Please use the following code for this new unit test. You need to
add the certificate files test_ecc.example.com.crt and
intermediate.crt to net/data/ssl/certificates.

static string PEMCertFileToDER(const string& file_name) {
  base::FilePath certs_dir = GetTestCertsDirectory();
  scoped_refptr<X509Certificate> cert =
      ImportCertFromFile(certs_dir, file_name);
  CHECK_NE(static_cast<X509Certificate*>(NULL), cert);

  string der_bytes;
  CHECK(X509Certificate::GetDEREncoded(cert->os_cert_handle(), &der_bytes));
  return der_bytes;
}

// A known answer test that allows us to test ProofVerifier without a working
// ProofSource.
TEST(Proof, VerifyECDSAKnownAnswerTest) {

I have used the latest code from you for the above test. Hope that is ok.

Done.
