XCTest Playground
A playground-compatible implementation of XCTest macros for Test-Driven Development in Swift playgrounds.
Overview
XCTestPlayground provides a simple implementation of most XCTAssert macros designed specifically for use in Swift playgrounds. It enables developers to write and visualize test results directly within playgrounds, making it easier to practice Test-Driven Development (TDD) before moving code to Xcode projects.
Key Features
- Playground Integration — Uses playground's line-by-line execution display to show assert results visually.
- XCTestCase Mimicry — Includes a base class that runs methods prefixed with "test", mirroring XCTestCase behavior for seamless transition.
- Swift Version Support — Compatible with Swift 4 (Xcode 9) and offers a legacy Swift 2.2 version for older Xcode versions.
- Easy Setup — Can be added to any playground by simply copying a single Swift file to the Sources folder.
Philosophy
XCTestPlayground is built to streamline TDD workflows by allowing developers to write and test code interactively in playgrounds, reducing friction when transitioning to formal Xcode test suites.
