Seems I missed that in conversion; but it should be migrated to phpunit, not removed. Main point is the cache:configure options.

Also, this should be done on 10.0/bugfixes branch I guess.

It corresponds to @tags cache occurrences in thd PHP Units tests. The command should indeed be fixed to run them with each available test adapter.
