iOS Code Testing: Test-Driven Development and Behavior-Driven Development with Swift

Put into motion practical examples to master Test-Driven Development (TDD) and acceptance testing in Swift.

This book uses a pragmatic approach to writing well-tested code and provides techniques that can be used to retrofit tests to legacy code bases. You’ll be introduced to basic principles of TDD, such as Test First, Red-Green-Refactor, Remove Duplicate code, Dependency Injection, and Single Responsibility. Approaches covered include TDD, behavior-driven development (BDD), UI, and acceptance testing with common standard/open source frameworks.

iOS Code Testing offers helpful instruction to teach iOS developers to retrospectively fit tests to legacy code, refactor legacy code so as to make the code more testable, install and configure a popular Swift BDD framework, practice BDD with Xcode, and create automated UI tests with Xcode. Additionally, many projects have legacy code bases. Legacy code is often seen as a blocker when it comes to implementing any kind of testing.

What You Will Learn

• Fit test to legacy code retrospectively
• Install and configure popular Swift BDD frameworks
• Practice BDD with Xcode
