From 94ff1c62dca4adf1912e5cf25fae73f1024bcc06 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Manuel=20P=C3=A9gouri=C3=A9-Gonnard?= Date: Tue, 27 Jun 2017 12:51:52 +0200 Subject: [PATCH] Add tests for flags passed to f_vrfy The tests cover chains of length 0, 1 and 2, with one error, located at any of the available levels in the chain. This exercises all three call sites of f_vrfy (two in verify_top, one in verify_child). Chains of greater length would not cover any new code path or behaviour that I can see. --- tests/data_files/Makefile | 18 ++++++++++ tests/data_files/server5-ss-expired.crt | 12 +++++++
