Codecov vs Jest: What are the differences?
What is Codecov? Hosted coverage reports with awesome features to enhance your CI workflow. Our patrons rave about our elegant coverage reports, integrated pull request comments, interactive commit graphs, our Chrome plugin and security.
What is Jest? Painless JavaScript Unit Testing. Jest provides you with multiple layers on top of Jasmine.
Codecov can be classified as a tool in the "Code Coverage" category, while Jest is grouped under "Javascript Testing Framework".
Some of the features offered by Codecov are:
- Beautiful Reports
- Pull Request Comments
- Interactive Commit Graphs
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
"More stable than coveralls" is the top reason why over 14 developers like Codecov, while over 24 developers mention "Open source" as the leading cause for choosing Jest.
