net/data/verify_signed_data_unittest/rsa-pkcs1-sha256-using-ecdsa-algorithm.pem

   1 This test specified a valid RSA PKCS#1 v.1.5 signature and RSA key (the same as rsa-pkcs1-sha256.pem).
   2
   3 The problem however is the signature algorithm is indicated as being ECDSA.
   4
   5 Signature verification consequently should fail.
