Fight!

Popularity

Jest has gained significant popularity in recent years and has become the de facto testing framework for JavaScript projects, especially in the React ecosystem. Jasmine, although still widely used, has a smaller community and is often used in projects that don't require the full-featured testing capabilities provided by Jest.

Ease of Use

Jest is known for its simplicity and ease of use. It has a zero-configuration setup, which means you can start writing tests without any additional configuration. Jasmine, on the other hand, requires some initial setup and configuration. Jest's API is more intuitive and beginner-friendly, making it easier for developers to write and maintain tests.

Features

Both packages provide similar features like test assertions, test runners, and mocking capabilities. However, Jest provides some additional features out of the box, such as snapshot testing and code coverage reporting. Jasmine requires additional libraries or plugins to achieve similar functionalities.

Integration with Frameworks

Jest is tightly integrated with React and has specific utilities for testing React components, making it the preferred choice for React projects. Jasmine, on the other hand, is a more general-purpose testing framework and can be used with various frameworks and libraries.

Performance

Jasmine tends to be faster in terms of test execution speed compared to Jest. Jest's additional features, like snapshot testing, can sometimes slow down test execution. However, the performance difference may not be significant for most projects.

Community and Ecosystem

Both Jest and Jasmine have active communities and extensive ecosystems with plugins and extensions. However, Jest has a larger and more active community due to its popularity, which results in better community support and more readily available resources and documentation.
