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)

Fixes

• [jest-console, jest-reporters] CustomConsole now buffers console output so TestResult.console is populated for reporters when verbose is enabled, while GitHubActionsReporter avoids replaying buffered output in verbose mode (#​16155)
• [expect, jest-message-util, jest-pattern, jest-regex-util, jest-util] Revert node: protocol imports to restore webpack/browser-bundle compatibility (#​16167)
• [expect] Widen toMatchObject and objectContaining parameter type from Record<string, unknown> to object so class instances are accepted (#​16196)
• [jest-circus] Call a generator test body with the shared test context, so this matches what a regular test function receives (#​16347)
• [jest-circus] Capture the error listeners of the parent process instead of the in-sandbox process, so listeners registered before the test file survive teardown and sandbox listeners no longer leak onto the parent (#​16347)
• [jest-circus] Clear currentlyRunningTest after skipped and todo tests (#​16342)
• [jest-circus] Prevent late done() callbacks from affecting later test or hook invocations (#​16343)
• [jest-circus, jest-jasmine2] Honor --expand when formatting node:assert failures, instead of always collapsing the diff (#​16347)
• [jest-circus, jest-jasmine2, jest-message-util] Serialize the inner errors of an AggregateError into failureMessages, retryReasons and unhandledErrors, so --json output and reporter annotations include them (#​16316)
• [jest-circus, jest-snapshot] Keep snapshot state and counts correct when a test retries (#​16344)
• [@jest/create-cache-key-function] Include the caller support flags in the generated key, so a transformer that emits ESM or CJS based on them no longer shares one cache entry between the two (#​16331)
• [@jest/create-cache-key-function] Include the stringified project config in the generated key, so editing a transformer's own settings invalidates what it cached (#​16331)
• [@jest/transform] Include the caller support flags in a transform's cache key, so a file transformed both as ESM and as CJS no longer serves one shape's output for the other (#​16331)
• [jest-config] Add missing findRelatedTests, outputFile, and replname entries to ValidConfig so they no longer trigger spurious "Unknown option" warnings (#​16224)
• [jest-config] Use --config for the global config when multiple --projects are specified (#​16273)
• [jest-core] Serialize bigint values in --json and --outputFile output as their literal form (4n), instead of failing the run with TypeError: Do not know how to serialize a BigInt (#​16338)
• [jest-core] Do not report a CustomGC async resource (used by N-API addons such as napi-rs for per-isolate GC bookkeeping) as an open handle, since it is napi_unref'd by the addon and can never keep the event loop alive (#​16379)
• [jest-each] Keep a $&, $`, $' or $$ inside a %p param value out of the replacement, so the title shows the value instead of the text around it (#​16338)
• [jest-each] Interpolate a bigint into a %j title as its literal form ("4n") at any depth, instead of throwing TypeError: Do not know how to serialize a BigInt while collecting the tests (#​16338)
• [jest-environment, jest-runtime] Bind sandboxInjectedGlobals to the right values when injectGlobals is false, instead of shifting every one of them by a position (#​16377)
• [jest-environment-node, jest-util] Only warn about a conflicting globalsCleanup mode when one was explicitly configured, and follow the mode that is actually in effect (#​16323)
• [jest-environment-node, jest-util] Stop resolving lazy globals when setting up an environment, so Node 26's builtin module globals are no longer loaded (and no longer emit their deprecation warnings) for every test file (#​16324)
• [jest-haste-map] Keep watch mode alive when an outside process briefly makes a file unreadable on Windows, instead of tearing the watcher down on EPERM (#​16295)
• [jest-haste-map] Keep indexing when an outside process holds a file open on Windows, instead of failing the whole crawl on EPERM (#​16358)
• [jest-haste-map] Keep a duplicated manual mock resolving when the file it pointed at is deleted in watch mode (#​16360)
• [jest-haste-map] Shut the worker farm down when a duplicate manual mock aborts the build under throwOnModuleCollision (#​16354)
• [jest-haste-map] Attach the watchman client's error listener before the first command, so a watchman failure falls back to the node crawler instead of crashing on an unhandled error event, and always end the client (#​16355)
• [jest-haste-map] Stop delivering watch events after WatchmanWatcher is closed, and route its warnings through the configured console (#​16355)
• [jest-haste-map] Restore the nested duplicates index correctly in ModuleMap.fromJSON, so a haste collision reported inside a test worker raises DuplicateHasteCandidatesError instead of a TypeError (#​16353)
• [jest-haste-map] Match watched files on a full extension, so moduleFileExtensions: ['js'] no longer accepts foo.mjs (#​16352)
• [jest-haste-map] Delimit the fields that make up the haste map cache key, so two different option sets cannot hash to the same cache file (#​16352)
• [jest-message-util] Print the inner errors of an AggregateError thrown inside a test (#​16316)
• [jest-message-util] Indent nested cause and AggregateError sections of a test failure by one level per depth, so the nesting is legible instead of rendering flat (#​16316)
• [jest-message-util] Color stack traces line by line so blank lines stay blank (#​16316)
• [jest-message-util] Detect Jest's own frames without assuming the checkout directory's name, and cover @jest/* packages, so stack traces and code frames point at user code (#​16326)
• [jest-mock] mockResolvedValue / mockRejectedValue now see all overload return types, so a Promise-returning overload survives even when a later overload returns a non-Promise (e.g. pg.Client['end']) (#​16237)
• [@jest-environment/jsdom-abstract] Make @types/jsdom a peer dependency (#​16166)
• [jest-mock] Remove the leftover own accessor descriptor when restoring a spyOn of an inherited getter or setter, so the instance keeps reflecting the prototype (#​16226)
• [jest-resolve] Include extensionsToTreatAsEsm in the shouldLoadAsEsm cache key, so projects with different extension lists don't read each other's answers (#​16369)
• [jest-resolve] Make getModuleIDAsync build and cache data: URI module IDs the same way as getModuleID (#​16370)
• [jest-resolve] Keep the node: prefix when resolving a core module asynchronously, so a builtin that only exists prefixed (node:sea, node:sqlite, node:test, node:test/reporters) resolves instead of failing as a missing bare package (#​16388)
• [jest-resolve] Look up manual mocks for node: protocol specifiers under the unprefixed name they are stored as (#​16388)
• [jest-resolve] Apply moduleNameMapper consistently to both spellings of core module specifiers (fs vs node:fs) (#​16390)
• [jest-resolve] Keep virtual and ordinary mock module IDs isolated across test files (#​16296)
• [jest-resolve] Guard missing require.resolve.paths (#​16052)
• [jest-resolve, jest-config, jest-runner] Support a user resolver written as an ES module (#​16332)
• [jest-resolve, jest-runtime] Throw the CJS parse error for ESM syntax in a "type": "commonjs" package or a .cjs file instead of loading it as ESM, matching Node (#​16368)
• [@jest/source-map] Keep source map sources that name a scheme, such as webpack:///, instead of resolving them into a path that does not exist (#​16327)
• [@jest/source-map] Look up --testLocationInResults positions at the right column, and keep a mapping to the first column instead of discarding it (#​16327)
• [@jest/source-map] Warn when a source map cannot be parsed, instead of silently leaving its frames untranslated (#​16327)
• [jest-runner, @jest/source-map] Keep a source-mapped stack for an error thrown after the test environment was torn down (#​16327)
• [jest-runtime, @jest/source-map] Keep source maps past teardown and past the next test file's install, so a stack from a file no earlier stack mentioned still points at the original source (#​16330)
• [jest-runtime] Report that no coverage was collected when getAllV8CoverageInfoCopy is called after teardown, instead of returning an empty result (#​16385)
• [jest-runtime] Cache a CJS module's parsed exports before walking its re-exports, so two modules that re-export each other no longer overflow the stack when imported from ESM (#​16363)
• [jest-runtime] Keep a re-exported ES module's parse failure from marking the re-exporting CommonJS file as ESM, so module.exports = require('./dep.mjs') loads instead of failing with module is not defined (#​16363)
• [jest-runtime] Scope module mocks instantiated inside jest.isolateModules/isolateModulesAsync to that block, so a mock first imported there no longer outlives it - matching how CommonJS mocks already behave (#​16365)
• [jest-runtime] Suspend module isolation while generating an automock, so loading the real module to read its shape no longer populates the isolated registry (#​16365)
• [jest-runtime] Check a cached ES module's status before require() returns it, so a module whose evaluation threw rethrows that error and one left linked by a failed sibling is evaluated instead of returning uninitialized bindings (#​16364)
• [jest-runtime] Report the original ERR_REQUIRE_ASYNC_MODULE when a require() of a top-level-await graph is retried, instead of a spurious "concurrent import()" error (#​16364)
• [jest-runtime] Throw the evaluation error when another caller's import() of the same module failed while we awaited it, instead of resolving with the errored module (#​16364)
• [jest-runtime] Mark the result of require()ing an ES module that has a default export with __esModule: true through a live-binding facade, and serve the same object from require.cache, matching Node (#​16367)
• [jest-runtime] Provide a CommonJS module's exports under the 'module.exports' named export when imported from ESM, matching Node 23+ (#​16367)
• [jest-runtime] Give the test file itself a non-null require.main (#​16367)
• [jest-runtime] Populate module.children with the modules a file loads, matching Node (#​16368)
• [jest-runtime] Provide import.meta.resolve and import.meta.jest in data: URI modules, accept any-case mediatype parameters, and use Node's error codes for invalid data: URIs (#​16368)
• [jest-runtime] Key ES modules by full URL, so query and fragment suffixes create the same module instances as Node and show up in import.meta.url (#​16375)
• [jest-runtime] Share modules between overlapping graphs when a CommonJS module require()s an ES module mid-load, instead of evaluating shared dependencies twice (#​16375)
• [jest-runtime] Throw ERR_REQUIRE_CYCLE_MODULE like Node when a CommonJS module require()s an ES module that is still being loaded, instead of evaluating the module a second time (#​16366)
• [jest-runtime] Key builtin modules in the ESM registry by one canonical specifier (#​16341)
• [jest-runtime] import.meta.resolve() for a builtin uses its node: specifier (#​16341)
• [jest-runtime] Fall back to native ESM when a .js file contains ESM syntax but has no "type":"module" marker (#​16152)
• [jest-runtime] Allow require() of ESM-marked files on Node < 24.9 via transform fallback (#​16244)
• [jest-runtime, @jest/transform] Surface actionable ERR_REQUIRE_ESM error for files with untransformed ESM syntax instead of the generic "unexpected token" message (#​16244)
• [jest-runtime] Support older test environments whose moduleMocker does not implement clearMocksOnScope (#​16169)
• [jest-runtime] Apply jest.unstable_mockModule when the mocked file itself is require()d, not only when it is imported as a dependency (#​16389)
• [jest-runtime] Apply jest.unstable_mockModule to statically imported data: URIs on Node 24.9+, matching dynamic import() (#​16389)
• [jest-runtime] Run an async jest.unstable_mockModule factory once per module instead of twice, and fail the import instead of crashing the worker when the factory rejects (#​16389)
• [jest-runtime] Hide a require(esm) module that failed to evaluate from require.cache, as Node does, instead of exposing a namespace with uninitialized bindings (#​16389)
• [jest-runtime] Strip the byte-order mark when importing a JSON module, matching require() and Node (#​16389)
• [jest-runtime] Throw ERR_REQUIRE_ASYNC_MODULE when require(esm) runs under an async-only custom resolver, instead of silently resolving with the default resolver (#​16389)
• [jest-runtime] Parse imported JSON modules with the test realm's JSON, so their objects pass instanceof Object inside the test like require()d JSON does (#​16389)
• [jest-runtime] Accept every file: URL string in the sandboxed module.createRequire, including one with a localhost authority, as Node does (#​16389)
• [jest-runtime] Point at {virtual: true} when jest.mock or jest.unstable_mockModule is given a module that cannot be resolved (#​16389)
• [jest-reporters] Fix coverage report table formatting in CI/GitHub Actions environments where process.stdout.columns is undefined by falling back to the COLUMNS env var or 80 columns in CI, preserving existing behaviour in other non-TTY environments (#​16227)
• [jest-runtime] Support CJS-in-ESM exports via "module.exports" named exports (#​16277)
• [jest-snapshot] Keep a skipped or failed test's hinted snapshots, instead of reporting them obsolete (#​16348)
• [jest-util] Stop globsToMatcher reusing a cached matcher compiled with different picomatch options, and keep its dot: true default when dot is passed as undefined (#​16381)
• [pretty-format] Move the react-is aliases into the @jest scope, so they cannot be shadowed by unrelated packages published under the alias names (#​16333)

Chore & Maintenance

• [jest-haste-map] Drop walker dependency; replace hand-rolled directory recursion in the JS crawler and watcher startup with fdir (#​16187)
• [jest-haste-map] Reuse cached metadata for files whose haste name is a known duplicate, instead of re-reading and re-parsing them on every startup (#​16351)
• [jest-haste-map] Cache the watchman socket path and replace the watchman --version probe with get-sockname, so warm runs spawn no watchman processes (#​16386)
• [jest-resolve] Store the per-directory package-type lookup in the cache it reads, so it actually memoizes (#​16369)
• [jest-resolve, jest-runtime] Cut repeated work on the resolution hot path: hoist the platform-extension list to construction, memoize isCoreModule and the options cache-key serialization, skip mapper preparation when no moduleNameMapper is configured, run each mapper regex once, and stop re-parsing NODE_OPTIONS on every default-resolver call (#​16371)
• [jest-resolve] Cut warm resolution cost to about a third: reuse one unrs-resolver factory per options shape instead of cloning per resolution, compose the factory cache key from per-array cached strings instead of serializing options, and stop constructing an Error for misses that findNodeModule swallows; add a __benchmarks__ suite for the default resolver (#​16373)
• [jest-runner, @jest/source-map] Replace source-map-support with an implementation in @jest/source-map (#​16327)
• [jest-snapshot] Load babel, semver and synckit lazily, so requiring the package (which every test process does through @jest/expect) no longer loads ~200 modules that only writing inline snapshots needs (#​16387)
• [jest-runtime] Reduce per-require overhead: skip module ID resolution when no mock can apply, answer core modules before probing for a manual mock, share one require.cache proxy across modules, and cache empty files (#​16376)
• [@jest/source-map] Deprecate getCallsite in favour of SourceMapSupport#getCallsite (#​16327)
• [jest-runtime] Avoid magical null value in ESM loader (#​16160)
