Expect, a core component of the Jest testing framework, saw a version update from 26.4.2 to 26.5.0, bringing several notable changes that developers should be aware of. Both versions serve the same fundamental purpose: providing the expect function for writing expressive and reliable tests as documented on Jest's website. The key differences lie in dependency updates.
Version 26.5.0 upgraded its dependencies on @jest/types, jest-message-util, and jest-matcher-utils bringing it to 26.5.0. In contrast, version 26.4.2 relied on older versions (26.3.0, 26.3.0, and 26.4.2, respectively) of the same packages. Similarly, the @jest/test-utils dependency was bumped to 26.5.0 from 26.3.0. These dependency updates likely include bug fixes, performance improvements, and potentially new features within those specific Jest utilities. Developers should check the changelogs for those individual packages to understand the precise nature of the changes.
Furthermore, the internal unpackedSize indicates a minimal change in the size of the package (164577 vs 164356), suggesting only small adjustments within. The release date also highlights the recency of the update, with version 26.5.0 released later. In summary, the update of the expect library from version 26.4.2 to 26.5.0 is characterized by updated dependencies, likely resulting in improved stability and potentially new features inherited from those dependencies. Users are advised to update, while referencing the respective changelogs.
