chore: migrate Jest from v27 to v28

[cryptodev-2s]

Explanation

Update Jest and related testing packages across the monorepo:

• jest: ^27.5.1 → ^28.1.3
• @types/jest: ^27.4.1 → ^28.1.8
• ts-jest: ^27.1.4 → ^28.0.8
• jest-environment-jsdom: ^27.5.1 → ^28.1.3

The changelogs for the two breaking changes of ts-jest are here:

• 28: https://github.com/kulshekhar/ts-jest/blob/main/CHANGELOG.md#2800-2022-05-02
• 29: https://github.com/kulshekhar/ts-jest/blob/main/CHANGELOG.md#2900-2022-09-08

None of the breaking changes seem to impact us.

Note

Medium Risk
Broad test-infrastructure upgrade across many packages may surface subtle Jest/ts-jest and environment behavior changes (timers, module resolution, custom environments), potentially causing flaky or failing tests.

Overview
Migrates the monorepo test stack from Jest v27 to v28. This bumps jest, @types/jest, and ts-jest across packages, and adds jest-environment-jsdom/jest-environment-node where needed.

Updates Jest configuration and environment wiring: moduleNameMapper now forces CommonJS resolutions for uuid (and yaml in package tests) to avoid ESM/bundler issues, and custom environments switch to importing { TestEnvironment } from the Jest environment packages.

Adjusts a handful of tests/helpers for v28 behavior, including replacing jest.useFakeTimers('modern') usage and updating a timeout-recorder helper to flush microtasks via Promise.resolve() instead of jest.runOnlyPendingTimers(). Also updates .depcheckrc.yml ignores for the new Jest environment packages.

Warning

MetaMask internal reviewing guidelines:

• Do not ignore-all
• Each alert has instructions on how to review if you don't know what it means. If lost, ask your Security Liaison or the supply-chain group
• Copy-paste ignore lines for specific packages or a group of one kind with a note on what research you did to deem it safe.

Action	Severity	Alert  (click "▶" to expand/collapse)
Warn		Potential code anomaly (AI signal): npm http-proxy-agent is 100.0% likely to have a medium risk anomaly Notes: The code fragment is a conventional HTTP proxy agent component handling optional proxy authentication and dynamic header adjustments. There is no evidence of malicious activity, data exfiltration, or supply-chain abuse within this fragment. The main concerns relate to reliance on internal Node.js fields (version fragility) and potential in-memory exposure of credentials, but these are standard operational caveats for proxy clients and do not indicate malice. Confidence: 1.00 Severity: 0.60 From: ? → npm/jest-environment-jsdom@28.1.3 → npm/http-proxy-agent@5.0.0 ℹ Read more on: This package | This alert | What is an AI-detected potential code anomaly? Next steps: Take a moment to review the security alert above. Review the linked package source code to understand the potential risk. Ensure the package is not malicious before proceeding. If you're unsure how to proceed, reach out to your security team or ask the Socket team for help at support@socket.dev. Suggestion: An AI system found a low-risk anomaly in this package. It may still be fine to use, but you should check that it is safe before proceeding. Mark the package as acceptable risk. To ignore this alert only in this pull request, reply with the comment @SocketSecurity ignore npm/http-proxy-agent@5.0.0. You can also ignore all packages with @SocketSecurity ignore-all. To ignore an alert for all future pull requests, use Socket's Dashboard to change the triage state of this alert.
