Jest Environment JSDOM version 27.0.3 is a minor update to the popular Jest testing environment that simulates a browser-like environment using JSDOM. Comparing it to the previous stable version, 27.0.2, the key changes lie primarily in dependency updates within the Jest ecosystem. Developers already familiar with version 27.0.2 will find this update a seamless transition.
Specifically, version 27.0.3 updates peer dependencies @jest/environment and @jest/fake-timers. This ensures compatibility and potentially incorporates bug fixes or performance improvements introduced in those individual packages. The jest-mock dependency is also bumped to version 27.0.3 from 27.0.2. These updates likely address internal refinements within the Jest framework to improve overall stability and reliability.
While the core functionality remains the same, this upgrade is beneficial for those staying current with the Jest ecosystem. Developers relying on the newest features or bug fixes within the dependent Jest packages will find version 27.0.3 essential. The development dependency @jest/test-utils and @types/jsdom remain the same. jsdom and @types/node also didn't receive updates. The releaseDate has also changed, with version 27.0.3 was released later. It is recommended to update to 27.0.3.
