• Every class has a tester class; for example, MyClass would have MyClassTests
• In MyClassTests, multiple test methods would be setup to test each of the methods in MyClass
• Test names would be in this format: MethodName_Scenario_ReturnValue

Tests for large classes would get out of control! There could be several test methods for a single method on the original class. Imagine a tester class if the original class had 20 methods.

However, thanks to this excellent tip from Phil Haack, this situation can be cleaned up and put into an easier to manage form.

By structuring your unit test classes to contain nested classes, each designated to test a single function, you can have a set of tests look like this:

For a further explanation, I would highly recommend reading Phil’s post: Structuring Unit Tests. I’m going to be trying this out with my testing environment (I use nunit) over the next few weeks.

using System.Text.RegularExpressions;

namespace CustomStringMethods
{
	public static class PhoneNumber
	{
		#region Class Methods

		public static string StripAllButDigits(this string s)
		{
			return (s == null) ? string.Empty : Regex.Replace(s, @"\D", string.Empty);
		}

		#endregion
	}
}

Obviously this can be used for more than just phone numbers.
