## Testing Best Practices

1. **Isolation**: Each test is independent and doesn't affect others
2. **Clarity**: Test names clearly describe what is being tested
3. **Coverage**: Both success and failure paths are tested
4. **Edge Cases**: Null, empty, and boundary conditions are covered
5. **Resources**: Test resources are properly managed and cleaned up

When adding new tests:

        // Then
        assertEquals(expiration, result);
        verify(mockReferralData).getExpiration();
    }

    @Test
    @DisplayName("Should get next referral")
    void testNext() {
        // Given
        DfsReferralData nextReferral = mock(DfsReferralData.class);
        when(mockReferralData.next()).thenReturn(nextReferral);

        // When

        byte[] testKey = new byte[16];
        new SecureRandom().nextBytes(testKey);

        // When - Create context with SecureKeyManager using same key for both operations
        Smb2EncryptionContext context = new Smb2EncryptionContext(EncryptionNegotiateContext.CIPHER_AES128_GCM, DialectVersion.SMB311,
                testKey, testKey, keyManager);
