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.

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.

Example:

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

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

Imports System
Imports Nunit.Framework

Namespace Nunit.Tests

  <TestFixture()> Public Class SuccessTests
    ' ...
  End Class
End Namespace

#using <Nunit.Framework.dll>
using namespace System;
using namespace NUnit::Framework;

namespace NUnitTests
{
  [TestFixture]
  public __gc class SuccessTests
  {
    // ...
  };
}

#include "cppsample.h"

namespace NUnitTests {
  // ...
}

package NUnit.Tests;

import System.*;
import NUnit.Framework.TestFixture;


/** @attribute NUnit.Framework.TestFixture() */
public class SuccessTests
{
  // ...
}
