Discover what tools there are for unit testing in iOS, and how to work in a test-driven environment. This book reveals how testing is a crucial capability in any iOS developer''s toolset, and a minimum requirement in iOS interviews. A few years ago, tests on mobile platforms were not very popular. It wasn''t a technical constraint, more a cultural one. But these days it''s a crucial skill set, especially when projects become big and hard to maintain. This book shows you how to set up a testing target in XCode unit tests. You''ll learn how to write unit tests properly and incorporate concepts like spies and mocks and code coverage. You''ll also learn the philosophy behind the architecture of UI tests, and how to mock network and DB layers in testing. Write unbreakable UI tests performance tests, as well. And learn the difference between integration tests and snapshot testing. This book will show you how to maintain code that''s not only bug-free but will also remain high quality over time and maintainable while you make changes and refactors during an app''s life. Testing in all its aspects is the best way of maintaining iOS projects to run fast and reliably long after you''ve released them. Many iOS developers working today lack an understanding of the advantages of testing, and might be unfamiliar with tools that make the job easier, such as XCTest framework. With Pro iOS Testing you''ll see how to develop and test apps that work and stay working for a long time. What You''ll Learn - Set up a stable testing system - Extend an app''s lifetime with testing before release - Incorporate testing into your everyday development routine - Write unbreakable UI tests performance tests - Understand the difference between integration tests and snapshot testing Who This Book Is For Professional iOS developers with extensive experience in the basics of building apps.

Build Your Own Test Framework - Daniel Irvine - Bog - APress - Plusbog.dk

Build Your Own Test Framework - Daniel Irvine - Bog - APress - Plusbog.dk

Learn to write better automated tests that will dramatically increase your productivity and have fun while doing so. This book is a build-your-own adventure designed for individual reading and for collaborative workshops. You will build an xUnit automated test framework using JavaScript: initially a clone of Jest, but adding a couple of neat features borrowed from RSpec, the genre-defining tool for behavior-driven development (BDD). Along the way, you will explore the philosophy behind automated testing best practices. The automated test runner is one of the most important innovations within software engineering. But for many programmers, automated testing remains a mystery, and knowing how to write good tests is akin to sorcery. As the chapters of this book unfold, you will see how the humble test runner is an elegant and simple piece of software. Each chapter picks a single feature to build, like the "it" function or the "beforeEach" block. It picks apart the theory of why the feature needs to exist, and how to use it effectively in your own test suites. Every chapter ends with a set of ideas for extension points should you wish to explore further, alone or in groups. The book culminates in an implementation of test doubles and mocks-one of the most difficult and misunderstood concepts within automated testing. By the end of the book, you will have gained a solid understanding of automated testing principles that you can immediately apply to your work projects. What You''ll Learn - Build an xUnit automated test framework - See how an automated test runner works - Understand the best practices for automated unit testing - Effectively use test doubles and mocks Who This Book Is For Software developers with JavaScript experience who are seeking to master the art of automated testing.

Modern Software Testing Techniques - Attila Kovacs - Bog - APress - Plusbog.dk

Modern Software Testing Techniques - Attila Kovacs - Bog - APress - Plusbog.dk

Many books have been written about software testing, but most of them discuss the general framework of testing from a traditional perspective. Unfortunately, traditional test design techniques are often ineffective and unreliable for revealing the various kinds of faults that may occur. This book introduces three new software testing techniques: Two-Phase Model-Based Testing, the Action-State Testing, and the General Predicate Testing, all of which work best when applied with efficient fault revealing capabilities. You’ll start with a short recap of software testing, focusing on why risk analysis is obligatory, how to classify bugs practically, and how fault-based testing can be used for improving test design. You’ll then see how action-state testing merges the benefits of state transition testing and use case testing into a unified approach. Moving on you’ll look at general predicate testing and how it serves as an extension of boundary value analysis, encompassing morecomplex predicates. Two-phase model-based testing represents an advanced approach where the model does not necessarily need to be machine-readable; human readability suffices. The first phase involves a high-level model from which abstract tests are generated. Upon manual execution of these tests, the test code is generated. Rather than calculating output values, they are merely checked for conformity. The last part of this book contains a chapter on how developers and testers can help each other and work as a collaborative team. What You'll LearnApply efficient test design techniques for detecting domain faultsWork with modeling techniques that combine all the advantages of state transition testing and uses case testingGrasp the two-phase model-based testing technique Use test design efficiently to find almost all the bugs in an applicationWho This Book Is ForSoftware developers, QA engineers, and, business analysts

Patterns in the Machine - Wayne T. Taylor - Bog - APress - Plusbog.dk

Patterns in the Machine - Wayne T. Taylor - Bog - APress - Plusbog.dk

Discover how to apply software engineering patterns to develop more robust firmware faster than traditional embedded development approaches. In the authors'' experience, traditional embedded software projects tend towards monolithic applications that are optimized for their target hardware platforms. This leads to software that is fragile in terms of extensibility and difficult to test without fully integrated software and hardware. Patterns in the Machine focuses on creating loosely coupled implementations that embrace both change and testability. This book illustrates how implementing continuous integration, automated unit testing, platform-independent code, and other best practices that are not typically implemented in the embedded systems world is not just feasible but also practical for today''s embedded projects. After reading this book, you will have a better idea of how to structure your embedded software projects. You will recognize that while writing unit tests, creating simulators, and implementing continuous integration requires time and effort up front, you will be amply rewarded at the end of the project in terms of quality, adaptability, and maintainability of your code. What You Will Learn - Incorporate automated unit testing into an embedded project - Design and build functional simulators for an embedded project - Write production-quality software when hardware is not available - Use the Data Model architectural pattern to create a highly decoupled design and implementation - Understand the importance of defining the software architecture before implementation starts and how to do it - Discover why documentation is essential for an embedded project - Use finite state machines in embedded projects Who This Book Is For Mid-level or higher embedded systems (firmware) developers, technical leads, software architects, and development managers.
