This book starts with a look at the test-driven development process, and how it is different from the traditional way of writing code. All the concepts are presented in the context of a real application that is developed in a step-by-step manner over the course of the book. While exploring the common types of smelly code, we will go back into our example project and clean up the smells that we find.Additionally, we will use mocking to implement the parts of our example project that depend on other systems. Towards the end of the book, we'll take a look at the most common patterns and anti-patterns associated with test-driven development, including integration of test results into the development process.

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.

Spośród wielu koncepcji tworzenia oprogramowania na szczególną uwagę zasługuje model programowania sterowanego testami - TDD. Zastosowanie podejścia TDD ułatwia utrzymanie wysokiej jakości kodu. Technika ta opiera się na dodawaniu funkcjonalności do produktu dopiero po utworzeniu i przeprowadzeniu testów jednostkowych. TDD coraz częściej jest wyborem szanowanych firm programistycznych. W tej praktycznej książce przedstawiono zasady TDD na rzeczywistych przykładach z użyciem popularnych frameworków, takich jak ASP.NET Core i Entity Framework. Po zapoznaniu się z solidnym wprowadzeniem do koncepcji TDD dowiesz się, jak można używać Visual Studio 2022 do tworzenia aplikacji internetowej z wykorzystaniem Entity Framework, a także baz danych SQL Server i Cosmos DB. Nauczysz się też korzystać z różnych wzorców, takich jak repozytorium, usługi i budowniczy. Ponadto omówiono tu architekturę DDD i inne najlepsze praktyki stosowane podczas tworzenia oprogramowania, w tym reguły SOLID i wskazówki FIRSTHAND. Nie zabrakło przydatnych uwag o biznesowych aspektach podejścia TDD. W książce między innymi: testy jednostkowe i mechanizm wstrzykiwania zależności NSubstitute: imitacje i dublery używane podczas testów zastosowanie TDD dla ASP.NET API, Entity Framework i baz danych tworzenie potoków ciągłej integracji za pomocą GitHub zaawansowane scenariusze używania imitacji korzyści z wdrażania podejścia TDD przez zespoły i firmy TDD wprowadza dobre praktyki i doskonali programistę!

Test-Driven Development with C++. A simple guide to writing bug-free Agile code
Abdul Wahid Tanner
Modern, standard C++ is all that is needed to create a small and practical testing framework that will improve the design of any project. This allows you to think about how the code will be used, which is the first step in designing intuitive interfaces. TDD is a modern balanced software development approach that helps to create maintainable applications, provide modularity in design, and write minimal code that drastically reduces defects. With the help of this book, you'll be able to continue adding value when designs need to change by ensuring that the changes don't break existing tests.In this book, you will use test-driven development (TDD) to gain practical skills by writing a simple testing framework and then using it to drive the design of a logging library. The book will help you enhance your software development skills with test cases. You'll understand how to design and implement test cases. The chapters will also show you how to utilize the TDD approach to be more productive in software development than attempting to code in large unstructured steps.By the end of this book, you'll have gained knowledge of TDD and testing and also built a working logging library with unique features not found in other libraries.

PHP web developers end up building complex enterprise projects without prior experience in test-driven and behavior-driven development which results in software that’s complex and difficult to maintain. This step-by-step guide helps you manage the complexities of large-scale web applications. It takes you through the processes of working on a project, starting from understanding business requirements and translating them into actual maintainable software, to automated deployments.You’ll learn how to break down business requirements into workable and actionable lists using Jira. Using those organized lists of business requirements, you’ll understand how to implement behavior-driven development (BDD) and test-driven development (TDD) to start writing maintainable PHP code. You’ll explore how to use the automated tests to help you stop introducing regressions to an application each time you release code by using continuous integration.By the end of this book, you’ll have learned how to start a PHP project, break down the requirements, build test scenarios and automated tests, and write more testable and maintainable PHP code. By learning these processes, you’ll be able to develop more maintainable, and reliable enterprise PHP applications.
Test-Driven Java Development. Invoke TDD principles for end-to-end application development with Java
Viktor Farcic, Alex Garcia
Test-driven development (TDD) is a development approach that relies on a test-first procedure that emphasises writing a test before writing the necessary code, and then refactoring the code to optimize it.The value of performing TDD with Java, one of the most established programming languages, is to improve the productivity of programmers, the maintainability and performance of code, and develop a deeper understanding of the language and how to employ it effectively.Starting with the basics of TDD and reasons why its adoption is beneficial, this book will take you from the first steps of TDD with Java until you are confident enough to embrace the practice in your day-to-day routine.You’ll be guided through setting up tools, frameworks, and the environment you need, and will dive right in to hands-on exercises with the goal of mastering one practice, tool, or framework at a time. You’ll learn about the Red-Green-Refactor procedure, how to write unit tests, and how to use them as executable documentation.With this book you’ll also discover how to design simple and easily maintainable code, work with mocks, utilise behaviour-driven development, refactor old legacy code, and release a half-finished feature to production with feature toggles.You will finish this book with a deep understanding of the test-driven development methodology and the confidence to apply it to application programming with Java.

Initially, all processing used to happen on the server-side and simple output was the response to web browsers. Nowadays, there are so many JavaScript frameworks and libraries created that help readers to create charts, animations, simulations, and so on. By the time a project finishes or reaches a stable state, so much JavaScript code has already been written that changing and maintaining it further is tedious. Here comes the importance of automated testing and more specifically, developing all that code in a test-driven environment. Test-driven development is a methodology that makes testing the central part of the design process – before writing code developers decide upon the conditions that code must meet to pass a test. The end goal is to help the readers understand the importance and process of using TDD as a part of development.This book starts with the details about test-driven development, its importance, need, and benefits. Later the book introduces popular tools and frameworks like YUI, Karma, QUnit, DalekJS, JsUnit and goes on to utilize Jasmine, Mocha, Karma for advanced concepts like feature detection, server-side testing, and patterns. We are going to understand, write, and run tests, and further debug our programs. The book concludes with best practices in JavaScript testing. By the end of the book, the readers will know why they should test, how to do it most efficiently, and will have a number of versatile tests (and methods for devising new tests) to get to work immediately.
