MockModuleOptions.defaultExport and MockModuleOptions.namedExports have been consolidated into a single option MockModuleOptions.exports to align with user expectations and other test runners.

A default property on MockModuleOptions.exports represents the default export, and own enumerable properties are treated as named exports.

An automated migration is available to update user code: https://github.com/nodejs/userland-migrations/tree/main/recipes/mock-module-exports
