/*
Testcase Scenarios :
Functional-
1) Instantiate a graph with memcpy node, obtain executable graph and update the
   node params with set exec api call. Make sure they are taking effect.
Negative-
1) Pass hGraphExec as nullptr and check if api returns error.
2) Pass GraphNode as nullptr and check if api returns error.
3) Pass destination ptr is nullptr, api expected to return error code.
4) Pass source ptr is nullptr, api expected to return error code.
5) Pass count as zero, api expected to return error code.
6) Pass same pointer as source ptr and destination ptr, api expected to return error code.
7) Pass overlap memory address as source ptr and destination ptr, api expected to return error code.
7) Pass overlap memory as source ptr and destination ptr where source ptr is ahead of destination ptr, api expected to return error code.
8) Pass overlap memory as source ptr and destination ptr where destination ptr is ahead of source ptr, api expected to return error code.
9) If count is more than allocated size for source and destination ptr, api should return error code.
10) If count is less than allocated size for source and destination ptr, api should return error code.
11) Change the hipMemcpyKind from H2D to D2H but allocate pointer memory for H2D, api should return error code.
