Question

使用Angular.js，Mocha和Jasmine进行测试我对DeviceVal值文件进行了测试：

describe("load balancer device: value", function() {
  var DeviceVal;
  DeviceVal = null;
  beforeEach(function() {
    return module("main.loadbalancer");
  });
  beforeEach(inject(function(_DeviceVal_) {
    return DeviceVal = _DeviceVal_;
  }));
  return it("should default the id to 'device not loaded'", function() {
    return expect(DeviceVal).toEqual({
      readonly: false,
      lb: "device not loaded"
    });
  });
});

对于我的其他测试之一，我使用了DeviceVal值文件：

describe("load balancer controller: readonly", function() {
  $scope = DeviceVal = LoadBalancerSvc = SearchSvc = $state = $sce = null;

  beforeEach(function() {
    module('main');
  });

  beforeEach(inject(function($controller, $rootScope, _$state_, _LoadBalancerSvc_, _DeviceVal_) {
    $scope = $rootScope.$new();
    $state = _$state_;
    LoadBalancerSvc = _LoadBalancerSvc_;
    DeviceVal = _DeviceVal_;

    $controller('HeaderCtrl', {$scope: $scope});
    //to resolve all the promises we have on the mocked service
    $scope.$digest();
    lb = { ha_status: "secondary", id: "34584"};
    this.lb = lb;
    spyOn(LoadBalancerSvc, "searchDevice").and.returnValue(
      {get: function() {
          return { then: function(fn) { fn(lb)} }}});
    spyOn($state, "go");
  }));

  it('scope data memembers to have their stuff', function() {
    $scope.searchButton.submit();
    expect(lb).toEqual(this.lb);
    expect(lb['ha_status']).toEqual("secondary");
    expect(DeviceVal.readonly).toBe(true);
    expect($state.go).toHaveBeenCalledWith("main.loadbalancer.vips", {id: this.lb.id});
    });
});

我遇到的问题是我想手动将DeviceVal的第二次测试中的值设置为自定义值。但相反，测试期望值为第一个DeviceVal测试文件中的值。它抱怨说：

Expected { readonly : true, lb : { ha_status : 'secondary', id : '34584' } } to equal { readonly : false, lb : 'device not loaded' }.

如何进行第二次测试，我可以手动设置值DeviceVal.lb = { ha_status: "secondary", id: "34584"};并拥有expect(lb['ha_status']).toEqual("secondary");和expect(DeviceVal.readonly).toBe(true);？

更新：

这是模拟DeviceVal，但我仍然得到Error: Expected { readonly : true, lb : { ha_status : 'secondary', id : '34584' } } to equal { readonly : fals e, lb : 'device not loaded' }.：

describe("load balancer controller: readonly", function() {
  $scope = DeviceVal = LoadBalancerSvc = SearchSvc = $state = $sce = null;

  beforeEach(function() {
    module('main');
  });

  beforeEach(inject(function($controller, $rootScope, _$state_, _LoadBalancerSvc_, _DeviceVal_) {
    $scope = $rootScope.$new();
    $state = _$state_;
    LoadBalancerSvc = _LoadBalancerSvc_;
    DeviceVal = _DeviceVal_;

    $controller('HeaderCtrl', {$scope: $scope});
    //to resolve all the promises we have on the mocked service
    $scope.$digest();

    //MY ATTEMPT AT MOCKING THIS DATA
    DeviceVal.lb = { ha_status: "secondary", id: "34584"};
    DeviceVal.readonly = true;

    spyOn(LoadBalancerSvc, "searchDevice").and.returnValue(
      {get: function() {
          return { then: function(fn) { fn(DeviceVal.lb)} }}});
    spyOn($state, "go");
  }));

  it('scope data memembers to have their stuff', function() {
    $scope.searchButton.submit();
    expect(DeviceVal.lb).toEqual({ha_status: "secondary", id: "34584"});
    expect(DeviceVal.lb['ha_status']).toEqual("secondary");
    expect(DeviceVal.readonly).toBe(true);
    expect($state.go).toHaveBeenCalledWith("main.loadbalancer.vips", {id: DeviceVal.lb.id});
    });
});

修正了它。从http://angular-tips.com/blog/2014/06/introduction-to-unit-test-controllers/开始，我创建了这样的模拟数据：

describe("load balancer controller: readonly", function() {
  $scope = DeviceVal = LoadBalancerSvc = SearchSvc = $state = $sce = null;

  beforeEach(function() {

    eviceVal = {}
    module('main', function($provide) {
      $provide.value('DeviceVal', eviceVal);
    });

    inject(function() {
      eviceVal.lb = { ha_status: "secondary", id: "34584"};
      eviceVal.readonly = true;
    });
  });
