50 Go Testing Mistakes (early access edition)

About the book

The book is a collection of patterns gone wrong. The subtle omissions and non-idiomatic structures that we can find in many Go projects have grown over the years. Each chapter focuses on a specific mistake, drawing from real open source projects deployed in production systems. Then, each chapter offers a clear, testable path to idiomatic improvement. You'll see examples of what went wrong, why it happened, and how to build a more reliable system next time.

My goal isn't to present "one true way" to test, but to help you develop a sharper eye, and the Go idiomatic way of thinking about your code, and more importantly, about your tests. Well-tested code isn't just a safety net. It's critical documentation for software products you build and ship. It gives you and your colleagues the confidence to refactor quickly, release frequently (even on Fridays), and sleep calmly even if you are on-call that night.

What you will learn

If you've ever written tests that pass but don't actually prove anything, or tests that break every time you change a line of code, you're not alone. This book will show you how to avoid those traps, along with 49 others like them. In a nutshell, you will learn how to:

• Avoid flaky and brittle tests that slow down development
• Write clear, focused, and maintainable test cases
• Structure your test suites for scalability and readability
• Use Go's testing tools more effectively
• Use Go tools for fundamental security testing
• Catch subtle bugs early by improving test coverage and design
