En mi caso, el nombre del archivo de configuración era diferente . Entonces, ejecutar el comando que especifica el archivo conf resolvió mi problema.
>> karma start unit-tests.conf.js
No captured browser, open http://localhost:9876/
...
Y para 'PhantomJS', al abrir el enlace especificado ( localhost: 9876 ) en el navegador se ejecutan los casos de prueba.
Espero eso ayude. :)
