/**
 * Test Description
 * ------------------------
 *    - Verify that data is correctly copied from a symbol. A graph is constructed to which a
 * MemcpyFromSymbol node is added. After graph execution, values in destination memory are compared
 * against values known to be in symbol memory.
 * The test is run for scalar, const scalar, array, and const array symbols of types char, int,
 * float and double. For array symbols, the test is repeated for zero and non-zero offset values.
 * Verification is performed for destination memory allocated on host and device.
 * Test source
 * ------------------------
 *    - unit/graph/hipGraphAddMemcpyNodeFromSymbol.cc
 * Test requirements
 * ------------------------
 *    - HIP_VERSION >= 5.2
