Jest Environment JSDOM version 26.2.0 introduces several updates compared to its predecessor, version 26.1.0. Primarily, the core Jest dependencies have been bumped to their 26.2.0 counterparts. This includes jest-mock, jest-util, @jest/types, @jest/environment, and @jest/fake-timers. This synchronization across the Jest ecosystem ensures better compatibility and access to the latest features and bug fixes within those individual packages. For developers, this means potentially benefiting from performance improvements, enhanced mocking capabilities in jest-mock, and more robust type definitions brought by @jest/types.
A notable addition in 26.2.0 is the explicit declaration of @types/node as a dependency. Although specified with "*", It's a change. While @types/node may have been an implicit dependency previously, explicitly stating it can help prevent resolution issues or unexpected behaviors in environments where Node.js types are not automatically included.
The updated version also incorporates minor changes to the package's metadata, reflected in the increased unpackedSize (7551 bytes vs 7527 bytes) and the updated releaseDate. From a developer's perspective, upgrading to 26.2.0 provides a more consistent and up-to-date testing environment, leveraging the latest advancements within the Jest framework. While the core functionality might remain similar, these dependency updates contribute to a more stable and feature-rich experience for writing and running JavaScript tests in a JSDOM environment.
