Features

• [babel-jest] Support collecting coverage from .mts, .cts (and other) files (#​15994)
• [jest-circus, jest-cli, jest-config, jest-core, jest-jasmine2, jest-types] Add --collect-tests flag to discover and list tests without executing them (#​16006)

• [jest-mock] Add clearMocksOnScope(scope) on ModuleMocker for clearing every mock function exposed on a scope object (#​16088)
• [jest-resolve] Add canResolveSync() on Resolver so callers can detect when a user-configured resolver only exports an async hook (#​16064)
• [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)

• [jest-config] Allow collectCoverage and coverageProvider in project config without a validation warning (#​16132)
• [jest-config] Project config validator now emits "is not supported in an individual project configuration" instead of "probably a typing mistake" for known global-only options (#​16132)
• [jest-environment-node] Fix --localstorage-file warning on Node 25+ (#​16086)
• [jest-reporters] Apply global coverage threshold to unmatched pattern files in addition to glob/path thresholds (#​16137)
• [jest-reporters, jest-runner, jest-runtime, jest-transform] Fix coverage report not showing correct code coverage when using projects config option (#​16140)
• [jest-runtime] Resolve expect and @jest/expect from the internal module registry so test-file imports share the same JestAssertionError as the global expect (#​16130)
• [jest-runtime] Improve CJS-from-ESM interop: __esModule/Babel default unwrap, broader named-export coverage, and shared CJS singleton across importers (#​16050)
• [jest-runtime] Load .js files with ESM syntax but no "type":"module" marker as native ESM (#​16050)
• [jest-runtime] Extend the .js-with-ESM-syntax fallback to require() on Node v24.9+ - falls back to require(esm) when the CJS parser rejects ESM syntax (#​16078)
