From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Daniel Axtens <dja@axtens.net>
Date: Wed, 10 Jun 2020 17:48:42 +1000
Subject: [PATCH] test_asn1: test module for libtasn1
Import tests from libtasn1 that don't use functionality we don't
import. I have put them here rather than in the libtasn1 directory
because:
- They need much more significant changes to run in the grub
context.
- I don't expect they will need to be changed when updating
libtasn1: I expect the old tests will usually continue to pass on
new versions.
This doesn't test the full decoder but that will be exercised in
test suites for coming patch sets.
