This major upgrade from Jest 26 to 28 introduces significant breaking changes, including a new default test environment, removal of bundled packages, and API updates. Manual configuration and code changes are required.

Highlights:

• Test Environment: The default environment changed from jsdom to node. For browser-based tests, you must now explicitly install jest-environment-jsdom and set testEnvironment: 'jsdom' in your config.
• Configuration & API: The testURL option is removed; use testEnvironmentOptions instead. The expect package now uses a named export, so change import expect from 'expect' to import {expect} from 'expect'.

Source: Jest documentation
Recommendation: Carefully follow the official migration guides for v27 and v28, update your Jest configuration, and install jest-environment-jsdom before merging.
