> In stateAwareFilter description, it only allows one (1) application with a
> state that is not running in the list of candidates. The non-running state
> can be Starting or Accepted. However, in the following case, the last
> assertion cannot pass, because the result of candidate list is [appID0,
> appID1, appID2, appID3]. We should either update the description or fix the
> function.

> // stable sort is used so equal values stay where they were
> res := resources.NewResourceFromMap(map[string]resources.Quantity{

> // setup all apps with pending resources, all accepted state
> input := make(map[string]*Application, 4)
