17 : * @file exchangedb/test_auditor_denom_sigs.c
18 : * @brief tests for the exchangedb functions whose primary table is
19 : * `auditor_denom_sigs`
20 : * @author Christian Grothoff
21 : *
22 : * Covers #TALER_EXCHANGEDB_insert_auditor_denom_sig(),
23 : * #TALER_EXCHANGEDB_get_auditor_denom_sig() and
24 : * #TALER_EXCHANGEDB_iterate_auditor_denominations().
25 : *
26 : * The table references `auditors` and `denominations`, and the insert
27 : * resolves both by their natural keys inside the statement -- so an unknown
28 : * auditor or denomination has to come back as "nothing inserted". Fixtures
29 : * come from #TALER_EXCHANGEDB_insert_auditor() and TDB_denom(), whose own
30 : * tables are covered by test_auditors.c and test_denominations.c.
