Corredor de prueba de karma – no logra capturar chrome

Estoy usando Yeoman para generar una aplicación AngularJS. Ejecutar el grunt serve para pre-visualizar mi aplicación funciona bien, pero cuando bash ejecutar las pruebas usando la grunt test , obtengo el siguiente error en mi consola:

  • nodo v0.10.23
  • Versión Karma: 0.10.8

¿Qué me estoy perdiendo?

Cambiar el puerto predeterminado (8080) a 9876 en el archivo karma.conf.js solucionó el problema para mí
