Angular Unit Test - 点击指令不触发

Question

问题

我正在尝试从指令模板中单击带有value="agency" 的radio 输入，最终目标是更改范围变量newDatasourceType。

指令模板

  <div ng-if="!datasources" class="new-datasource">
        <input name="agencyOrWidget" type="radio" ng-model="newDatasourceType" value="agency" />
        <label>Agency</label>
        <input name="agencyOrWidget" type="radio" ng-model="newDatasourceType" value="widget" />
        <label>Widget</label>
        <select ng-if="newDatasourceType=='widget'" name="{{inputPrefix}}[0][widget_id]">
              <option>Choose a widget...</option>
              <option ng-repeat="(id, options) in widgetList" value="{{id}}">{{id}}</option>
        </select>
        <select ng-if="newDatasourceType=='agency'" name="{{inputPrefix}}[0][agency_id]">
              <option>Choose an agency...</option>            
              <option ng-repeat="(id, name) in agenciesList" value="{{id}}">{{name}}</option>
        </select>
  </div>

尝试的部分和注释在 cmets 中。

it('Select Agencies', function() {
    // Running this to see if it does anything
    scope.newDatasourceType = 'agency';

    //create the element with the directive template
    elem = $compile(directive)(scope);
    scope.$digest();

    // Returns `1`
    console.log(elem.find('input[value="agency"]').length);

    // elem.find('input[value="agency"]').triggerHandler('click');
    elem.find('input[value="agency"]').click(function() {
        // Doesn't get triggered
        console.log('click');
    });

    // Didn't do anything...
    // scope.$digest();
    // scope.$apply();


    // console.log(elem.html());

    // Test items
    expect(elem.find('select option:nth-child(2)').val()).toBe(Object.keys(scope.agenciesJson)[0]);
});

我所看到的

无论我手动设置newDatasourceType 还是尝试点击它，只有Choose a widget... 的选择块可见。

除了触发click 事件之外，您还必须更改单选按钮上的checked 属性。这是一个例子http://jsfiddle.net/k1axxs21/1/
