# Copyright (c) 2016, ARM Limited, All Rights Reserved
#
# Purpose
#
# Executes tests to prove various TLS/SSL options and extensions.
#
# The goal is not to cover every ciphersuite/version, but instead to cover
# specific options (max fragment length, truncated hmac, etc) or procedures
# (session resumption from cache or ticket, renego, etc).
#
# The tests assume a build with default options, with exceptions expressed
# with a dependency.  The tests focus on functionality and do not consider
# performance.

# The purpose of the next two tests is to test the client's behaviour when receiving a server
# certificate with an unsupported elliptic curve. This should usually not happen because
# the client informs the server about the supported curves - it does, though, in the
# corner case of a static ECDH suite, because the server doesn't check the curve on that
# occasion (to be fixed). If that bug's fixed, the test needs to be altered to use a
# different means to have the server ignoring the client's supported curve list.

## Interop tests with OpenSSL might trigger a bug in recent versions (including
## all versions installed on the CI machines), reported here:
## Bug report: https://github.com/openssl/openssl/issues/6902
## They should be re-enabled once a fixed version of OpenSSL is available
## (this should happen in some 1.1.1_ release according to the ticket).
