Question

我正在为我的角度控制器编写单元测试;从服务接收$ resource对象。

然而单元测试失败说“Action.query（success）'不是函数。

期待您的意见。

$inject数组中值的排序必须与ActionController中参数的排序相匹配。

ActionController.$inject = ['$sce', 'ActionService'];

/* @ngInject */
// 'actionService' must be the second parameter in the 'ActionController' function.
function ActionController($sce, actionService, $state, $stateParams, logger, exception,
                       moduleHelper, httpHelper) {
    var vm = this;       
    var Action = null;

    // the rest of the code.
