Standalone Mocking In .Net 4.0 MVC?
Jun 21, 2010I'm trying to unit test the logOn method of my .Net 4.0 MVC application. I'm pretty sure I need to mock a bunch of objects because I don't want to hit the actual database and I only want to simulate an HTTPcontext in a limited and specific way (if I have to do it at all). All the examples I've found online use mocking frameworks like Moq, RinoMocks or nMock. MVC is all about Test Driven Development, there must be some way to do simple tests without using third party software.
The specific problem,The basic problem is that the controller I'm testing calls Response.Cookies.Add(...) but since the unit test is not in an HTTPContext, Response is null and I get an exception.
My research so far,I understand there is a layer of abstraction which will help me somehow. For example HttpResponse inherits from HttpResponseBase. I think I'm supposed to make a class that inherits from one of the MVC base classes, overload some of the members and then
call the method I want to test in a way that gives it my object instead of one it would normally use.
The question is how to do that. One would need to set up existing code with the ability to construct future versions of objects. Intuitively however, it would seem that existing code could only be and use functionality that existed at the time it was written.
Fortunately, a dynamic runtime means that the code which is actually run can be determined things that change after it is written like config files and HTTP headers.
One way to do that is for the existing code to use some method typically referred to as a factory that takes a string and returns an instance of an object.I conclude that I should look through the code for this factory and figure out how to manipulate it.
My background,I've recently graduated with a degree in Computer Science. Now at my new job, I've been assigned to write unit tests for a large project. Admittedly, I'm new to MVC, many aspects of C# and large projects in general. I may have made simple mistakes or incorrect assumptions in my analysis of this problem. I will do my best to stay active on this post and make it useful for others in situations similar to mine.

Mocking User.Identity In .NET MVC?
Jun 12, 2010I need to create Unit Tests for an ASP.NET MVC 2.0 web site. The site uses Windows Authentication.I've been reading up on the necessity to mock the HTTP context for code that deals with the HttpContext. I feel like I'm starting to get a handle on the DI pattern as well. (Give the class an attribute of type IRepository and then pass in a Repository object when you instantiate the controller.)
What I don't understand, however, is the proper way to Mock the Windows Principal object available through User.Identity. Is this part of the HttpContext? have a link to an article that demonstrates this (or a recommendation for a book)?
What Advantages Does PHP
Oct 21, 2010I have opened a large web project on elance for a social network. I got over 30 bids on my project and many of the providers recommended php even though they had .net knowledge. many have said that php with drupal has many advanteges over the .NET framework but did not say what they were. Its hard to believe that a scripting language has advantages over a compiled language.

May 25, 2010I'll be starting a complete re-write of a system in the coming weeks. I'll be using ASP.NET MVC 2.I'm still trying to determine what I should be using as far as TDD, mocking, and IOC is concerned. I was thinking:
VSTEST for writing my TDD tests (or possibly nUnit) Moq as my mocking framework (for creating doubles and fakes) Moq for IOC development Not sure exactly what the ideal setup should be and I'm continuing to research what's available. I'd like some feedback from the community on the most optimal toolsets for TDD, mocking, and IOC.
Looking For Complete Mocking Framework For HttpContext?
Aug 25, 2010I'm looking for as comprehensive as possible of a mock replacement and wrapper for the ASP.NET HttpContext in my applications. A comprehensive mock replacement could potentially increase the testability of my ASP.NET web applications substantially, without necessitating migrating every application to more-testable frameworks such as MVC.
Some of the features I am most interested in seeing in an HttpContext wrapper and mock framework include:
Serialized session storage (e.g., .Session).
Serialized application-scoped storage (e.g., .Application).
Per-request item storage (e.g., .Items).
HttpRequest data, such as referrers, request Uri, server variables, post data, etc.
HttpResponse data, such as status codes and content.
Local file resolution (e.g. Server.MapPath)
VirtualPathUtility for application-relative URL path resolution, which has a dependency on the ASP.NET runtime.The identity and principal (e.g., .User) for validating authentication/authorization rules.The AllErrors collection for testing error resolution in HttpModules and Global.asax.I considered writing my own interface, wrapper, and mock; however, I believe such must already exist. The variety of mock frameworks is a little overwhelming for a first-timer to absorb.
What is the most comprehensive HttpContext wrapper and mock?

View 1 RepliesWhat's The Advantages Of The Open Id
Jan 3, 2011The first time i use the Open ID was in my favorite site stackoverflow , i like it so much, from this time to now, i have a set of questions about it: What are the advantages of the open id ?is it just a login facility(more usable than the usual process of entering user name and password)?(i think it will confuse users who are not know them)
Is the open id more secured or less secured or it doesn't related to the security issue at all? Why not all web sites (i mean the popular) use it?Is the implementation is that difficult? When to use open id in a web site? Is it considered as an alternative to the login control or not? if i want to to use the open id in my web application? What is the start point?What are the steps to begin ? Is it a big issue or i can use it in my web application?

View 1 RepliesSignificant Advantages Of MVC?
Jul 30, 2010I'm slowly getting into MVC, but it's still relatively new to me. From what I've discovered by doing a few tutorials, MVC provides an interface for communication between the database and the website and in general allows for better organization of the code. Are there other significant advantages to using an MVC structure? What would be an example of a time when you wouldn't want to user MVC, even if you are communicating with a database?

Advantages/Disadvantages Of Public Shared Functions
Jan 8, 2010We have an application that has quite an extensive APP_Code directory (about 150 functions). The functions are split across multiple files and then classes and namespaces.
On numerous pages we have to create numerous instances of the classes to be able to access the functionality, which can get very repetitive and means we're repeating code on every page declaring the instance etc.
As far as I can tell, a way to navigate this issue, is to make the functions Public Shared (as opposed to just Public functions).
