    <p>I am writing unit test for this method. I have tried lot of times but still can not write any code for it. Please suggest me how to unit test it. I am using C# , nunit framework and rhino mock.</p> <p>Thanks in advance.</p> <pre><code> public FileUploadJsonResult AjaxUploadProfile(int id, string branchName, string filepath, HttpPostedFileBase file) { // TODO: Add your business logic here and/or save the file string statusCode = "1"; string profilePicture = string.Empty; string fileExtension = System.IO.Path.GetExtension(file.FileName.ToLower()); string fileName = id + "_" + branchName; string fileNameWithOriginalExtension = fileName + fileExtension; string fileNameWithJPGExtension = fileName + ".jpg"; string fileServerPath = this.Server.MapPath("~/LO_ProfilePicture/" + fileNameWithJPGExtension); string statusMessage = string.Empty; if (string.IsNullOrEmpty(fileExtension) || !Utility.isCorrectExtension(fileExtension)) { statusMessage = "Profile picture should be of JPG, BMP, PNG, GIF or JPEG format."; return new FileUploadJsonResult { Data = new { message = string.Format(statusMessage, fileNameWithOriginalExtension), filename = string.Empty, profilepic = profilePicture, statusCode = "0" } }; } if (file.ContentLength &gt; PageConstants.PROFILE_PICTURE_FILE_SIZE) { statusMessage = "Profile picture size should be less than 2MB"; return new FileUploadJsonResult { Data = new { message = string.Format(statusMessage, fileNameWithOriginalExtension), filename = string.Empty, profilepic = profilePicture, statusCode = "0" } }; } Utility.SaveThumbnailImage(fileServerPath, file.InputStream, PageConstants.BRANCH_PROFILE_PICTURE_FILE_HEIGTH, PageConstants.BRANCH_PROFILE_PICTURE_FILE_WIDTH); profilePicture = PageConstants.IMAGE_PATH + "LO_ProfilePicture/" + fileNameWithJPGExtension; // Return JSON return new FileUploadJsonResult { Data = new { message = string.Format("Profile Picture is successfully uploaded.", fileNameWithOriginalExtension), filename = fileNameWithJPGExtension, profilepic = profilePicture, statusCode } }; } </code></pre>

    1. CONot every method can be unit tested. If you can break out the non-Json logic (e.g. the decision tree based on the extension/content length. then unit test _that_ and keep the Json part small.

    2. COI'd delete all the code and start fresh. I'd wager decent money you wouldn't write anything near this bad if you were using TDD.

    3. CO@DStanley I disagree that not every method can be unit tested. If it is not unit testable, then your code is most likely breaking the SRP and needs refactored so that it can be unit testable

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
