It depends on what you want to test ECDSA for. If it is part of FIPS 140-2
compliance (it usually is with that test) then you might want to look at the
OpenSSL FIPS module 2.0 effort:

http://www.openssl.org/docs/fips/

That specific test is covered by the fips_ecdsavs utility. If you just want an
ECDSA self test then for FIPS 140-2 a pairwise consistency test is acceptable.
If you definitely need to perform a KAT then you will need to set the 'k'
value.
