jasmine - 预期未定义要定义我该如何解决

Question

我正在尝试使用 Jasmine 测试我的 Angular，但不知何故，我一直收到此错误 Expected undefined to be defined 并且我遵循了我在平均堆栈上的 Angular 文档示例

测试.js

describe('测试 Ecdreport Controller ', function(){
var $范围， Controller ；

var app = angular.module('mean.ecdreport',[])
.controller('EcdreportController', ['$scope', '$http', 'Global', 'Ecdreport', function($scope, $http, Global, Ecdreport) {
    $scope.global = Global;
    $scope.query = "";
    $scope.package = {

    };
    

            $scope.startDate = null;
            $scope.endDate = null;

it('Testing Scope', function(){

    expect($scope.getDataModel).toBeDefined();

您会收到该错误，因为您的测试 Controller 从未被定义。您需要使用 var controller = ...
您应该像这样使用 Controller 注入(inject):

beforeEach(inject(function(_$rootScope_,_$controller_){
    $scope = _$rootScope_.$new();
    createController = function() {
        return _$controller_('EcdreportController', {
           $scope : $scope
        });
    };
}));

并像这样在每个测试中初始化 Controller :

it('Should be registered', function(){
    var controller = new createController();
    expect(controller).toBeDefined();
})

这样，如果您的 Controller 需要传递任何数据，您还可以在每个测试中传递不同的参数。
