Jest vs CodeceptJS: What are the differences?
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.
