## 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

            testBlock.setUseUnicode(true);
            byte[] buffer = new byte[100];
            String testString = "Test";

            // Test odd Unicode alignment - headerStart affects alignment
            int bytesWritten = testBlock.writeString(testString, buffer, 2);

            // When even alignment (offset 2), Unicode string starts immediately

        return params.containsKey(key);
