Cypress vs Jest: What are the differences?
What is Cypress? Better, faster, and more reliable testing for anything that runs in a browser. Cypress is a front end automated testing application created for the modern web. Cypress is built on a new architecture and runs in the same run-loop as the application being tested. As a result Cypress provides better, faster, and more reliable testing for anything that runs in a browser. Cypress works on any front-end framework or website.
Some of the features offered by Cypress are:
- Time Travel
- Automatic Waiting
On the other hand, Jest provides the following key features:
- Familiar Approach: Built on top of the Jasmine test framework, using familiar expect(value).toBe(other) assertions
- Mock by Default: Automatically mocks CommonJS modules returned by require(), making most existing code testable
- Short Feedback Loop: DOM APIs are mocked and tests run in parallel via a small node.js command line utility
