/**
Testcase Scenarios :
Functional-
1) Create a graph, add Memcpy node to graph, update the Memcpy node params with set and make sure
they are taking effect. Negative- 1) Pass pGraphNode as nullptr and check if api returns error. 2)
Pass destination ptr is nullptr, api expected to return error code. 3) Pass source ptr is nullptr,
api expected to return error code. 4) Pass count as zero, api expected to return error code. 5) Pass
same pointer as source ptr and destination ptr, api expected to return error code. 6) Pass overlap
memory as source ptr and destination ptr where source ptr is ahead of destination ptr, api expected
to return error code. 7) Pass overlap memory as source ptr and destination ptr where destination ptr
is ahead of source ptr, api expected to return error code. 8) If count is more than allocated size
for source and destination ptr, api should return error code. 9) If count is less than allocated
size for source and destination ptr, api should return error code.
