我试图用Angular围绕单元测试,我遇到了一些路障。尝试为此问题创建一个plnkr:Jasmine test fails making $httpbackend call我遇到了不同的错误。我希望如果有人可以帮助找出这个问题,那么这将有助于解决原始问题:http://plnkr.co/edit/lJTx0ldR9nEnlYbU5pJd

有几件事:
在respond
response
代替$httpBackend.expectPOST
data
参数隐藏在$http.success
处理程序中 - 将其重命名为postData
。也将期望的对象传递给成功回调。
var _postData = function(url, params, data, successFunction /* ... */) {
//...
$http( {
method: 'POST',
url: url,
params: params,
data: data,
cache: false
} )
.success( function ( postData, status, headers, config ) {
// ...
successFunction({
success: true,
user: data
}, status, headers, config);
} );
//...
}
LoginController
返回的对象只能通过$scope.model.user = response.user;
等显式引用进行更改 - 只需调用_user = response.user
即可更改$scope.model.user
,除非您换{封闭中的{1}}。
