### Testing

The project uses JUnit 4 with embedded OpenSearch for integration testing:

            // Act

            assertEquals(3, n, "Should report bytes read from SMB2 response");

            // Verify the request offset equals the skip value (2)
            ArgumentCaptor<Smb2ReadRequest> cap = ArgumentCaptor.forClass(Smb2ReadRequest.class);
