Question

我有以下问题：我无法从angularjs单元测试文件中访问控制器中对象 textes 的属性文本：

$scope.ocr = function(source) {

    initialiseZones();

    $http.post("/oceriser", {
        sourceImage: source
    }).success(function(data, status, headers, config) {

        $scope.textes = {
            source: source,
            editor: $scope.addEditor(angular.fromJson(data)),
            text: angular.fromJson(data)
        };


        $scope.currentImage.source = "";

        $scope.showEditor = true;

        $scope.msg = "ok";
    }).error(function(data, status, headers, config) {
        $scope.msg = "ko";
    });
}

在我的测试文件中，我想测试我的控制器方法，所以我执行以下操作：

it('has to return text from image', inject(function($httpBackend) {

     var expected = {text : 'blabla'}; 

     $httpBackend.expectPOST('/oceriser').respond(expected);

     $scope.ocr('./image.png');

     $httpBackend.flush();

        expect($scope.textes.text).toBe(expected.text); // this line has to be false because the value of $scope.textes.text is different from expected.text value. 
        expect($scope.textes.source).toBe('./image.png');// this line is true and when the parameter of the matcher is changed it becomes false

}));

问题是我访问的值（$ scope.textes.source是正确的./image.png）但值$ scope.textes.text不正确并且与expected.text

我不知道有什么问题会出现什么问题？建议？

尝试在$scope.$digest()：

之后致电$httpBackend.flush();

it('has to return text from image', inject(function($httpBackend) {
     var expected = {text : 'blabla'}; 
     $httpBackend.expectPOST('/oceriser').respond(expected);
     $scope.ocr('./image.png');
     $httpBackend.flush();
     $scope.$digest(); //here
     expect($scope.textes.text).toBe(expected.text); // this line has to be false because the value of $scope.textes.text is different from expected.text value. 
     expect($scope.textes.source).toBe('./image.png');// this line is true and when the parameter of the matcher is changed it becomes false
}));

这是为了在http调用之后触发$scope同步 =＆GT;手动测试，自动生产运行。
