我试图为控制器编写一个单元测试,该控制器使用在控制器外定义的$ scope.action变量。
controller( "MyController", [
"$scope", "$window", "httpInterceptor",
function($scope, Service1, Service2, $window, httpInterceptor) {
$scope.init = function() { ... });
$scope.action.cb.write = function() { ... };
$scope.action.cb.read = function() { ... };
}]
);
我的单元测试如下。
describe("The controller", function () {
var $controller, $scope, httpInterceptor, window, httpBackend;
beforeEach(function() {
inject(function(_httpInterceptor_, _$controller_, _$rootScope_, $httpBackend, $http) {
$scope = _$rootScope_.$new();
httpInterceptor = _httpInterceptor_;
httpBackend = $httpBackend;
window = {setTimeout: function() {}};
$controller = _$controller_("MyController", {
httpInterceptor: _httpInterceptor_, $scope: $scope, $window: window, $http: $http
});})});
afterEach(function() {
httpBackend.verifyNoOutstandingExpectation();
httpBackend.verifyNoOutstandingRequest();
});
describe("The init() method", function () {
it("Init method", function () {
$scope.$parent.action = {}
$scope.init();
});});});
我收到错误TypeError: Cannot read property "cb" from undefined
。我很困惑为什么我得到这个错误,因为我试图只测试init函数。我最初尝试将$scope.$parent.action = {}
模仿$scope.action = {}
无效。
感谢。

因为在控制器获得"实例化"时引用了$scope.action
,所以在测试中分配它实际上太晚了,因为describe / it块在beforeEach / inject块之后运行完了。你应该在你的注入中初始化它。
inject(function(_httpInterceptor_, _$controller_, _$rootScope_, $httpBackend, $http) {
$scope = _$rootScope_.$new();
$scope.action = {};

在将$scope
属性注入测试中的控制器之前定义$scope = _$rootScope_.$new();
$scope.action = {'cb': {}};
属性:

Sheet("Sheet2").AutoFilter.ApplyFilter
ActiveWorkbook.Save
ThisWorkbook.Saved = True
End Sub
