Angular-cli: de las opciones de prueba no registradas

Estoy usando Mac OS X El Capitan con:

• angular-cli: 1.0.0-beta.5
• nodo: 6.2.0
• sistema operativo: darwin x64

Algunas opciones de ng test parecen no funcionar, por ejemplo, ng test --filter x impresiones:

The option '--filter' is not registered with the test command. Run `ng test --help` for a list of supported options.

Aunque se imprime cuando se ejecuta ng test --help :

(node:2838) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.
Could not start watchman; falling back to NodeWatcher for file system events.
