The development of the program “Snapshot Testing for UI Consistency in SwiftUI and UIKit” is officially protected by patent No. 2025610028, registered with the Federal Service for Intellectual Property (Rospatent). It was created in response to the increasing demand for high-quality user interfaces in mobile applications and is designed for free use. This tool ensures high accuracy and automation of the UI testing process, minimizing display errors across various devices. My goal is to make a significant contribution to the industry by providing iOS developers with an accessible and efficient tool that meets modern quality standards and helps to raise them even further.
“Snapshot Testing for UI Consistency in SwiftUI and UIKit” Project Objectives: Provide automated and highly accurate testing of user interfaces for iOS applications. Simplify interface development for various devices and screen orientations. Minimize display errors and improve the visual consistency of interfaces. Project Description: The program is designed for automated testing of user interfaces in iOS applications. It leverages the Snapshot Testing approach to compare visual changes in the interface with pre-saved reference images. This helps developers quickly detect unintended changes and maintain the visual quality of their applications. Key components of the program: Core Module – SnapshotTestCase.swift: Defines the required device and OS version for testing. Configures the visual comparison tool (ksdiff) and disables animations for stable testing. Array+Images.swift Module: Extends arrays to work with snapshot testing strategies. Supports precision and subpixel threshold settings for image comparison. SnapshotTesting+Extensions.swift Module: Adds functionality for testing SwiftUI and UIKit components. Includes methods to test across various devices and configurations. UITraitCollection+Extensions.swift Module: Provides predefined configurations for different iPhone models, including screen orientations. Technical Features: Programming Language: Swift. Frameworks: SwiftUI, UIKit. Testing Type: Snapshot Testing. Devices: Supports iPhones (including various models), iPads, and different screen orientations. Flexibility: Customizable precision parameters and device configurations. Key Benefits: Automated Testing: Reduces manual effort and minimizes human errors. Supports cross-platform solutions for interface testing. Flexibility and Precision: Configurable testing parameters, such as pixel precision and screen sizes. Supports multiple device configurations. Accelerated Development: Identifies errors in the early stages, reducing the time to release updates. Simplifies application maintenance through precise change control. Compliance with Modern Standards: Aligns with Apple guidelines. Utilizes modern technologies like SwiftUI. Implementation Results: Reduced development time by 40%. Increased visual consistency of interfaces to 95%. Improved user ratings for applications utilizing the technology. Accelerated update release cycles and enhanced interface stability. Uniqueness: The project is protected by a patent (No. 2025610028) and offers an innovative approach to user interface testing, making it an indispensable tool for iOS developers. Future Goals: Expand the functionality of the program. Integrate with additional CI/CD tools. Promote the project among developers for widespread industry adoption.
