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
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

Was ist der Unterschied zwischen Blackbox-Testing und Whitebox-Testing in der Programmierung?
Blackbox-Testing bezieht sich auf eine Testmethode, bei der der Tester keine Kenntnisse über den internen Aufbau oder die Implementierung des Programms hat. Stattdessen werden nur die Ein- und Ausgabewerte getestet, um sicherzustellen, dass das Programm wie erwartet funktioniert. Whitebox-Testing hingegen bezieht sich auf eine Testmethode, bei der der Tester Kenntnisse über den internen Aufbau und die Implementierung des Programms hat. Dies ermöglicht es dem Tester, gezielt bestimmte Pfade und Bedingungen im Code zu testen, um mögliche Fehler zu finden.

Was ist der Unterschied zwischen CPU-Benchmarking und CPU-Stress-Testing?
CPU-Benchmarking ist ein Prozess, bei dem die Leistungsfähigkeit einer CPU anhand spezifischer Tests und Messungen bewertet wird. Es dient dazu, die Leistungsfähigkeit verschiedener CPUs zu vergleichen. CPU-Stress-Testing hingegen ist ein Prozess, bei dem die CPU unter extremen Bedingungen betrieben wird, um ihre Stabilität und Belastbarkeit zu testen. Es zielt darauf ab, die Grenzen der CPU auszuloten und mögliche Probleme wie Überhitzung oder Abstürze zu identifizieren.
