        state1.joined = true;
        ck_assert_msg(err == TOX_ERR_CONFERENCE_NEW_OK, "failed to create a conference: err = %d", err);
        fprintf(stderr, "Created conference: id = %u\n", state1.conference);

This is a printf so go ahead and add a period.

I'd rather not in this PR. That would make it inconsistent with every other printf in this file. Feel free to make a PR to consistently change that in this file.
