We also drive as much of the route table collector as is possible without a real rtg process running somewhere. Send and receive functions are indirectly exercised from the rmr_nng_static_test module as it tests the user facing send/receive/call/rts functions. These tests should exercise specific cases for the internal functions as they will not specifically be driven elsewhere. This requires the gen_rt funcition that is in the test_gen_rt module and should have been included by the test module(s) which include this. */ static int sr_nng_test() { uta_ctx_t* ctx; // context needed to test load static rt uta_ctx_t* real_ctx;
