private void testPairAgainstMapType(DataType dataTypeArg0, DataType dataTypeArg1, MapType<?, ?> mapType) {
    // Special case: DataType varchar yields Codec.rawTypeToDataType(...) => text causing assertion fail
    // Solution: Remove DataType.varchar and check that it yields DataType.text

    // In the map case this would be quite many combinations of text/varchar so I translate varchar to text
    // in order to expect text instead of varchar back from those cases:
    if (dataTypeArg0.equals(varchar()))
        dataTypeArg0 = text();//from  ww  w.ja v a  2  s. co  m
    if (dataTypeArg1.equals(varchar()))

    Assert.assertEquals(Codec.rawTypeToDataType(mapType.nameComparator()), dataTypeArg0);
    Assert.assertEquals(Codec.rawTypeToDataType(mapType.valueComparator()), dataTypeArg1);
