I copied the tests from TestMapLookupExtraction
but testing retainMissingValue, injective etc again is not really necessary
since they're actually a function of LookupExtraction.
I left it anyway because it's only 2 lookup extraction functions and not too messy.
If more get added I would extract the tests of injective etc to a separate class.
