Cypress vs Jasmine vs Jest: What are the differences?

Introduction:
Key differences between Cypress, Jasmine, and Jest are outlined below.

1. **Testing Framework Integration**: Cypress is a comprehensive end-to-end testing framework, while Jasmine and Jest are primarily unit testing frameworks.
2. **Syntax**: Cypress uses a custom syntax that is more minimalistic and easy to read, whereas Jasmine and Jest use more traditional JavaScript testing syntax.
3. **Built-in Spies/Stubs/Mocks**: Jest comes with built-in support for spies, stubs, and mocks, making it easier to mock dependencies compared to Cypress and Jasmine.
4. **Browser Support**: Cypress runs tests directly in the browser, providing real-time feedback, while Jasmine and Jest run tests in Node.js environment, making browser-specific testing more challenging.
5. **Performance**: Cypress executes tests in a real browser, resulting in slower test runs, while Jasmine and Jest run tests in a simulated environment, leading to faster performance.
6. **Community Support**: Jest has a larger community and ecosystem due to being maintained by Facebook, providing more resources and support compared to Cypress and Jasmine.

In Summary, the key differences between Cypress, Jasmine, and Jest lie in their testing framework integration, syntax, support for mocks, browser environment, performance, and community support.

What is Cypress?

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.

What is Jasmine?

Jasmine is a Behavior Driven Development testing framework for JavaScript. It does not rely on browsers, DOM, or any JavaScript framework. Thus it's suited for websites, Node.js projects, or anywhere that JavaScript can run.

What is Jest?

Jest provides you with multiple layers on top of Jasmine.

What are some alternatives to Cypress, Jasmine, and Jest?
Selenium
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.
TestCafe
It is a pure node.js end-to-end solution for testing web apps. It takes care of all the stages: starting browsers, running tests, gathering test results and generating reports.
Puppeteer
Puppeteer is a Node library which provides a high-level API to control headless Chrome over the DevTools Protocol. It can also be configured to use full (non-headless) Chrome.
WebdriverIO
WebdriverIO lets you control a browser or a mobile application with just a few lines of code. Your test code will look simple, concise and easy to read.
Protractor
Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would.
