c# - Unit Testing using Moq -


this method under controller used create dummy keys encrypt data in application , store same in amazon s3 bucket.

public jsonresult savemasterkeys(string mektext, int thismek)         {             string foldername = string.empty, filename = string.empty;             list<string> foldernamelist = new list<string>();             foldernamelist.add("guard1");             foldernamelist.add("guard2");             try             {                 if (thismek == 1)                 {                     foldername = "guard1";                     filename = "newmek1.key";                 }                 else                 {                     foldername = "guard2";                     filename = "newmek2.key";                 }                 awss3file aws = new awss3file();                  //aws.bucketexist(filepath);                 //aws.createfile(mektext, filepath);                 // check weather folder exist or not                  if (!aws.checkfolderexist(foldername))                 {                     foreach (var item in foldernamelist)                     {                         aws.createfolder(item);                         if (item == "guard1")                         {                             aws.createfileintos3((item == foldername ? mektext : ""), item, "newmek1.key");                             aws.createfileintos3("", item, "mek1.key");                         }                         else                         {                             aws.createfileintos3((item == foldername ? mektext : ""), item, "newmek2.key");                             aws.createfileintos3("", item, "mek2.key");                         }                     }                 }                 else                 {                     aws.createfileintos3(mektext, foldername, filename);                 }                 viewdata["savemessage"] = "saved successfully.";             }             catch (exception ex)             {                 xtp.logger.logcritical("xtp.web.internaltools", ex.tostring());                 viewdata["savemessage"] = "keys not updated successfully.";             }             return json(new { success = true, value = viewdata["savemessage"] }, jsonrequestbehavior.allowget);         }

and testmethod have written same

[testmethod]         public void mockalways()         {             var mock = new mock<accountcontroller>();             jsonresult json = new jsonresult();             //new { success = true, value = viewdata["savemessage"] }, jsonrequestbehavior.allowget             json.data = new { success = true, value = "sa" };             json.jsonrequestbehavior = jsonrequestbehavior.allowget;               mock.setup(x => x.savemasterkeys("ss", 1)).returns(json);              var controller = new accountcontroller();             var result = controller.savemasterkeys("ss", 1) jsonresult;              assert.areequal(mock.object.savemasterkeys("ssxs", 1), result.data.tostring());         }

i getting invalid setup error. there way resolve error?

i think misunderstood how mock controller's action. mocking , comparing mocked controller. not way go(it checking whether true == true.

basically error means moq cannot override non-virtual member(it self-explanatory). should change method's signature virtual allow overriding it.

but - shouldn't mock action this. instead should mock dependencies(services, contexts, gateways etc.) , check whether known input values can expected results without mocking action itself.

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
