Gulpfile and tests

What is the relation between ionic-cli and the generated initial gulpfile.js:

  • where/how is the gulpfile.js generated by ionic start myapp <template>
  • is the ionic.project documented somewhere: in particular the relation between gulpStartupTasks and watchPatterns
  • Any chance we could contribute something akin to ionic setup sass for setting up unit/e2e tests

I would like to add tests in the most ionic-y way possible,
Thanks
