我不能得到的测试结果通过我使用了一个非常基本的实现来理解测试更深。
我有一个工厂,返回一个承诺,从我的控制器访问。 我想测试呼叫成功并分配到的响应repos
变种。 以下是代码:
'use strict';
angular.module('app')
.factory('searchServ', function ($timeout, $q, $http) {
return {
fetch: function(user) {
var deferred = $q.defer();
$timeout(function(){
$http({method: 'GET', url: 'https://api.github.com/users/' + user + '/repos'}).then(function(repos) {
deferred.resolve(repos.data);
}, function(reason){
deferred.reject(reason.status);
console.log(reason);
});
}, 30);
return deferred.promise;
}
};
})
.controller('MainCtrl', function ($scope, searchServ) {
$scope.results = function(user) {
$scope.message = '';
searchServ.fetch(user).then(function (repos) {
if(repos.length){
$scope.message = '';
$scope.repos = repos;
}
else{
$scope.message = 'not found'
}
}, function (){
$scope.message = 'not found';
});
};
});
//Test
'use strict';
describe('MainCtrl', function () {
var scope, searchServ, controller, deferred, repos = [{name: 'test'}];
// load the controller's module
beforeEach(module('app'));
beforeEach(inject(function($controller, $rootScope, $q) {
searchServ = {
fetch: function () {
deferred = $q.defer();
return deferred.promise;
}
};
spyOn(searchServ, 'fetch').andCallThrough();
scope = $rootScope.$new();
controller = $controller('MainCtrl', {
$scope: scope,
fetchGithub: fetchGithub
});
}));
it('should test', function () {
expect(scope.test).toEqual('ha');
});
it('should bind to scope', function () {
scope.results();
scope.$digest();
expect(scope.message).toEqual('');
//expect(scope.repos).not.toBe(undefined);
});
});
运行这个测试给我下面的错误:
TypeError: undefined is not a function (evaluating 'spyOn(searchServ, 'fetch').andCallThrough()') in test/spec/controllers/main.js (line 15)
任何想法如何测试这个使得其测试范围的结合,以及异步调用?
