### RequiresThreadAttribute (NUnit 2.5)

The RequiresThreadAttribute is used to indicate that a test method, class or assembly should be run on a separate thread. Optionally, the desired apartment for the thread may be specified in the constructor.

Note: This attribute, used with or without an ApartmentState argument will always result in creation of a new thread. To create a thread only if the current ApartmentState is not appropriate, use RequiresSTAAttribute or RequiresMTAAttribute.

#### Examples

    // A thread will be created and used to run
    // all the tests in the assembly
    [assembly:RequiresThread]

    ...

    // TestFixture requiring a separate thread
    [TestFixture, RequiresThread]
    public class FixtureOnThread
    {
      // A separate thread will be created and all
      // tests in the fixture will run on it.
    }

    [TestFixture]
    public class AnotherFixture
    {
      [Test, RequiresThread]
      public void TestRequiringThread()
      {
        // A separate thread will be created for this test
      }

      [Test, RequiresThread(ApartmentState.STA)]
      public void TestRequiringSTAThread()
      {
        // A separate STA thread will be created for tnis test.
      }
    }
