Testing Webservices with NUnit

Because NUnit is an exe and you sometimes you need to access web.config and objects that are only present in a web context, you will need to do the following:

- Open the command prompt and cd to C:\Program Files\Microsoft Visual Studio 8\VC, or in Visual Studio 2005 Command Prompt, type wsdl url (where url is the WSDL URL). A C# file will be generated with the name of the webservice. You can add some command line arguments to change the file name or the language. Just type wsdl without any arguments to show the help.

- Move the file to your test project and use it. It will call the webservice

Testing Private Methods

Test Driven Development a practice that is becoming very popular due to the quality assurance that it adds. While it is easy to test public methods, How do I test private methods?

There are 2 ways:

1. Using Helper Class discussed on The Code Project
2. Using Microsoft’s build in Testing Tools

Example:

using Microsoft.VisualStudio.TestTools.UnitTesting;
PrivateObject po = new PrivateObject(new TestClass());
po.Invoke(’PrivateMethodName’); /*This will invoke the private method*/
po.GetField(’PrivateFieldName’); /*This will get the value of a private variable*/
