1.js

var Scheduling = require("Scheduling");

describe("when running a schedule", function(){
  var schedule, mc;

  beforeEach(function(){
    schedule = new Scheduling.Schedule();
    schedule.build([]);
    spyOn(schedule, "on");

    mc = new MasterControl(schedule);
    mc.run();
  });

  it("should listen for ready jobs", function(){
    expect(schedule.on).toHaveBeenCalledWith("job.ready", jasmine.any(Function));
  });
});

2.js

var Scheduling = require("Scheduling");

3.js

var util = require("util");
var events = require("events");

function MockSchedule(){
  spyOn(this, "emit").andCallThrough();
  spyOn(this, "on").andCallThrough();

  this.processJobCompletion = jasmine.createSpy("processJobCompletion");
}

util.inherits(MockSchedule, events.EventEmitter);

module.exports = MockSchedule;

4.js

var MockSchedule = require("./helpers/MockSchedule");

describe("when running a schedule", function(){
  var schedule, mc;

  beforeEach(function(){
    schedule = new MockSchedule();
    schedule.build([]);

    mc = new MasterControl(schedule);
    mc.run();
  });

  it("should listen for ready jobs", function(){
    expect(schedule.on).toHaveBeenCalledWith("job.ready", jasmine.any(Function));
  });
});
