Velocity test-package with html-reporter won't show anything

Question

My app is structured in packages, each with their corresponding test suites. I've added sanjo:jasmine as my testing engine and velocity:html-reporter, but when I run the following command I receive no output and the browser won't connect to the server in port 3000,

$ velocity test-package hogares --driver-package velocity:html-reporter@0.9.0

This is the test part of my package.js

Package.onTest(function(api) {
  api.use('ecmascript');
  api.use('sanjo:jasmine@0.20.2');
  api.use('hogares');
  api.addFiles('tests/server/hogares.specs.js', 'server');
  api.addFiles('tests/client/hogares.specs.js', 'client');
});

Any idea? Thanks!
