test_client_auth_pkcs11_connection should work under TLS 1.2
test_client_auth_pkcs11_connection fails when run under TLS 1.2:
MockPKCS11:ERROR:../../../../Projects/glib-networking/tls/tests/mock-pkcs11.c:1997:C_SignInit: code should not be reached
Problem is the mock module is trying to use RSA-PSS, which isn't available in TLS 1.2.
To test, run with the environment variable G_TLS_GNUTLS_PRIORITY='NORMAL:%COMPAT:!VERS-TLS1.3'
