I added a simple *unit* test under "test/lib."
As I said before, however, no existing configuration enables either
   CONFIG_X509_CERTIFICATE_PARSER, nor
   CONFIG_PKCS7_MESSAGE_PARSER

and the related code won't be built or exercised in any way.
So I made a small trick to Kconfig:

=== 8< ===
config UT_LIB
        bool "Unit tests for library functions"
        depends on UNIT_TEST
        default y
        help
          Enables the 'ut lib' command which tests library functions like
          memcat(), memcyp(), memmove().

if UT_LIB

config UT_LIB_ASN1
        bool "Unit test for asn1 compiler and decoder function"
        default y
        imply ASYMMETRIC_KEY_TYPE
        imply ASYMMETRIC_PUBLIC_KEY_SUBTYPE
        imply X509_CERTIFICATE_PARSER
        imply PKCS7_MESSAGE_PARSER
        imply RSA_PUBLIC_KEY_PARSER
        help
          Enables a test which exercises asn1 compiler and decoder function
          via various parsers.

endif
=== >8 ===

So as long as UT_LIB is enabled and run by one of Travis CI test cases,
a new test for ASN1 will also be exercised.
(I don't know which one will invoke "ut" command.)

Do you agree to this approach?

Thanks,
