Review Comment:
Looks like this isn't correct. An `InternalRow` will represent the value as
`VariantVal` so this is the correct validation:
```java
case VARIANT:
assertThat(expected).as("Should expect a
Variant").isInstanceOf(Variant.class);
assertThat(actual).as("Should be a
Variant").isInstanceOf(VariantVal.class);
VariantVal actualVariant = (VariantVal) actual;
VariantMetadata actualMetadata =
VariantMetadata.from(
ByteBuffer.wrap(actualVariant.getMetadata()).order(ByteOrder.LITTLE_ENDIAN));
VariantValue actualValue =
VariantValue.from(
actualMetadata,
ByteBuffer.wrap(actualVariant.getValue()).order(ByteOrder.LITTLE_ENDIAN));
VariantTestUtil.assertEqual(((Variant) expected).metadata(),
actualMetadata);
VariantTestUtil.assertEqual(((Variant) expected).value(),
actualValue);
break;
```
