[dependabot]

Bumps babel-jest from 30.4.1 to 30.5.2.

Release notes

Sourced from babel-jest's releases.

v30.5.2

Features

• [@jest/transform] Strip TypeScript types with Node when no transformer claims a .ts, .mts or .cts file (#16421)

Fixes

• [jest-core, jest-haste-map, jest-transform] Keep require('../package.json') external when bundling, so jest --version and the transform and haste-map cache keys report the released version instead of the previous one (#16422)
• [jest-each] Escape a table row's keys before building the $variable interpolation RegExp, so a column name such as count(*) no longer fails the whole table with Invalid regular expression, and a . or | in a column name is matched literally (#16345)
• [@jest/source-map] Resolve absolute Windows paths in a source map's sources and sourceRoot again, instead of appending them to the transformed file's directory (#16439)

New Contributors

• @​winklemad made their first contribution in jestjs/jest#16345

Full Changelog: jestjs/jest@v30.5.1...v30.5.2

v30.5.1

Fixes

• [jest-config] Don't warn about global-only options in the config that supplies the global config - the root config a project resolves to, or the first entry of --projects when no root config is passed (#16411)
• [jest-config, jest-types] Stop accepting reporters, coverageReporters, workerIdleMemoryLimit, cwd and runnerOptions in a project config - they were silently ignored, and now warn like the other global-only options (#16411)
• [jest-config, jest-validate] Warn about maxWorkers and coverageThreshold in a project config instead of dropping them without a word (#16411)
• [jest-resolve] Match moduleNameMapper patterns against the specifier as written again (reverting #16390) (#16417)
• [jest-runtime] Resolve package imports specifiers like #dep under ESM again (#16413)

Chore & Maintenance

• [jest-util] Name the testEnvironmentOptions.globalsCleanup option and link the docs from the JEST-01 deprecation warning, and document the option's modes (#16404)

v30.5.0

On a personal note: King Harald V of Norway passed away this morning. He ascended the throne 35 years ago, two months before I was born. This release is dedicated to his memory. Hvil i fred 🇳🇴

---

This is a big release. It touches jest-runtime, jest-resolve and jest-haste-map in many places, and with this many changes there might be regressions 😬. If your suite behaves differently after upgrading, please open an issue.

Highlights

whenCalledWith

Mock functions can now configure return values per argument list, contributed by @​timkindberg (#16053):

const fn = jest.fn();
fn.whenCalledWith('apple').mockReturnValue('red');

30.5.0

Features

• [@jest/expect-utils, jest-mock] Add mockFn.whenCalledWith(...args) for configuring return values per argument list, with first-class asymmetric-matcher support (#16053)
• [@jest/expect-utils] Export AsymmetricMatcher and FunctionParameters types (previously private to expect) (#16053)
• [jest-circus, jest-core, jest-jasmine2, jest-test-result, jest-types] --collectTests now expands test.each/describe.each cases and reports per-status counts (skipped/todo via the new wouldRun flag for selected tests) plus a summary line that match a real run, including under --testNamePattern and .only/fdescribe focus on both the circus and jasmine2 runners (#16259)
• [jest-circus, jest-environment, jest-runtime, jest-types] Add describe-level retries via jest.retryTimes(..., {entireDescribe: true}) (#16322)
• [jest-circus, jest-message-util, jest-reporters, jest-types] Add retryMessages to AssertionResult and export formatErrorStack, so the retry log renders nested cause and AggregateError sections with code frames instead of serialized [cause]:/[errors]: markers (#16316)
• [jest-circus, jest-types] Add unhandledErrorsDetailed to Circus.RunResult, so an unhandled rejection reports its cause chain and AggregateError entries with code frames instead of a pre-serialized stack (#16316)
• [jest-haste-map] Replace NodeWatcher and FSEventsWatcher with @parcel/watcher for the non-watchman watch path (#16188)
• [jest-resolve] Bump unrs-resolver to 1.12.1, remove jest-pnp-resolver and unnecessary checks (#15721)
• [jest-resolve] Honor Node's --preserve-symlinks / NODE_PRESERVE_SYMLINKS in the default resolver by passing symlinks: false to unrs-resolver (#16260)
• [jest-runtime] Apply automocking and manual __mocks__ files to synchronously evaluable ESM graphs on Node 24.9+ - static imports, dynamic import() and require() of an ESM file now generate an automock from the real module's namespace instead of failing with "Attempting to import a mock without a factory". Graphs that need async evaluation (top-level await) or an async-only resolver or transformer still throw (#16391)
• [jest-runtime] Route process.getBuiltinModule through the sandbox, so it returns the sandbox process and the hooked node:module instead of the host's (#16391)
• [jest-runtime] Throw an actionable error from module.register() and module.registerHooks() inside a test - the hooks attached to the loader running Jest itself, never saw the sandboxed requires they were meant for, and stayed registered for every later test file in the worker (#16391)
• [jest-runtime] Surface resolution and import-attribute errors in an ESM graph before executing any of its CJS dependencies on Node 24.9+, matching Node's run-nothing-on-a-broken-graph behavior; the legacy loader on older versions keeps its linking-time execution order (#16391)
• [jest-runtime] Throw ERR_SOURCE_PHASE_NOT_DEFINED with an actionable message for import source and import.source(), instead of failing at instantiation with V8's bare "Source phase import object is not defined" (#16391)
• [jest-runtime] Emit the JSON-without-import-attribute deprecation warning once per test file instead of once per worker, so it is no longer silently swallowed for every file after the first (#16391)
• [jest-runtime] Set import.meta.main to true in the test file and false in every module it loads, matching Node 24+ (#16367)
• [jest-runtime] Resolve the module-sync export condition, so a package that exposes its ESM entry point for require() loads the same file Node would (#16336)
• [jest-snapshot] Add external snapshot paths to custom reporter failure details (#16374)
