I want to unit test my asp.net web application using NUnit.
For this I have downloaded and installed NUnit from internet.
But since I am new to this tool , I am looking for documentation about this tool.
How can I use this tool for testing web applications? give me links to documentation?
Also is it possible to integrate NUnit with visual studio, if yes, how?
This is my first test for Asp.Net Web Application. We have an Engine consisting of several modules. I need to test classes in Engine Module. Though these clases are part of Asp.Net App, they consists of only business logic. How can I test these classes in isolation other being part of WebApp ? because i am getting this error
The Web request 'http://localhost:8936/' completed successfully without running the test. This can occur when configuring the Web application for testing fails (an ASP.NET server error occurs when processing the request), or when no ASP.NET page is executed (the URL may point to an HTML page, a Web service, or a directory listing). Running tests in ASP.NET requires the URL to resolve to an ASP.NET page and for the page to execute properly up to the Load event. The response from the request is stored in the file 'WebRequestResponse_BlogManagerBPOConstr.html' with the test results; typically this file can be opened with a Web browser to view its contents.

What is the best way to unit test the presentation layer of a web forms application? I have been told that there are frameworks available like Watin. Are there better tools around?
View 1 RepliesMy que is why use NUnit if VS2008 has built in Unit Testing
In my company app they are uing NUnit and I am wondering why. Now VS2008 has built in Unit Testing so why to use NUnit?
I've just downloaded NUNit and would like it to be an option for my Test Project provider when I create a new MVC 2 application. At the moment the only option I am getting is the Visual Studio (MSTest) option.
View 2 RepliesI'm currently trying to upgrade our build server at work, going from having no build server to having one!
I'm using JetBrains' TeamCity (having used ReSharper for a couple of years I trust their stuff), and intend to use NUnit and MSBuild.
However, I've come up with an issue: it appears that it is not possible to test an ASP.NET web site with NUnit. I had assumed it would be possible to configure it to test App_Code after a build, however it seems that the only way to do tests nicely is through converting the web site to a web application
How could I go about this? the testing needs to be able to be fired automatically from TeamCity.
Im pretty new to MVC and have never tried unittesting before, so i bought "Pro ASP.NET MVC2 Framework" by Steve Sanderson. I have installed Nunit but when i am trying to open my test class in the nunit GUI i get this error message Visual Studio 2010 > Projects > SportsStore > SportsStore.UnitTests > Bin > Debug > SportsStore.UnitTests.dll "This assembly was not built with any known testing framework"
View 6 RepliesI'm using VSTS 2K8 and I've set up a Unit Test Project. In it, I have a test class with a method that does a simple assertion. I'm using an Excel 2007 spreadsheet as my data source.
My test method looks like this:
[Code]....
As indicated in the method decoration attributes, my Excel spreadsheet is on my local C:/ Drive. In it, the sheet where all of my data is located is named "Sheet1".I've copied the Excel spreadsheet into my project and I've set its Build Action = "Content" and I've set its Copy to Output Directory = "Copy if Newer".
When trying to run this simple unit test, I receive the following error:
The unit test adapter failed to connect to the data source or to read the data. For more information on troubleshooting this error, see "Troubleshooting Data-Driven Unit Tests" (http://go.microsoft.com/fwlink/?LinkId=62412) in the MSDN Library. Error details: ERROR [42S02] [Microsoft][ODBC Excel Driver] The Microsoft Office Access database engine could not find the object 'Sheet1'. Make sure the object exists and that you spell its name and the path name correctly.
I've verified that the sheet name is spelled correctly (i.e. Sheet1) and I've verified that my data sources are set correctly.Web searches haven't turned up much at all.

I created my testing project by just adding a class library and referencing nunit dll. Works fine.However, I'm curious as to how get NUnit integrating with VS2010 just like MS Unit.Also any good reading on TDD with MVC 2 (like specific to the new functionality available in MVC 2)?

I'm trying to unit test the MembershipProvider, however I cant figure out how or whether there is any need for unit testing of it...
My business layer:
public interface IAccountService
{
MembershipCreateStatus CreateUser(string userName, string password, string email);
}
public class AccountService : IAccountService
{
private readonly MembershipProvider provider;
public AccountService() : this(null) { }
public AccountService(MembershipProvider providera)
{
this.provider = providera ?? Membership.Provider;
}
public MembershipCreateStatus CreateUser(string userName, string password, string email)
{
if (String.IsNullOrEmpty(userName)) throw new ArgumentException("Value cannot be null or empty.", userName);
if (String.IsNullOrEmpty(password)) throw new ArgumentException("Value cannot be null or empty.", password);
if (String.IsNullOrEmpty(email)) throw new ArgumentException("Value cannot be null or empty.", email);
MembershipCreateStatus status;
provider.CreateUser(userName, password, email, null, null, true, null, out status);
return status;
}
}
The only examples I've found so far requires a "MockMembershipProvider" with a local database setup... seems quite odd to me.
I want to test that when my form data is posted back to my controllers that the data annotations and the model binding is going to do its job and give the correct model state. After googling for a while I can't find a really good tutorial or article that shows how to do this.
Can anyone point me in the right direction? What is the best practice in this area? I have read that I may need to use moq and MVCContrib but I have not read a tutorial that makes me shout, "Yes, this is the right way to do it!"
I am doing Automated coded ui testing in asp.net 2010 for web application. I am testing site and i need to know how can i create the test which will work with all browsers.

I want to mock ASP.NET 3.5 behavior in order to unit test my WebControls: I want to test how they perform with mock data with existing system of events. Basically I want to test generated result HTML based on input mock data. How to do it? I looked into NMock, but it doesn't suit my needs for 2 reasons:
It just runs ASP.NET server in separate process in order to get resulting HTML; My WebControls output HTML as a text on render, so there are elements which do not correspond to any ASP.NET control (except LiteralControl in some cases). Also, I have huge legacy system, so rewriting everything for MVC won't work for me (too much job), I need to write unit tests to existing controls.
I just started my first MVC 2 project in VS 2010. I decided to start the debugger, just to see the default controllers in action, and have received several of the following kinds of errors for the test unit project:
Error 1 The type or namespace name 'Controllers' does not exist in the namespace 'MajorProductions' (are you missing an assembly reference?) c:userskevindocumentsvisual studio 2010ProjectsMajorProductionsMajorProductions.TestsControllersHomeControllerTest.cs
8 24 MajorProductions.Tests
From what I can see, however, MajorProductions.Controllers does exist, as it's created by default in my regular/non-test project.The unit test code in question is:
[Code]....
And the error is being triggered by the using MajorProductions.Controllers line. I have similar errors elsewhere in my unit test project, so I figure if I can fix this, I can fix the others.
Is it possible to write unit tests against razor view in MVC 3? If yes, can anyone point me to code sample to unit test a razor view in MVC 3?
View 2 RepliesWe wanted to upgrade our projects from ASP.NET MVC 2 to 3. Most of our tests succeeded, but there are some that fail on ValueProviderFactories.Factories.GetValueProvider(context).
Here is a simple test class that ilustrates the problem.
[TestFixture]
public class FailingTest
{
[Test]
public void Test()
{
var type = typeof(string);
// any controller
AuthenticationController c = new AuthenticationController();
var httpContext = new Mock<HttpContextBase>();
var context = c.ControllerContext = new ControllerContext(httpContext.Object, new RouteData(), c);

I created a little web service to minify JavaScript, and everything was nice, with all my tests passing. Then I noticed a bug: if I tried to minify alert('<script>');, it would throw a HttpRequestValidationException.
So that's easy enough to fix. I'll just add [AllowHtml] to my controller. But what would be a good way to unit test that this doesn't happen in the future?
The following was my first thought:
[TestMethod]
public void Minify_DoesntChokeOnHtml()
{
try
{
using (var controller = ServiceLocator.Current.GetInstance<MinifyController>())
{
return controller.Minify("alert('<script></script>');");
}
}
catch (HttpRequestValidationException)
{
Assert.Fail("Request validation prevented HTML from existing inside the JavaScript.");
}
}
However, this doesn't work since I am just getting a controller instance and running methods on it, instead of firing up the whole ASP.NET pipeline.
What would be a good unit test for this? Maybe reflector on the controller method to see if the [AllowHtml] attribute is present? That seems very structural, and unlikely to survive a refactoring; something functional might make more sense.
I have been spinning my wheels now for awhile trying to figure out how I can possibly unit test the following code. At first I was going to use Moq to mock everything, but it doesn't include the ability to mock sealed classes. I know I need to abstract out the calls to the implementation (Configuration) using an interface? but I can't seem to make it all work right. The code can be altered but I would prefer to keep the methods static, unless you can present a compelling reason not to. You can add interfaces or create whatever seams are needed. Also, GetConnStringByName() can be refactored to return the relevant string instead of a ConnectionStringSettings. Thoughts?

Since I upgraded from MVC 2 to MVC 3 RC, using TryUpdateModel causes a NullReferenceException. This problem only occurs when running my action method as part of a unit test. Running it on the actual server works as expected. Here's a stack trace of the exception:

My guess is that this has to do with the new way DI works in MVC3, but I can't figure out what I'm doing wrong. Perhaps there is something in terms of DI setup that is required in MVC 3, but wasn't required in MVC 2?
A friend suggested instead of having a backend class which verifies the user permission in every public function (results are cached and non static) i should have a more 'streamlined' site. When i dropped the backend i also drop the database code and merged them in the appropriate user permission (base user, logged_in_user, moderator).
The site code looks better now that merging them has decreased LOC (tons of LOC in fact) and i write Method() instead of backend.Method() which increases readability. However now that i have no backend how am i suppose to unit test my code? and what about things like user file upload with different extensions? (txt vs jpg vs FLAC)
