Jenkins vs Jest: What are the differences?
What is Jenkins? An extendable open source continuous integration server. In a nutshell Jenkins CI is the leading open-source continuous integration server. Built with Java, it provides over 300 plugins to support building and testing virtually any project.
Some of the features offered by Jenkins are:
- Easy installation
- Easy configuration
- Change set support
On the other hand, Jest provides the following key features:
- 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
"Hosted internally" is the primary reason why developers consider Jenkins over the competitors, whereas "Open source" was stated as the key factor in picking Jest.
Jenkins and Jest are both open source tools. Jest with 26.1K GitHub stars and 3.53K forks on GitHub appears to be more popular than Jenkins with 13.2K GitHub stars and 5.43K GitHub forks.
Instacart, Lyft, and Twitch are some of the popular companies that use Jenkins, whereas Jest is used by Repro, Glympse, and Ubiqua. Jenkins has a broader approval, being mentioned in 1753 company stacks & 1479 developers stacks; compared to Jest, which is listed in 263 company stacks and 150 developer stacks.
