How to turn off Velocity unit testing in Meteor?

I'm using the mike:mocha package and I'm trying to figure out how to disable testing.

I tried going to packages > test-proxy > package.js and changing debugOnly to false, but after reloading the page it automatically changes it back to true.

Package.describe({
    name: "velocity:test-proxy",
    summary: "Dynamically created package to expose test files to mirrors",
    version: "0.0.4",
    debugOnly: true
});

What are steps that needs to be taken, for Velocity, before putting an app out to production?
