Yes... NUnit currently generates all tests at the time the assembly is loaded,
which is of course before any of them are run. I sometimes call these "static"
tests - although I'm not sure that's the best name.

We also expect to have "dynamic" tests in NUnit 3.0, generated immediately
before the tests are executed. Some existing attributes will be redefined to
produce tests dynamically and new attributes will be added.

This is actually a much more extensive change than you might imagine,
which is why it isn't happening in 2.x.

Status in NUnit V2 Test Framework: Triaged

Bug description:
What happens:

Created a class X that is returned as an IEnumerable<X> in method M of class Z.  
This is used in [TestCaseSource(typeof(Z), "M"]

Class X has been given

		public string TestName { get; private set; }

		public IList<string> Categories { get; private set; }

		public bool Ignored;

In the constructor for X,  these have been initialised
			this.Categories = new List<string> { "foo" };
			this.TestName = note;
			this.Ignored = true;

The test is executed(contrary to Ignored==true).
There are no categories in the NUinit GUI.
The test is not renamed.

What I expect:
The test is flagged as ignore.
There is a category "foo".
The test is named after the string value in TestName.

NUnit 2.5.7.
