How to test Web Methods with NUnit

[Phillip Donegan]

Hi all, In my solution I already have lots of business object unit tests. However I also want to test the web service layer. So to do this I've added another project to the solution and added a project reference to the web service layer. So now I can see all the web methods. The problem I have is that when I want to go to the database my method GetDAOFactory() always returns null. I think this is because the global file inherits the HttpApplication class. E.G. Try and get the customer or create a new one 1) private Customer GetCustomerInSession() { Customer customer = Session[PropertyCustomer] as Customer; if (customer == null) { Session[PropertyCustomer] = customer = new Customer(GetDAOFactory()); } return customer; } Get the DAO Factory this returns null 2) private IDAOFactory GetDAOFactory() { return Application[Global.DAOFactorySetting] as IDAOFactory; } I think the reason is because global inherits HttpApplication 3) public class Global : HttpApplication { protected void Application_Start(object sender, EventArgs e) { // create data access implementation string connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["DevBox"].ConnectionString; Application[DAOFactorySetting] = new ADODAOFactory(ProviderType.SqlServer, connectionString); } protected void Application_End(object sender, EventArgs e) { } public static readonly string DAOFactorySetting = "DAOFactory"; } Any ideas why its returning null? I've thought of one solution and that would be to change the reference to a web reference. The only problem then is that I would either have to add a localhost web reference which wouldn't work with the CI build. Or to reference the published development app layer, but that would mean that when I change my code I wouldn't be able to test it until it was committed!! Any help would be greatly appreciated. I'm using C#.Net 2.0 with NUnit 2.4.7 Phil P.S. I've copied the connectionString DevBox to the App.config in the WebServiceTests project so that it can see it.
