  • Quality Code: Software Testing Principles, Practices, and Patterns
    Quality Code: Software Testing Principles, Practices, and Patterns

    Test-driven, test-first, and test-early development practices are helping thousands of software development organizations improve their software. Now, in Quality Code: Software Testing Principles, Practices, and Patterns, Stephen Vance builds on all that’s been learned about test-driven development, helping you achieve unprecedented levels of first-time quality. Using real-world code examples, this guide introduces patterns, principles, and more than two dozen detailed techniques for testing any software system more fully, effectively, and painlessly. Vance presents a conceptual framework to help you focus your efforts and design recommendations for improving testability across the software lifecycle, and also provides hands-on guidance to simplify testing of the full spectrum of code constructs. You’ll learn how to choose the best testing techniques for every situation, from the most common scenarios to threading. Two complete case studies put it all together, walking you through testing a brand-new Java application and an untested “legacy” JavaScript jQuery plugin. Whether you’re developing cutting-edge code for a new start-up, or maintaining an unruly old system, this guide will help you deliver exactly what you need: quality code.   • Simplify unit testing of all your code—and improve integration and system testing • Delineate intent and implementation to promote more reliable and scalable testing • Overcome confusion and misunderstandings about the mechanics of writing tests • Test “side effects,” behavioral characteristics, and contextual constraints • Understand subtle interactions between design and testability—and make them work for, not against, you • Discover core principles that guide your key testing decisions • Explore testing getters/setters, string handling, encapsulation, override variations, visibility, singleton patterns, error conditions, and more • Reproduce and test complex race conditions deterministically

  • Effective Software Testing
    Effective Software Testing

    Effective Software Testing is a hands-on guide to creating high quality tests, from your first line of code through pre-delivery checks. It's full of techniques drawn from proven research in software engineering. You'll learn to efficiently engineer tests specifically for your software and end reliance on generic testing practices that may be right for every project. Each chapter puts a new technique into practice with source code samples, real-world tradeoffs, and answers to the common questions developers pose about testing. You'll learn how to scrutinize your requirements for potential tests, generate tests from your code structure, and engineer rigorous suites of unit, integration, and system tests.Go beyond unit tests! Great software testing makes the entire development process more efficient, from understanding your code before you write it to catching bugs in tricky corner cases.Effective Software Testing teaches you a systematic approach to software testing. You'll master easy-to-apply techniques to create strong test suites that are specifically engineered for your code. Following real-world use cases and detailed code samples, you'll soon be engineering tests that find the bugs hiding in edge cases and the parts of code you would never think of testing! Along the way, you'll develop an intuition for testing that can save years of learning by trial and error.

  • Developer Testing: Building Quality into Software
    Developer Testing: Building Quality into Software

    How do successful agile teams deliver bug-free, maintainable software—iteration after iteration? The answer is: By seamlessly combining development and testing. On such teams, the developers write testable code that enables them to verify it using various types of automated tests. This approach keeps regressions at bay and prevents “testing crunches”—which otherwise may occur near the end of an iteration—from ever happening. Writing testable code, however, is often difficult, because it requires knowledge and skills that cut across multiple disciplines.   In Developer Testing, leading test expert and mentor Alexander Tarlinder presents concise, focused guidance for making new and legacy code far more testable. Tarlinder helps you answer questions like: When have I tested this enough? How many tests do I need to write? What should my tests verify? You’ll learn how to design for testability and utilize techniques like refactoring, dependency breaking, unit testing, data-driven testing, and test-driven development to achieve the highest possible confidence in your software. Through practical examples in Java, C#, Groovy, and Ruby, you’ll discover what works—and what doesn’t.   You can quickly begin using Tarlinder’s technology-agnostic insights with most languages and toolsets while not getting buried in specialist details. The author helps you adapt your current programming style for testability, make a testing mindset “second nature,” improve your code, and enrich your day-to-day experience as a software professional. With this guide, you will Understand the discipline and vocabulary of testing from the developer’s standpointBase developer tests on well-established testing techniques and best practicesRecognize code constructs that impact testabilityEffectively name, organize, and execute unit testsMaster the essentials of classic and “mockist-style” TDDLeverage test doubles with or without mocking frameworksCapture the benefits of programming by contract, even without runtime support for contractsTake control of dependencies between classes, components, layers, and tiersHandle combinatorial explosions of test cases, or scenarios requiring many similar testsManage code duplication when it can’t be eliminatedActively maintain and improve your test suitesPerform more advanced tests at the integration, system, and end-to-end levelsDevelop an understanding for how the organizational context influences quality assuranceEstablish well-balanced and effective testing strategies suitable for agile teams

  • Wie kann man verschiedene Code-Snippets in einer Software integrieren, um die Effizienz der Programmierung zu steigern?

    Man kann verschiedene Code-Snippets in einer Software integrieren, indem man sie in Bibliotheken oder Modulen organisiert und sie dann in verschiedenen Teilen des Programms wiederverwendet. Dadurch wird die Entwicklungszeit verkürzt und die Fehleranfälligkeit reduziert. Außerdem können Entwickler durch die Verwendung von Code-Snippets auf bewährte Lösungen zurückgreifen und so die Effizienz der Programmierung steigern.

  • Wie kann das Konzept der objektorientierten Programmierung in verschiedenen Programmiersprachen angewendet werden, um die Wiederverwendbarkeit von Code zu verbessern und die Entwicklung von Software zu erleichtern?

    Das Konzept der objektorientierten Programmierung kann in verschiedenen Programmiersprachen angewendet werden, indem Klassen und Objekte erstellt werden, die es ermöglichen, Code zu organisieren und zu strukturieren. Durch Vererbung können Klassen von anderen Klassen erben, wodurch Code wiederverwendet und die Entwicklung beschleunigt werden kann. Polymorphismus ermöglicht es, dass verschiedene Klassen auf einheitliche Weise verwendet werden können, was die Flexibilität und Wiederverwendbarkeit des Codes erhöht. Durch die Verwendung von Schnittstellen können Klassen definiert werden, die bestimmte Methoden implementieren müssen, was die Interoperabilität und Wiederverwendbarkeit von Code verbessert.
