/* BACKGROUND:
*
* This unit test could be used for testing rrset-dump with newly implemented RR types.
* But so far, the functional test records/load is used for this purpose.
* This unit test ought to catch different quirks of knot_rrset_txt_dump,
* like re-allocating the given output buffer based on errcode (KNOT_ESPACE).
