chore(deps): bump the jest group across 1 directory with 2 updates by dependabot[bot] · Pull Request #16360 · guardian/dotcom-rendering

dependabot · 2026-07-09T18:34:49Z

Bumps the jest group with 2 updates in the / directory: jest and jest-environment-jsdom.

Updates jest from 29.7.0 to 30.4.2

Release notes

v30.4.2

Fixes

[jest-runtime] Fix named imports from CJS modules whose module.exports is a function with own-property exports (#16150)

Full Changelog: jestjs/jest@v30.4.1...v30.4.2

v30.4.1

Features

[jest-config, jest-core, jest-runner, jest-schemas, jest-types] Allow custom runner configuration options via tuple format ['runner-path', {options}] (#16141)

Fixes

[jest-runtime] Align CJS-from-ESM default export with Node: module.exports is always the ESM default, __esModule unwrapping is no longer applied (#16143)

Full Changelog: jestjs/jest@v30.4.0...v30.4.1

v30.4.0

Big release! 😀

Main feature is a rewrite of our custom runtime in preparation for stabilisation of native support of ESM. As part of that work require(esm) module is now supported on Node 24.9+ (still requires --experimental-vm-modules like before).

In addition we now support fake timers for the recently released Temporal API in Node v26.

React 19 is also supported properly in pretty-format, meaning snapshots of React components now work like they should.

Due to all the changes, there might be regressions that snuck in. Please report them!

Full list of changes below

Features

[babel-jest] Support collecting coverage from .mts, .cts (and other) files (#15994)

[@jest/fake-timers] Accept Temporal.Instant and Temporal.ZonedDateTime in jest.setSystemTime() and useFakeTimers({now}) (#16128)

[jest-runtime] Use synchronous evaluate() for ES modules without top-level await on Node versions that support it (v24.9+), and prefer the synchronous transform path when a sync transformer is configured (#16062)

[jest-runtime] Validate TC39 import attributes (with { type: 'json' }) on ESM imports (#16127)
