Question

我用jasmine测试了我的javascript代码但是当我看到我的jenkins单元测试覆盖率时，我有一些未标记为绿色的行（未经测试）。所以这就是为什么我问我的问题：

- ＆GT;假设tagStyle.length = 0

                $scope.isTagStylesNotEmpty = function() {
                    if($scope.tagStyles.length >= 0) /* This line is RED (not covered ) */
                    {
                            return true;/* This line is Green OK*/
                    }
                }

- ＆GT;我的测试如下：

  it('Unit test isTagStylesNotEmpty()', inject(function($httpBackend) {
    expect($scope.isTagStylesNotEmpty).toBeDefined();
    $scope.isTagStylesNotEmpty();
    expect($scope.tagStyles.length).toBe(0);
    }));

关于这一点的任何想法？

第二个问题与第一个问题相同，但有点复杂：

我有以下Javascript文件，我想用jasmine进行单元测试：

    $scope.ajouterProfilTag = function(lastDocId) {

    $scope.tagStyles.forEach(function(item) {
                   /*Not covered from here (by jenkins )--------------------*/
        var profilTag = {
            tag: item.id_tag,
            texte: item.style,
            profil: lastDocId,
            tagName: item.label,
            police:  item.police,
            taille: item.taille,
            interligne: item.interligne ,
            styleValue: item.styleValue,
        };

        $http.post('/ajouterProfilTag', profilTag)
            .success(function(data) {

                $scope.profilTagFlag = data; /* unit tests */
                $scope.afficherProfils();
                $scope.profilTag = {};
                $scope.tagStyles.length = 0;
                $scope.tagStyles = [];
            /*Until here --------------------*/
        });

    });

    $scope.tagList = {};
    $scope.policeList = {};
    $scope.tailleList = {};
    $scope.interligneList = {};
    $scope.weightList = {};

};

我的单元测试是这样的：

 var profil = {
    _id: "52d8f928548367ee2d000006",
    photo: "./files/profilImage.jpg",
    descriptif: "descriptif3",
    niveauScolaire: "CM2",
    type: "Dyslexie N2",
    nom: "Nom3"
  };



    var profilTag = {
        _id: "52d8f928548367ee2d000006",
        tag: "tag",
        texte: "texte",
        profil: "profil",
        tagName: "tagName",
        police: "Arial",
        taille: "eight",
        interligne: "fourteen",
        styleValue: "Bold"
      }

    beforeEach(inject(function($controller, $rootScope, $httpBackend) {
        $scope = $rootScope.$new();
        controller = $controller('ProfilesCtrl', {
          $scope: $scope
        });


        $httpBackend.whenPOST('/ajouterProfilTag').respond(profilTag);



      }));

      it('ProfilesCtrl:ajouterProfilTag should set ajouterProfilTag function', inject(function($httpBackend) {
         expect($scope.ajouterProfilTag).toBeDefined();
         $scope.ajouterProfilTag(profil._id);
          $httpBackend.flush();
          expect($scope.profilTagFlag).toEqual(profilTag);

      }));

Anyh关于如何对第二种方法（AjouterProfilTag）进行单元测试的想法？提前谢谢

只是一个猜测，因为我没有看到控制器，但似乎$ scope.tagStyles只是一个空对象。这意味着forEach将无需迭代，因此它永远不会调用帖子。我会尝试类似的东西：

$scope.tagStyles = [{}];

前

$scope.ajouterProfilTag(profil._id);
