我有以下情况:
controller.js
controller('PublishersCtrl',['$scope','APIService','$timeout', function($scope,APIService,$timeout) {
APIService.get_publisher_list().then(function(data){
});
}));
controllerSpec.js
'use strict';
describe('controllers', function(){
var scope, ctrl, timeout;
beforeEach(module('controllers'));
beforeEach(inject(function($rootScope, $controller) {
scope = $rootScope.$new(); // this is what you missed out
timeout = {};
controller = $controller('PublishersCtrl', {
$scope: scope,
APIService: APIService,
$timeout: timeout
});
}));
it('should have scope variable equals number', function() {
expect(scope.number).toBe(3);
});
});
错误:
TypeError: Object #<Object> has no method 'get_publisher_list'
我也尝试过类似的东西,但它不起作用:
describe('controllers', function(){
var scope, ctrl, timeout,APIService;
beforeEach(module('controllers'));
beforeEach(module(function($provide) {
var service = {
get_publisher_list: function () {
return true;
}
};
$provide.value('APIService', service);
}));
beforeEach(inject(function($rootScope, $controller) {
scope = $rootScope.$new();
timeout = {};
controller = $controller('PublishersCtrl', {
$scope: scope,
APIService: APIService,
$timeout: timeout
}
);
}));
it('should have scope variable equals number', function() {
spyOn(service, 'APIService');
scope.get_publisher_list();
expect(scope.number).toBe(3);
});
});
我该如何解决这个问题?有什么建议吗?
答案 0 :(得分:37)
有两种方式(或更多肯定)。
想象一下这种服务(如果是工厂的话无关紧要):
app.service('foo', function() {
this.fn = function() {
return "Foo";
};
});
使用此控制器:
app.controller('MainCtrl', function($scope, foo) {
$scope.bar = foo.fn();
});
一种方法是使用您将使用的方法创建一个对象并监视它们:
foo = {
fn: function() {}
};
spyOn(foo, 'fn').andReturn("Foo");
然后将foo
作为dep传递给控制器。无需注入服务。这将有效。
另一种方法是模拟服务并注入模拟的服务:
beforeEach(module('app', function($provide) {
var foo = {
fn: function() {}
};
spyOn(foo, 'fn').andReturn('Foo');
$provide.value('foo', foo);
}));
当您注射foo
时,它会注入这个。

对于那些努力使答案有效的人,
自Jasmine 2.0 andReturn()
成为and.returnValue()
例如,在上面的plunker的第一次测试中:
describe('controller: MainCtrl', function() {
var ctrl, foo, $scope;
beforeEach(module('app'));
beforeEach(inject(function($rootScope, $controller) {
foo = {
fn: function() {}
};
spyOn(foo, 'fn').and.returnValue("Foo"); // <----------- HERE
$scope = $rootScope.$new();
ctrl = $controller('MainCtrl', {$scope: $scope , foo: foo });
}));
it('Should call foo fn', function() {
expect($scope.bar).toBe('Foo');
});
});
