Enzyme vs Jasmine vs Mocha: What are the differences?

  1. Testing Framework: Enzyme is specifically designed to test React components and their internal state and behavior, while Jasmine and Mocha are general-purpose testing frameworks used for testing various types of JavaScript applications and code.

  2. API Design: Enzyme provides a more intuitive and easy-to-use API tailored for React components, offering methods like shallow, mount, and find for testing. In contrast, Jasmine and Mocha have different APIs that require additional setup and configuration for testing React components.

  3. Snapshot Testing: Enzyme seamlessly integrates with tools like Jest to support snapshot testing for React components, helping in capturing the expected output and easily detecting any changes. Jasmine and Mocha have limited support for snapshot testing and may require additional plugins or configurations.

  4. Virtual DOM Handling: Enzyme utilizes a virtual DOM to render React components in memory during tests, providing a lightweight and efficient way to simulate component behavior. Jasmine and Mocha lack built-in support for virtual DOM handling, which can make testing React components more complex and time-consuming.

  5. Component Testing Focus: Enzyme emphasizes testing the internal state, props, and rendering of React components to ensure their proper functionality and behavior, making it a preferred choice for React developers. Jasmine and Mocha, being more generic, may require additional setup and customizations to effectively test React components.

  6. Community Support: Enzyme has a strong community backing and extensive documentation focused on React component testing, making it easier for developers to find resources, examples, and solutions to common testing scenarios. Jasmine and Mocha, while popular in the JavaScript testing community, may not have the same level of specific support for React component testing.

In Summary, Enzyme is a specialized testing framework tailored for React components, offering a more intuitive API, snapshot testing integration, virtual DOM handling, component-focused testing, and strong community support compared to general-purpose frameworks like Jasmine and Mocha.

Advice on Jasmine, Mocha, Enzyme

Decided

We use Mocha for our FDA verification testing. It's integrated into Meteor, our upstream web application framework. We like how battle tested it is, its' syntax, its' options of reporters, and countless other features. Most everybody can agree on mocha, and that gets us half-way through our FDA verification and validation (V&V) testing strategy.

Needs advice

Postman will be used to do integration testing with the backend API we create. It offers a clean interface to create many requests, and you can even organize these requests into collections. It helps to test the backend API first to make sure it's working before using it in the front-end. Jest can also be used for testing and is already embedded into React. Not only does it offer unit testing support in javascript, it can also do snapshot testing for the front-end to make sure components are rendering correctly. Enzyme is complementary to Jest and offers more functions such as shallow rendering. UnitTest will be used for Python testing as it is simple, has a lot of functionality and already built in with python. Sentry will be used for keeping track of errors as it is also easily integratable with Heroku because they offer it as an add-on. LogDNA will be used for tracking logs which are not errors and is also a Heroku add-on. Its good to have a separate service to record logs, monitor, track and even fix errors in real-time so our application can run more smoothly.

Detailed Comparison

Jasmine
Jasmine
Mocha
Mocha
Enzyme
Enzyme

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.

Mocha is a feature-rich JavaScript test framework running on node.js and the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases.

Enzyme is a JavaScript Testing utility for React that makes it easier to assert, manipulate, and traverse your React Components' output.

What are some alternatives to Jasmine, Mocha, Enzyme?

Jest

Jest

Jest provides you with multiple layers on top of Jasmine.

Cypress

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.

CodeceptJS

CodeceptJS

It is a modern end to end testing framework with a special BDD-style syntax. The test is written as a linear scenario of user's action on a site. Each test is described inside a Scenario function with I object passed into it.

Protractor

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.

AVA

AVA

Even though JavaScript is single-threaded, IO in Node.js can happen in parallel due to its async nature. AVA takes advantage of this and runs your tests concurrently, which is especially beneficial for IO heavy tests. In addition, test files are run in parallel as separate processes, giving you even better performance and an isolated environment for each test file.

Ghost Inspector

Ghost Inspector

It lets you create and manage UI tests that check specific functionality in your website or application. We execute these automated browser tests continuously from the cloud and alert you if anything breaks.

QUnit

QUnit

QUnit is a powerful, easy-to-use JavaScript unit testing framework. It's used by the jQuery, jQuery UI and jQuery Mobile projects and is capable of testing any generic JavaScript code, including itself!

Sorry-cypress

Sorry-cypress

Open-source, self-hosted alternative Cypress Dashboard.

Baretest

Baretest

It is a fast and simple JavaScript test runner. It offers near-instant performance and a brainless API. It makes testing tolerable.

SinonJS

SinonJS

It is a really helpful library when you want to unit test your code. It supports spies, stubs, and mocks. The library has cross browser support and also can run on the server using Node.js.
