Testing The Composable Architecture (TCA) with TestStore

The Composable Architecture (TCA) from Point-Free is a Swift state management library for building apps in a Redux-style unidirectional data flow. One of TCA's selling points is testability: TestStore makes it straightforward to test state mutations, action sequences, and effects. TCA in 30 Seconds A TCA feature consists

Swift Unit Testing Guide: XCTest, Assertions, and Test Structure

Swift's built-in testing framework is XCTest, shipped with Xcode and available on all Apple platforms. Every Swift project created in Xcode includes an XCTest target by default. This guide covers how to write, organize, and run effective unit tests with XCTest. Project Setup When you create a new

Testing Swift Concurrency: async/await, Actors, and MainActor

Swift's structured concurrency model — async/await, actors, Task, and MainActor — requires specific testing patterns. The good news: Xcode 14+ makes async testing natural, and the actor model gives you clear isolation boundaries that map well to test setup. Async Test Methods Any XCTestCase method can be async (and

Swift

Swift Mocking with Protocols: Dependency Injection and Test Doubles

Swift doesn't have a reflection-based mocking framework like Java's Mockito — the language's static type system makes runtime proxy generation impractical. Instead, Swift mocking relies on protocols and dependency injection. The approach is more explicit but also more type-safe and faster at runtime. The Foundation:

BDD Testing in Swift with Quick and Nimble

Quick and Nimble are the most popular BDD testing libraries for Swift. Quick provides a describe/it DSL for organizing tests; Nimble provides expressive matchers. Together they make test intent clearer than raw XCTest and scale better for complex domain logic. Installation Swift Package Manager // Package.swift or Xcode Package

iOS UI Testing with XCUITest: Element Queries, Gestures, and CI

XCUITest is Apple's framework for automating iOS UI interactions. Tests launch the app in a simulator or on a real device, interact with it like a user would, and assert on what appears on screen. Unlike unit tests, UI tests can catch integration issues — broken navigation, missing screens,

XCTest and XCUITest: iOS Testing with Swift and Xcode

Apple's built-in testing framework is XCTest. It handles both unit tests and UI tests — and since Xcode 15, the tooling around it has never been better. If you're developing native iOS apps in Swift, XCTest is the place to start. This guide covers unit testing with
