我想我做的每件事都和教程中的一样,但有一个奇怪的错误。我想在我的 LoginService 中模拟 $http 并测试它。不幸的是,存在一些问题 - 看起来它没有看到 $httpBackend 函数。这是我的登录服务:
app.factory('LoginService', function($http) {
//..
var validateUser = function(username, password){
$http.post('http://domain/api/login',
{
username: username,
password: password
})
.success(function (data) {
//...
});
};
return {
validateUser: validateUser,
getLoginState: getLoginState
};
});
还有针对 validateUser 函数的测试:
describe('LoginService', function() {
var httpBackend, LoginService;
beforeEach(module('app'));
beforeEach(inject(function ($httpBackend, _LoginService_) {
LoginService = _LoginService_;
httpBackend = $httpBackend;
}));
afterEach(function() {
httpBackend.verifyNoOutstandingExpectation();
httpBackend.verifyNoOutstandingRequest();
});
it('changes loginState object when user exists', inject(function(){
data = {username: "ut_user", token: "123456"};
httpBackend.expectPOST('http://domain/api/login').respond(data);
LoginService.validateUser("user", "pass");
httpBackend.flush();
expect(LoginService.getLoginState().loggedIn).toBe(true);
}));
});
在 httpBackend.verifyNoOutstandingExpectation() 上有错误;和之前在 httpBackend.flush() 上:

我有业力 session :

'spec/**/*.js'

最佳答案
你的inject
不正确
beforeEach(inject(function ($httpBackend, _LoginService_) {
LoginService = _LoginService_;
httpBackend = $httpBackend;
}));
应该是
beforeEach(inject(function (_$httpBackend_, _LoginService_) {
LoginService = _LoginService_;
httpBackend = _$httpBackend_;
}));
关于angularjs - 在 Jasmine + Angular 中测试 $httpBackend,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/32653648/
