commit 92af8e511394685f7a39224ec1f73ce79fcf2c42 Author: Nick Mathewson <nickm@torproject.org> Date: Mon Dec 3 13:22:23 2018 -0500 Add a framework for testing set_routerstatus_from_routerinfo(). Additionally, use it to test that is_staledesc is set correctly. Eventually we'll want to test all the other flags, but I'm aiming for only adding coverage on the changed code here. --- src/test/include.am | 1 + src/test/test.c | 3 +- src/test/test.h | 1 + src/test/test_voting_flags.c | 192 +++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 196 insertions(+), 1 deletion(-) diff --git a/src/test/include.am b/src/test/include.am index e5eae56e2..d0f71fa66 100644 --- a/src/test/include.am +++ b/src/test/include.am @@ -177,6 +177,7 @@ src_test_test_SOURCES += \ src/test/test_util.c \ src/test/test_util_format.c \ src/test/test_util_process.c \ + src/test/test_voting_flags.c \ src/test/test_voting_schedule.c \ src/test/test_x509.c \ src/test/test_helpers.c \ diff --git a/src/test/test.c b/src/test/test.c index 17b736d30..bbb00da78 100644 --- a/src/test/test.c +++ b/src/test/test.c @@ -866,7 +866,8 @@ struct testgroup_t testgroups[] = { { "crypto/pem/", pem_tests }, { "dir/", dir_tests }, { "dir/md/", microdesc_tests }, - { "dir/voting-schedule/", voting_schedule_tests }, + { "dir/voting/flags/", voting_flags_tests }, + { "dir/voting/schedule/", voting_schedule_tests }, { "dir_handle_get/", dir_handle_get_tests }, { "dns/", dns_tests }, { "dos/", dos_tests }, diff --git a/src/test/test.h b/src/test/test.h index 092356f0f..1d8f79717 100644 --- a/src/test/test.h +++ b/src/test/test.h @@ -265,6 +265,7 @@ extern struct testcase_t tortls_tests[];
