[tor-commits] [tor/master] test: Move duplicate HS test code and unify it
commit 0cc18ef64cc184d3af0b87378be10f2a8a163fc6
Author: David Goulet <dgoulet@xxxxxxxxxxxxxx>
Date: Fri Apr 7 10:28:57 2017 -0400
test: Move duplicate HS test code and unify it
Create the hs_test_helpers.{c|h} files that contains helper functions to
create introduction point, descriptor and compare descriptor.
Used by both the hs cache and hs descriptor tests. Unify them to avoid code
duplication.
Also, this commit fixes the usage of the signing key that was wrongly used
when creating a cross signed certificate.
