jest-image-snapshot

v6.4.0(6 months ago)

This package is actively maintained.Types definitions are provided via a separate npm package: @types/jest-image-snapshotNumber of direct dependencies: 8Monthly npm downloads

jest-image-snapshot is a Jest plugin that enables snapshot testing for images in your JavaScript projects. It allows you to easily compare and validate visual changes in your application by capturing and comparing image snapshots. This is particularly useful for UI testing, ensuring that visual components render correctly and consistently.

Fight!

Functionality

Both Differencify and Jest Image Snapshot are npm packages used for visual regression testing. They allow you to compare screenshots of your application to detect any visual changes. However, Differencify provides more advanced features such as automatic baseline creation, pixel-level comparison, and support for multiple browsers. Jest Image Snapshot, on the other hand, is specifically designed for use with Jest testing framework and provides a simpler API for visual regression testing.

Integration

Differencify can be integrated with any testing framework, making it more flexible and suitable for different testing setups. Jest Image Snapshot, as the name suggests, is tightly integrated with Jest and provides seamless integration with Jest's snapshot testing functionality. If you are already using Jest for your testing, Jest Image Snapshot can be a convenient choice.

Developer Experience

Both packages have good documentation and active communities. Differencify has a more extensive documentation with detailed examples and guides. Jest Image Snapshot benefits from the popularity of Jest and has a large community, which means you can find more resources and support if needed.

Performance

In terms of performance, Differencify is known for its fast and efficient image comparison algorithm. It also supports parallel testing, which can significantly speed up the visual regression testing process. Jest Image Snapshot, being built on top of Jest, inherits Jest's performance characteristics. However, the performance may vary depending on the size and complexity of your test suite.

Popularity

Jest Image Snapshot benefits from the popularity of Jest, which is one of the most widely used testing frameworks in the JavaScript ecosystem. Differencify, although less popular, has gained a solid user base and is well-regarded among developers who require more advanced visual regression testing capabilities.
