// .NAME vtkTestingObjectFactory - Object overrides used during testing
// .SECTION Description
// Some vtk examples and tests need to perform differently when they
// are run as tests versus when they are run as individual
// programs. Many tests/examples are interactive and eventually call
// vtkRenderWindowInteration::Start() to initialie the
// interaction. But, when run as tests, these programs should
// exit. This factory overrides vtkRenderWindowInteractor so that the
// Start() method just returns.
// To use this factory:
//   #include "vtkTestingObjectFactory.h"
//   vtkTestingObjectFactory* factory = vtkTestingObjectFactory::New();
//   vtkObjectFactory::RegisterFactory(factory);
//
#include "vtkRenderWindowInteractor.h"
#include "vtkTesting.h" // Required for Test Driver

//BTX
#include <string> // STL Header; Required for string
//ETX

// .NAME vtkTestingInteractor - A RenderWindowInteractor for testing
// .SECTION Description
// Provides a Start() method that passes arguments to a test for
// regression testing and returns. This permits programs that
// run as tests to exit gracefully during the test run without needing
// interaction.
