Jest vs CodeceptJS: What are the differences?

Jest: Painless JavaScript Unit Testing. Jest provides you with multiple layers on top of Jasmine; CodeceptJS: Modern End 2 End Testing Framework for NodeJS. 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.

Jest and CodeceptJS can be primarily classified as "Javascript Testing Framework" tools.

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, CodeceptJS provides the following key features:

  • Behavior Driven Development
  • Acceptance Testing
  • Data Driven Tests

Jest and CodeceptJS are both open source tools. It seems that Jest with 26.9K GitHub stars and 3.68K forks on GitHub has more adoption than CodeceptJS with 2.33K GitHub stars and 401 GitHub forks.

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 CodeceptJS and Jest?
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.
Codeception
Full-stack testing framework for PHP. Run browsers tests, framework tests, APIs tests, unit tests with ease.
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.
BrowserStack
Live, Web-Based Browser Testing Instant access to all real mobile and desktop browsers. Say goodbye to your lab of devices and virtual machines.
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.
