From: Dr. Stephen Henson Date: Wed, 23 Jul 2014 12:18:06 +0000 (+0100) Subject: Add conditional unit testing interface. X-Git-Tag: master-post-reformat~557 X-Git-Url: https://git.openssl.org/?p=openssl.git;a=commitdiff_plain;h=e0fc7961c4fbd27577fb519d9aea2dc788742715 Add conditional unit testing interface. Don't call internal functions directly call them through SSL_test_functions(). This also makes unit testing work on Windows and platforms that don't export internal functions from shared libraries. By default unit testing is not enabled: it requires the compile time option "enable-unit-test".
