React testing made easy. Supports DOM and custom renderers.
Overview:
Rut is a cutting-edge React testing library designed to streamline the testing process while prioritizing performance and reliability. By abstracting the complexities of the react-test-renderer, Rut allows developers to focus on writing effective tests without getting bogged down in the technical details. It provides a clean, DOM-less environment that encourages best practices and reduces common pitfalls such as flakiness and code smells.
What sets Rut apart is its focus on maintaining type safety and supporting the evolving needs of modern testing with built-in asynchronous capabilities. With its easy-to-use framework, Rut aims to redefine how developers approach testing in React applications, making it a valuable tool for any team looking to enhance their testing strategy.
Features:
- Type Safe by Design: Test with confidence knowing that Rut prioritizes type safety, minimizing runtime errors.
- First-Class Async Support: Easily handle asynchronous calls, ensuring tests wait for the completion of actions before proceeding.
- Deep act() Integration: Leverage Rut’s powerful integration to manage updates and unmount components, simplifying logic verification.
- Mocked Synthetic Events: Dispatch DOM-level events using Rut’s synthetic event system, enhancing event testing and propagation.
- Pre-built Mocks: Increase test accuracy by utilizing pre-configured mocks tailored for a variety of common scenarios.
- Comprehensive Matchers: Take advantage of an array of built-in matchers for simple querying, making assertions straightforward and effective.
- Encouragement of Best Practices: Fosters the Arrange-Act-Assert testing pattern, leading to cleaner, more reliable tests that mimic user interaction.
- Broad Compatibility: Works seamlessly with React 16.9+ (Rut v1) and React 17+ (Rut v2), ensuring broad accessibility for developers.
