/**
 * @class   vtkTestDataArray
 * @brief   An implementation of vtkGenericDataArray for testing
 * fallback algorithms.
 *
 *
 * vtkTestDataArray is derived from vtkGenericDataArray, and is deliberately
 * omitted from VTK's whitelist of dispatchable data arrays. It is used to test
 * the fallback mechanisms of algorithms in the case that array dispatch fails.
