add status to suites

[fcarstens]

This PR fixes #19. The suite status is available at globalSuite.getTotal().status. test.errors should already be there?

I'm still not happy with the getTotal() method. Can we just run this inside the constructor and add the properties to the instance? Though according to our current draft, there should be runtime, suites, tests and status.

This is problematic if we want to pass Test and Suite objects on the start events as well. We would then need to recalculate them somehow later on... Alternatively, we could use es5 getters:

class Suite {
  constructor(){
    this.tests = [1,2,3]; // Simple Demo
  }
  getAllTests(){
    return this.tests;
  }
  get total(){
    return this.getAllTests().length;
  }
}
Object.defineProperties(Suite.prototype, {
  toJSON: {
    value: function(){
      let ret = {};
      for(let x in this){
        ret[x] = this[x];
      }
      return ret;
    }
  },
  total: {
    enumerable: true
  }
})

var s = new Suite();
console.log(s.total, JSON.stringify(s));
// 3 {"tests":[1,2,3],"total":3}

What do you think?

Okay, let's give that a try.

I implemented this on top of the test stuff: https://github.com/fcarstens/js-reporters/tree/suite_summary Shall I open a new PR?

[jzaefferer]

Maybe rebase #23 into a set of reasonably atomic commits, than add this on top?

[fcarstens]

Included in #23.
