## 🏗️ Architecture & Design Patterns

### Core Design Principles

        }

        when(mockConfig.getLmHostsFileName()).thenReturn(lmhostsFile.getAbsolutePath());

        if (!isWindows) {
            // Should handle IOException gracefully and return null
            NbtAddress result = lmhosts.getByName("ANYHOST", mockContext);
            assertNull(result);
        }

        // Cleanup
        lmhostsFile.setReadable(true);
