+Test generated by RoostGPT for test unit-java-adk using AI Type Azure Open AI and AI Model gpt-5

+ROOST_METHOD_HASH=content_f95ec3ddc9
+ROOST_METHOD_SIG_HASH=content_accc65ce1a
+
+
+Scenario 1: Returns the same Content instance that was supplied at construction
+
+Details:
+  TestName: returnsSameContentInstance
+  Description: Verify that the content() method returns the exact Content object that was used to build the AutoValue_MemoryEntry instance (reference identity, not a copy).
+
+Execution:
+  Arrange: Create a valid Content instance (e.g., a concrete instance or a simple test double) and build a MemoryEntry via the Builder with that Content.
+  Act: Call content() on the built MemoryEntry.
+  Assert: Use JUnit assertions to confirm that the returned Content is the same object instance as the one provided during construction (reference equality).
+
+Validation:
+  This assertion verifies that content() is a simple accessor returning the internal field without copying or transforming it. It ensures the method exposes the exact Content reference stored in the entry, which is important for consumers relying on object identity or avoiding unnecessary allocations.
