回答1:

You need a ui-view directive in the template of the parent state (the test state):

  template:'<div ui-view/> <a ui-sref="test">Parent</a>  <a ui-sref=".child1">child1</a></div>',

Basically whenever you have a state in ui-router which will have child states, the immediate parent pf that child state must also have a ui-view directive in its template.

Posting this as answer as I do not have enough reps to comment. As mentioned by Mohammad, you need a ui-view inside the template of the parent state. The ui-view in your Index html only allows you to render the parent state(test state), but in order for .child1 state to be rendered, it needs another ui-view inside its parent state, which in this case is the test state.

Thus, configure your test state's template to contain a ui-view:

angular.module('uiRouterSample.contacts', ['ui.router'])
.config(['$stateProvider', '$urlRouterProvider',
   function ($stateProvider,   $urlRouterProvider) {
     $stateProvider
       .state('test',{
         url:'/test',            
         template:'<div ui-view/> <a ui-sref="test">Parent</a> -> <a ui-sref=".child1">child1</a></div>',
         controller: ['$scope', '$state', 'contacts', 'utils',
           function (  $scope,   $state,   contacts,   utils) {
           }]})
    .state('test.child1',{
        url:'/child1',            
        template:'Child template working fine'
    })
   }]
