使用jasmine进行测试时，未定义注入的服务

Question

出于某种原因，当我运行测试时，Jasmine告诉我“DataFactory”未定义。有什么想法吗？

angular.module('MyApp')
.factory('DataFactory', ['$http', function($http){
    return {
        getArtists: function(){
            return $http.get('artists.json');   
        }
    }
}]);

}）;

findAll()

Answer 1

要获得支持，您必须显示定义DataFactory的代码！

在这里，我看到另一个错字：

expect(DataFactory.getArtists).toHaveBeenCalled();
expect(dataFactory.getArtists.callCount).toEqual(1); <-- DataFactory instead of dataFactory

Answer 2

您需要在测试中定义DataFactory。

这样做。

describe('Practice', function(){
 var ctrl;
 var DataFactory;

 beforeEach(module('MyApp'));
 beforeEach(inject(function($controller, _DataFactory_){
    DataFactory = _DataFactory_;
    spyOn(DataFactory, 'getArtists').andCallThrough();
    ctrl = $controller('ArtistCtrl', {
      DataFactory: DataFactory
    });   
}));

it('should have array available on load', function(){
    expect(DataFactory.getArtists).toHaveBeenCalled();
    expect(DataFactory.getArtists.callCount).toEqual(1);
});
