Grenning’s expertise shines in guiding you through evolving both tests and code simultaneously, with practical examples that show how to apply TDD principles directly on embedded hardware. If you’re deeply involved in embedded C programming and want to improve code reliability and maintainability, this book offers specific techniques and insights tailored for your world, though it assumes comfort with C environments and compilers.

Drawing from their deep expertise, Harry Percival and Bob Gregory address the complexities Python developers face when scaling applications. You’ll explore architectural patterns like hexagonal and clean architecture, domain-driven design distinctions among Entities and Aggregates, and event-driven microservices—all demonstrated with clear Python code. The book equips you to manage growing application complexity while maximizing your test suites’ effectiveness, especially through patterns like Command-query responsibility segregation and repository management. If you’re immersed in Python development and want practical ways to integrate TDD with robust architectural design, this guide offers a focused, example-rich path forward.

When Harry Percival discovered the power of writing tests before code, he reshaped how developers approach building web applications. This book guides you through creating a full web app using Python, Django, Selenium, and JavaScript, emphasizing writing tests to drive development. You'll learn to write unit and functional tests, use mocks effectively, and automate deployments, gaining skills that improve code reliability and design simplicity. If you're comfortable with Python and want to deepen your web development craft while mastering TDD, this book offers a detailed, example-driven path that demands dedication but rewards with cleaner, more maintainable software.

This tailored guide provides a focused framework for implementing test-driven development (TDD) specifically within embedded C programming environments. It integrates foundational TDD principles with detailed methodologies adapted for the constraints and challenges of embedded systems, such as hardware interfacing and resource limitations. The book offers practical workflows, test harness setups, and debugging strategies that align with your particular embedded project requirements and proficiency level. By tailoring content to your development context and goals, it cuts through generic advice to deliver a personalized framework that enhances code reliability, maintainability, and test coverage in embedded C applications.

Kent Beck, renowned for shaping software engineering with his pioneering work on patterns and Extreme Programming, offers an insightful dive into test-driven development (TDD) that moves beyond theory into hands-on practice. Drawing from his extensive experience, Beck shows you how TDD can transform fear and uncertainty in coding into confidence and clarity by iteratively writing tests then code, exemplified through detailed examples and refactoring techniques across chapters. You gain a clear framework for improving code quality, fostering better communication among team members, and embracing constructive feedback, all of which benefit developers aiming to enhance their craft and teams seeking smoother collaboration. This book is especially useful if you want to shift from tentative coding practices to a disciplined approach that fosters continuous improvement and resilience in software projects.

The breakthrough moment came when Christian Johansen rethought how JavaScript testing could be integrated seamlessly into development workflows. Drawing from his expertise in front-end development and open source contributions, he presents a detailed guide on applying test-driven development (TDD) specifically to JavaScript projects. You learn how to build maintainable codebases by writing tests first, employing stubs and mocks effectively, and continuously refactoring for cleaner APIs and robust software. This book suits developers and QA professionals aiming to improve code quality and reduce bugs in complex JavaScript applications.

When Gio Lodi realized how underutilized test-driven development (TDD) was among Swift developers, he crafted this guide to bridge that gap. You’ll learn to write maintainable tests, manage expanding test suites, and leverage Swift's compiler feedback as a valuable part of your TDD workflow, illustrated by building a real iOS app across chapters. This book suits mid-level Swift developers eager to refine their coding discipline and those already testing but seeking deeper integration of TDD principles. It carefully balances practical coding examples with conceptual insights, helping you adopt a methodical approach to software craftsmanship in the Apple ecosystem.

When Daniel Irvine recognized that many developers struggle to integrate automated testing seamlessly with modern front-end frameworks, he wrote this book to bridge that gap specifically for Svelte developers. You’ll learn how to apply test-driven development techniques using tools like Vitest for unit testing and Playwright with Cucumber.js for end-to-end tests, with detailed examples covering component mocking, authentication, and refactoring. The book walks you through building a SvelteKit application from scratch, emphasizing maintainable and performant code that adapts as your app evolves. If you work with Svelte and want to make testing an integral part of your workflow, this book offers a focused, practical path without overwhelming you with unrelated details.

What if everything you knew about writing test-driven code in .NET was more complicated than necessary? Adam Tibi, drawing from over two decades of software consulting with major firms like Shell and Lloyds Bank, demystifies TDD by guiding you through building a real-world application using familiar tools such as xUnit, NSubstitute, and Entity Framework. You'll learn how to write loosely coupled, well-documented code by combining TDD with domain-driven design and SOLID principles, with practical chapters on managing mocking, dependency injection, and continuous integration.
