TestFixtureAttribute (NUnit 2.0)

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.

Example:

namespace NUnit.Tests
{
  using System;
  using NUnit.Framework;

  [TestFixture]
  public class SuccessTests
  {
    // ...
  }
}
