Expect, a crucial component of the Jest testing framework, saw a minor version update from 27.2.2 to 27.2.3. While the description and core functionality remain consistent – providing the expect function for creating assertions in tests – a few dependency updates mark the key differences. Developers relying on specific versions of internal Jest packages should take note.
Specifically, @jest/types was updated from ^27.1.1 to ^27.2.3, jest-message-util from ^27.2.2 to ^27.2.3, jest-matcher-utils from ^27.2.2 to ^27.2.3, and @jest/test-utils from ^27.2.2 to ^27.2.3. These updates likely introduce bug fixes, performance improvements, or new features within the Expect's assertion messages or type definitions.
Developers using Expect directly outside of Jest might not experience significant changes unless they also explicitly depend on these updated internal packages. The ansi-styles, jest-get-type, jest-regex-util, chalk, immutable, and fast-check dependencies remain unchanged, indicating a focused update. The release date difference of a few days also signals that the update likely addresses minor problems or incorporates small improvements noticed after the 27.2.2 release. Users are advised to review the commit history or changelog for the affected Jest packages to understand the precise nature of the changes.
If you are using Jest and expect, it would be a good update!
