我有这样的功能
$scope.openMail=function(mail){
DocumentTypes.getDocument(function(response){
$scope.documentTypes=response.result;
$log.log("documentTypes",$scope.documentTypes);
})
}
以上乐趣的规格是
it("should test open mail",function(){
scope.documentTypes=[{"type":"pdf"},{"type":"xml"}];
spyOn(documentTypes,"getDocument").and.callFake(function(){
return scope.documentTypes;
});
var mail='back';
scope.openMail(mail);
expect(scope.documentTypes).toEqual({"type":"pdf"},{"type":"xml"});
})
解决方法
您的测试有几个问题：
>你做spyOn(documentTypes,“getDocument”)而不是spyOn(DocumentTypes,“getDocument”)
>你的假函数返回一个值(同步)而不是调用提供的回调(异步)
>首先将scope.documentTypes初始化为测试的预期结果,即无论代码做什么,测试都会通过(除非你得到例外)
>更多代码问题 – 您正在测试的函数对输入邮件参数没有任何作用
这是我将如何测试它：
describe('$scope.openMail',function() {
beforeEach(function() {
spyOn(DocumentTypes,'getDocument');
});
it('uses DocumentTypes.getDocument service to get the document types',function() {
$scope.openMail('test_mail');
expect(DocumentTypes.getDocument).toHaveBeenCalledWith(jasmine.any(Function));
});
describe('provides a callback function that',function() {
beforeEach(function() {
DocumentTypes.getDocument.and.callFake(function (callback) {
callback('test_document_types');
});
});
it('stores the document types on the scope',function() {
$scope.openMail('test_mail');
expect($scope.documentTypes).toEqual('test_document_types');
});
// Note: This is optional,depending on whether you test logging or not
it('logs the document types',function() {
spyOn($log,'log');
$scope.openMail('test_mail');
expect($log.log).toHaveBeenCalledWith('documentTypes','test_document_types');
});
});
});
