Tyrtle vs Vitest comparison of testing frameworks
What are the differences between Tyrtle and Vitest?

Unit Testing

Unit testing, integration testing, and component testing

Tyrtle is a Javascript unit testing framework that emphasises simplicity, cleanliness and expressiveness.

Tyrtle runs either in the browser or on NodeJS. In a CommonJS environment (eg: Node, or the browser running RequireJS), nothing is added to the global space, and with plain Javascript in the browser, only one variable is added to the window object. This keeps it clean and ensures that it won't interfere with your codebase.

Vitest is a fast, modern JavaScript test runner built on Vite

It supports unit, integration, and component testing with a Jest-compatible API, built-in mocking, and TypeScript support. Designed for speed and efficiency. It seamlessly integrates with Vite projects but can also be used independently.

N/A

No

Vitest does not natively follow the xUnit test structure, but it supports similar concepts. It uses a Jest-compatible API, meaning it provides test lifecycle hooks (beforeEach, afterEach, etc.) and assertions similar to xUnit-style frameworks. However, it does not strictly adhere to classical xUnit architecture, such as NUnit, JUnit, or MSTest.

Yes

Front-end pieces of code can be tested, you can test various components and functionality

Yes

Vitest uses JSDOM to simulate a browser environment, making it easy to test DOM-related functionality. It has Browser Mode for running component tests in the browser. Vitest can run tests in real browsers via tools like Playwright or WebdriverIO.

Yes

Back-end components and functions can be tested using tyrtle

Yes

Vitest supports server-side testing, allowing you to test Node.js and server-side logic such as APIs, databases, and backend functions. It provides native support for ESM, mocks, spies, and environment configurations.

N/A

Yes

Vitest's Test Context, inspired by Playwright Fixtures, allows defining utils, states, and fixtures for use in tests. It enables sharing context between tests using the test.context object and supports tuple syntax for fixtures, allowing customization of fixture options per test.

N/A

Yes

Vitest supports group fixtures by using describe blocks with beforeAll, beforeEach, afterEach, and afterAll hooks. These hooks allow setting up a shared state for a group of tests.

N/A

No

GNU GPL

MIT License

Yes

By using Myrtle, a sister project of Tyrtle which provides various Mocking features such as: -Mocking (spying and stubbing functions); -Mock function generation; -Timer manipulation-Speed profiling

Yes

Vitest has built-in support for mocks, allowing you to mock functions, modules, timers, and spies similar to Jest.

N/A

Yes

Vitest supports Grouping, allowing you to organize tests into groups using describe() blocks.

Vitest provides a watch mode for instant test re-runs, ESM-first architecture for modern development, parallel and concurrent test execution for speed, custom reporters for CI/CD integration, and fake timers for testing time-dependent code.
