MirrorDiffKit
A Swift library that provides human-readable diff output for XCTAssertEqual failures and default Equatable implementations.
What is MirrorDiffKit?
MirrorDiffKit is a Swift library designed to improve the testing experience by generating human-readable diff outputs when XCTAssertEqual assertions fail. It solves the problem of cryptic and unhelpful test failure messages by clearly showing what changed between two values. The library also provides default Equatable implementations for comparing types that don't conform to Equatable.
Swift developers who write unit tests with XCTest and want clearer failure messages, particularly those working with complex data structures or custom types.
Developers choose MirrorDiffKit because it dramatically reduces debugging time by presenting test failures in an intuitive diff format, and it works with any Swift type without requiring Equatable conformance.
Overview
Graduation from messy XCTAssertEqual messages.

Best For
