Question

下面是我的代码，我不想调用服务函数，所以我使用间谍，但它给出了错误。我无法弄明白。

'use strict';

describe('Testing DetailCtrl\n\n\n', function() {

  beforeEach(module("safe-repository"));

  var $controller, $scope, controller;
  var services = {
   documentService:null
  };

  // Initialization before tests
  beforeEach(inject(function(_$controller_, _documentService_){
    $controller = _$controller_;
    $scope = {};
    controller = $controller('DetailCtrl', { $scope: $scope });
    services.documentService=_documentService_;

    spyOn(services.documentService, 'deleteDocument').and.callFake(function(){
           console.log("inside delete function");
    });

  }));


  describe('Testing self.deleteFile() function for different test cases\n\n', function() {


    it(' When user has access permission to delete file/doc', function(done) {
        expect(services.documentService.deleteDocument).toHaveBeenCalled();
        // Inform jasmine that the test finish here
        done();
    });

  });


});

感谢任何帮助。

Answer 1

你不需要......

var services = {
   documentService:null
};

该代码只是令人困惑。

你应该将其简化为......

// services.documentService=_documentService_; // WHY DO THIS??
documentService=_documentService_;

然后......

spyOn(documentService, 'deleteDocument').and.callFake ... etc

然后......

expect(documentService.deleteDocument).toHaveBeenCalled();

你可能也想尝试......

spyOn(loginService, 'isSuperAdmin').and.returnValue("something");

INSTEAD OF callFake（你的期望陈述将保持不变）

另外......

我假设您的控制器在构建期间正在调用此方法？例如，以下行在施工期间进行预期的呼叫？

 controller = $controller('DetailCtrl', { $scope: $scope });

换句话说，你的控制器应该看起来像......

app.controller("DetailCtrl", function($scope, documentService) {
    // some other code
    documentService.deleteDocument(); // MAKE SURE THIS CODE IS ACTUALLY BEING HIT IF ITS WRAPPED IN A CONDITIONAL STATEMENT
    // some other code
});

试试这个，它可能对你有所帮助:)。

'use strict';

describe('Testing DetailCtrl\n\n\n', function() {

var $controller, scope, ctrl, mockService;

beforeEach(module("safe-repository"));

beforeEach(inject(function($rootScope, _$controller_){
 scope = $rootScope.$new();
 function del() {
    //your return value
 }
 mockService = {
   deleteDocument: del
 }
 $controller = _$controller_;
 }));

 function initController(){
   ctrl = $controller('DetailCtrl', {
    $scope: scope,
    documentService: mockService
   });
 }


 it(' When user has access permission to delete file/doc', function() {
     spyOn(documentService,'deleteDocument').and.callThrough();
     initController();
     expect(mockService.deleteDocument).toHaveBeenCalled();
 });

});


});
