+// TestTransformShortCircuit tests the transformation of short-circuit configuration in AlluxioEngine.
+// It verifies the behavior with different tiered storage configurations (emptyDir vs non-emptyDir volumes),
+// ensuring the correct short-circuit policy, enablement status, and property values are set.
+// The test cases cover:
+//   - When emptyDir volume type is present in tiers (short-circuit disabled)
+//   - When emptyDir volume type is absent (short-circuit enabled)
+// Each test validates:
+//   - The resulting ShortCircuitPolicy
+//   - The ShortCircuit struct values
+//   - The Alluxio properties when applicable
