我正在尝试创建单元测试来测试导航列表控制器，但我在创建测试时遇到了问题。
这是控制器的代码。
navListModule.controller('NavListCtrl', ['$scope', 'NavList',
function ($scope, NavList) {
$scope.$on('$routeChangeSuccess', function (event, routeData) {
var stationId = routeData.params.stationId;
if ((stationId !== null) && (stationId !== undefined)) {
$scope.stationId = stationId;
var navList = NavList;
$scope.menuOptions = navList.getMenuOptions(stationId);
}
});
}
]);
到目前为止，这是我在单元测试中提出的。
'use strict';
describe('unit testing navListModule', function () {
var scope, ctrl, location;
describe('test NavListCtrl', function () {
beforeEach(module('shipApp.navListModule'));
// mock NavListService for testing purposes
var mockNavListService = {
getMenuOptions: function (stationId) {
// set default menu options
var menuOptions = [
{
name: "Alerts"
, pageURL: "alerts"
}
, {
name: "Reports"
, pageURL: "reports"
}
, {
name: "Run Close Outs"
, pageURL: "closeOuts"
}
];
// add admin menu option if stationId set to Admin
if (stationId.toUpperCase() == 'Admin'.toUpperCase()) {
menuOptions.push(
{
name: "Admin"
, pageURL: "admin"
}
);
}
return menuOptions;
}
};
beforeEach(inject(function ($rootScope, $controller, $location) {
scope = $rootScope.$new();
ctrl = $controller('NavListCtrl', { $scope: scope, NavList: mockNavListService });
location = $location;
}));
it('should expect stationId to be undefined if stationId not defined in route parameters', function () {
expect(scope.stationId).toBeUndefined();
});
it('should expect scope.$on not to be called if no change in route', function () {
spyOn(scope, '$on');
expect(scope.$on).not.toHaveBeenCalled();
});
it('should expect scope.$on to be called on change in route', function () {
spyOn(scope, '$on');
scope.$on('$routeChangeSuccess', function (event, routeData) {});
expect(scope.$on).toHaveBeenCalled();
});
it('should expect stationId to be defined in route parameters if route is #/:stationId/path', inject(function ($routeParams) {
location.path('/Admin/alerts');
var locationElements = location.path().substring(location.path().indexOf('/') + 1).split('/');
var stationId = locationElements[0];
$routeParams.stationId = stationId;
expect($routeParams.stationId).toEqual('Admin');
}));
it('should expect menuOptions array to be returned when getMenuOptions function is called', function () {
var stationId = 'Admin';
var menuOptions = NavListCtrl.getMenuOptions(stationId);
});
});
});
我只是在学习 Angular，所以我不确定我是否正确设置了我的测试。我是否应该创建测试以确保控制器逻辑在 $routeChangeSuccess 事件发生之前不会发生？如果是这样，我该如何编写这样的测试？另外，测试 getMenuOptions 调用（最后一次测试）的正确方法是什么？请让我知道测试此控制器的正确方法。
在此先感谢，肖恩
在玩了一些测试和 jvandemo 的帮助之后，这是我为控制器以及底层服务的单元测试提出的。如果我做错了什么，请告诉我。
