I found this test fixture hilarious.

[TestFixture]
public class ValidateNamingConventions
{
    private System.Type[] types;

    [SetUp]
    public void Setup()
    {
        types = typeof(ISearchFactory).Assembly.GetExportedTypes();            
    }

    [Test]
    public void InterfacesStartsWithI()
    {
        foreach (System.Type type in types)
        {
            if(type.IsInterface==false)
                continue;
            Assert.IsTrue(type.Name.StartsWith("I"),type.Name);
        }
    }

    [Test]
    public void FirstLaterOfMethodIsCapitalized()
    {
        foreach (System.Type type in types)
        {
            foreach (MethodInfo method in type.GetMethods())
            {
                Assert.IsTrue(char.IsUpper(method.Name[0]), type.FullName + "." + method.Name);
            }
        } 
    }

    [Test]
    public void AttributesEndWithAttribute()
    {
        foreach (System.Type type in types)
        {
            if (type.IsAssignableFrom(typeof(Attribute)))
                continue;
            Assert.IsTrue(type.Name.EndsWith("Attribute"), type.Name);
     
        }
    }
}
