Test Driven Python Development. Develop high-quality and maintainable Python applications using the principles of test-driven development

Siddharta Govindaraj

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.

Test-Driven Development in Go. A practical guide to writing idiomatic and efficient Go tests through real-world examples

Adelina Simion

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.

Test-Driven Development. Podstawy

Rob Myers

Techniki i wskazówki tworzenia wysokiej jakości kodu, który jest łatwy w utrzymaniu. Sterowane testami tworzenie oprogramowania (TDD) to nie tylko sposób na testowanie kodu, ale całościowa metoda tworzenia oprogramowania: sposób myślenia o kodzie, sam proces pisania kodu oraz sposób ciągłej interakcji z kodem tworzonym przez zespół. Podręcznik Test-driven development prowadzi Czytelników przez proces pisania testów przed kodem, który daje gwarancję, że każda funkcja zostanie jasno zdefiniowana, dokładnie zweryfikowana i będzie gotowa do sprostania zmieniającym się potrzebom biznesowym. Książka ta pokazuje, jak TDD może zmienić proces tworzenia oprogramowania, ograniczając liczbę kosztownych błędów i umożliwiając zespołowi niezawodne dostarczanie wartości. Dzięki temu będzie mniej usterek i mniej troski o zakłócenie działania istniejących funkcji podczas wdrażania nowych. Programiści mogą śmiało przekształcać wewnętrzną strukturę kodu, aby dostosować go do nowych funkcji, i poświęcać mniej czasu na usuwanie błędów. Dzięki technikom i praktycznym przykładom zawartym w tej książce TDD staje się przystępne zarówno dla programistów, jak i menedżerów oraz właścicieli produktów. Dowiecie się, jak stworzyć sieć zabezpieczeń w postaci zautomatyzowanych testów, które chronią Waszą inwestycję, przyspieszają wdrażanie i umożliwiają śmiałe wprowadzanie innowacji - niezależnie od tego, czy korzystacie z istniejących systemów czy nowych technologii. Przyjmując podejście oparte na testach, zdobędziecie umiejętności potrzebne do tworzenia oprogramowania, które nie tylko jest niezawodne dzisiaj, ale także odporne na przyszłe zmiany. - Opanowanie podstawowego procesu TDD opartego na zasadzie "Red, Green, Refactor", aby tworzyć iteracyjnie oprogramowanie zorientowane na jakość. - Tworzenie i rozszerzanie zachowania na podstawie jasnych, możliwych do wykonania specyfikacji. - Projektowanie z uwzględnieniem wyjątkowych przypadków i warunków brzegowych, aby uniknąć kosztownych niespodzianek. - Utrzymywanie sprawnego i łatwego w utrzymaniu zestawu testów dzięki sprawdzonym, długoterminowym strategiom. - Wykorzystywanie dublerów testowych do izolowania zależności i zapewniania szybkości oraz precyzji testów. - Zastosowanie technik TDD w istniejących kodach źródłowych, dzięki czemu stare oprogramowanie stanie się łatwiejsze do testowania i bardziej niezawodne. - Zrozumienie korzyści biznesowych wynikających z pełnego wdrożenia TDD: mniej błędów, szybsze wprowadzanie nowych funkcji i większa elastyczność. - Poznanie sposobu, w jaki zasady TDD są stosowane w różnych językach programowania, środowiskach programistycznych i nowoczesnym tworzeniu sztucznej inteligencji opartej na agentach. Książka pozwala na wykonanie praktycznego kroku w kierunku zmniejszenia liczby błędów i płynniejszych wdrożeń, zgłębiając TDD we własnym tempie dzięki konkretnym przykładom i wskazówkom, które naprawdę przydadzą się w praktyce. Rob Myers to doświadczony programista i instruktor z ponad pięćdziesięcioletnim stażem. Szkolił i doradzał zespołom na całym świecie w zakresie TDD i praktyk Agile, pomagając organizacjom różnej wielkości osiągnąć trwałą doskonałość w tworzeniu oprogramowania.
