# The list of operator tests
# Each dictionary entry for an op is a dictionary with the following required members:
#   'operands': tuple (number_of_placeholder_tensors, number_of_constant_tensors)
#   'build_fcn: tuple (Test builder function, Tensor generator function,
#                      Argument generator function)
#   'types': list of Tensorflow types that should be tested for this op
#               OR
#            a dictionary of {'framework_name': [type_list] } for cases where only
#            a subset of the types should be tested in each framework.  This can also
#            be used to restrict an operator to a particular framework.
#
# And optional members:
#   'template': boolean (indicates that this is a templated op which gets further
#               processing in createDynamicOpLists)
#   'bias':     boolean indicating that there is a bias component to be generated
#   'qtypes':   List of QuantType quantized types to generate for this op
#   'rank':     tuple (lowest rank, highest rank). Dimension range of input tensor.
