Writing tests improves the design of your apps, as it pushes you to have a more modularized design. This in turn improves the maintainability and sustainability of your apps. This book is for iOS developers who already know the basics of iOS and Swift development but want to learn all the testing pro features in iOS. You'll start by reviewing the TDD Cycle and how to implement these concepts on a legacy project or a new one. You'll then walk through TDD step-by-step on a blank project, including setting up test targets, assertions, and expectations. You'll follow that with all levels of testing such as unit tests, integration tests, and end-to-end tests, and also tackle fairly complex, yet badly written legacy code. The book will take you through the journey of modularizing a legacy app using TDD. Throughout this journey, you will be introduced to multiple testing concepts and techniques, like writing tests for network and core data layers. You will write tests to ensure the thread safety of your app. And you'll add a new feature while you are in the middle of refactoring, which is an important skill so you can keep adding features while you are fixing your technical debt. By the end of this book, you will have all the tools needed to become a testing master. What You'll Learn Use mocking and dependency injection to make components more testable Write tests for asynchronous code like network code Add new features to existing legacy apps using TDD Who This Book Is For Experienced iOS developers who care about software quality and meeting customer expectations. 606 $aProgramari d'aplicació$xDesenvolupament$2lemac 606 $aProgramari$xProves$2lemac 606 $aComputer software$xTesting 606 $aApplication software$xDevelopment 615 7$aProgramari d'aplicació$xDesenvolupament 615 7$aProgramari$xProves 615 0$aComputer software$xTesting. 615 0$aApplication software$xDevelopment. 676 $a005.14 700 $aEl-Morabea$b Khaled$01072833 702 $aEl-Garem$b Hassaan 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910506385303321 996 $aModularizing Legacy Projects Using TDD$92569046 997 $aUNINA
