Jest version 28.1.2 represents a minor update to the popular JavaScript testing framework, building upon the foundation laid by version 28.1.1. Both versions share the core philosophy of providing a delightful testing experience, boasting identical descriptions. The dependency structures are largely consistent, with jest-cli, @jest/core, @jest/types, and import-local remaining fundamental components. Development dependencies for type definitions and related tooling (tsd-lite and @tsd/typescript) are also unchanged. The peer dependency on node-notifier for cross-platform notifications is maintained, ensuring compatibility with relevant notifier versions. Licensing under the MIT license and repository details also remain consistent.
The key differences reside in the release timing and the specific patch versions of dependent packages. Version 28.1.2 appeared on June 29, 2022, a little over three weeks after 28.1.1's release on June 7, 2022. Developers should note the subtle updates to internal dependencies like jest-cli and @jest/core whichincremented from 28.1.1 to 28.1.2 along with the main package. This suggests bug fixes, performance improvements, or minor feature enhancements within those modules. The @jest/types dependency however remained unchanged. Given the minor version bump, upgrading from 28.1.1 to 28.1.2 is generally recommended for a more stable and refined testing environment, incorporating any fixes or optimizations implemented in the intervening period. Developers should review the changelog for detailed specifics of changes included.
