Mark Winteringham's years leading software testing education at Ministry of Testing show through in this focused guide to web API testing. You learn how to design a testing strategy that fits your project, including contract testing with Pact and exploratory methods, all grounded in real-world examples like the downloadable API sandbox. The book dives into automation techniques, performance, and security testing, helping you move beyond simple coverage metrics to a risk-driven approach. If you’re a software QA professional or an experienced developer wanting to ensure your APIs are robust and maintainable, this book offers practical frameworks without unnecessary jargon.

What started as Gerard Meszaros's deep involvement with agile development and automated testing frameworks evolved into a detailed guide for improving test code quality. In this book, you learn 68 specific patterns to write tests that are easier to understand, maintain, and execute efficiently, illustrated with examples spanning multiple programming languages. Chapters cover everything from foundational test strategies and managing test fixtures to recognizing and eliminating common test "smells" that indicate deeper issues. If you work with xUnit or related frameworks and want to elevate your testing skills beyond the basics, this book offers practical insights tailored for developers, testers, and managers alike.

Kent Beck’s experience as a pioneer of Extreme Programming and patterns is clearly reflected in this hands-on guide to test-driven development (TDD). You learn not just the theory but how to write tests first to drive design, improve code quality, and reduce fear during development. Beck’s step-by-step examples show how TDD encourages better communication and collaboration among team members, making it especially useful for developers who want to build confidence and write maintainable software. If you’re eager to shift from tentative coding to a disciplined, feedback-driven approach, this book offers practical insights, though those unfamiliar with basic testing might find it challenging at first.
