of Go: Tools. Welcome to the thrilling world of fuzzy mutants and spies, guerilla testing, mocks and crocks, design smells, mirage tests, deep abstractions, exploding pointers, sentinels and six-year-old astronauts, coverage ratchets and golden files, singletons and walking skeletons, canaries and smelly suites, flaky tests and concurrent callbacks, fakes, CRUD methods, infinite defects, brittle tests, wibbly-wobby timey-wimey stuff, adapters and ambassadors, tests that fail only at midnight, and gremlins that steal from the player during the hours of darkness. “If you get fired as a result of applying the advice in this book, then that’s probably for the best, all things considered. But if it happens, I’ll make it my personal mission to get you a job with a better company: one where people are rewarded, not punished, for producing software that actually works.” Go’s built-in support for testing puts tests front and centre of any software project, from command-line tools to sophisticated backend servers and APIs. This accessible, amusing book will introduce you to all Go’s testing facilities, show you how to use them to write tests for the trickiest things, and distils the collected wisdom of the Go community on best practices for testing Go programs. Crammed with hundreds of code examples, the book uses real tests and real problems to show you exactly what to do, step by step. You’ll learn how to use tests to design programs that solve user problems, how to build reliable codebases on solid foundations, and how tests can help you tackle horrible, bug-riddled legacy codebases and make them a nicer place to live. From choosing informative, behaviour-focused names for your tests to clever, powerful techniques for managing test dependencies like databases and concurrent servers, The Power of Go: Tests has everything you need to master the art of testing in Go.
