Add three test cases exercising the S1GW REST interface for MME pool management. The REST TCs are gated on the mp_rest_enable module parameter in the control block.
TC_rest_mme_list: query the MME pool list via REST and verify it matches the three static entries from the 'mme_pool' section in osmo-s1gw.config (mme0/mme1/mme2 with their respective addresses).
TC_rest_mme_add_del: add a new MME entry at runtime via REST, verify it appears in both the list and individual GET responses, then delete it and confirm it is gone.
TC_rest_mme_del_fallback: delete mme0 from the pool at runtime and verify that a connecting eNB is routed directly to mme1, skipping the deleted entry. The pool is restored to its original state afterwards via f_REST_mme_pool_restore().
Also add: * {ts,tr}_MmeItem templates to S1GW_REST_Types.ttcn * f_REST_mme_find(): returns the integer index of a named entry in a MmeList, or -1 if not found; used for both presence and absence checks * f_REST_mme_pool_restore(): deletes all current entries and re-adds mme0/mme1/mme2 in original order to keep pool state predictable across test cases
