For this example NUnit version 2.5 or greater is required.
Consider the following enum and test object.
public enum AnimalEnum : byte
{
None,
Dog,
Cat
}
public class ObjectToTest
{
public object...
Exploiting NUnit attributes (ValueSourceAttribute)
Often times it become necessary to use reflection in a unit test to verify that all child classes pass a particular test.
There are three basic ways to handle this:
Don’t write the test, code with no tests is always bug-free right?
Create an array of all of the child types. This is easy to do but not very scalable if the object is likely to be extended many times.
Use reflection to find...

FirstValue = 0,
SecondValue = 1
}
private SomeEnum _value;
public void ToggleValue()
{
