Jest vs SuperTest: What are the differences?

What is Jest? Painless JavaScript Unit Testing. Jest provides you with multiple layers on top of Jasmine.

What is SuperTest? *A library for testing node.js HTTP servers *. It is a super-agent driven library for testing node.js HTTP servers using a fluent API. It provides a high-level abstraction for testing HTTP, while still allowing you to drop down to the lower-level API provided by superagent.

Jest and SuperTest belong to "Javascript Testing Framework" category of the tech stack.

Some of the features offered by Jest are:

  • 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

On the other hand, SuperTest provides the following key features:

  • HTTP assertions
  • Asynchronous
  • Promise support

Jest and SuperTest are both open source tools. Jest with 26.9K GitHub stars and 3.66K forks on GitHub appears to be more popular than SuperTest with 8.8K GitHub stars and 568 GitHub forks.

According to the StackShare community, Jest has a broader approval, being mentioned in 398 company stacks & 725 developers stacks; compared to SuperTest, which is listed in 6 company stacks and 7 developer stacks.

As we all know testing is an important part of any application. To assist with our testing we are going to use both Cypress and Jest. We feel these tools complement each other and will help us get good coverage of our code. We will use Cypress for our end to end testing as we've found it quite user friendly. Jest will be used for our unit tests because we've seen how many larger companies use it with great success.

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.

        What are some alternatives to Jest and SuperTest?
        Mocha
        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.
        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.
        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.
        Enzyme
        Enzyme is a JavaScript Testing utility for React that makes it easier to assert, manipulate, and traverse your React Components' output.
        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.
