TestFixture in NUint

This is the attribute that marks a class that contains tests and, optionally, setup or teardown methods.

There are a few restrictions on a class that is used as a test fixture.

• It must be a publicly exported type or NUnit will not see it.
• It must have a default constructor or NUnit will not be able to construct it.
• The constructor should not have any side effects, since NUnit may construct the class multiple times in the course of a session.
