@sngrl Would you mind to add a test coverage? Literally, it's just about extending already existing data provider in unit tests

@vladvildanov tests already are presented, my PR just makes this commands to use prefixes

\Predis\Command\Redis\ZPOPMIN_Test
\Predis\Command\Redis\ZPOPMAX_Test

@sngrl2 Ah, my bad! Approved

But you also need to run composer style:fix command to fix codestyle issues
