AngularJSUnitTesting:预期已调用spy函数（）

下面是我的代码，我不想调用服务函数，所以我使用的是spy，但它给出了错误。我无法找出它

'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();
    });

  });


});

感谢您的帮助

你不需要

var services = {
   documentService:null
};

那个代码只是把事情弄糊涂了

你应该把它简化为

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

然后

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

expect(documentService.deleteDocument).toHaveBeenCalled();

然后

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

expect(documentService.deleteDocument).toHaveBeenCalled();

你可能也想试试

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

而不是callFake（您的expect语句将保持不变）

还有

我假设您的控制器在构造期间正在对该方法进行预期调用？e、 g以下线路在施工期间发出预期呼叫

 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，它可能会帮助您：）

您是否真的在任何地方调用了

services.documentService.deleteDocument（）

？我不确定，但是的，我想调用services.documentService.deleteDocument（），并将其模拟为testYeah刚才我观察到，我认为调用没有发生在服务内部，我在注入或分配过程中犯了什么错误
