### Question:
Identity { public String getEcdsaCurveName() { return ecdsaCurveName; } Identity(URI identityUri, int index, byte[] challengeHidden, String challengeVisual, String ecdsaCurveName); byte[] getChallengeHidden(); String getChallengeVisual(); String getEcdsaCurveName(); String getHost(); String getPort(); String getPath(); String getProto(); String getUser(); int getIndex();  }### Answer:
@Test public void testConstructors_Valid_Ecdsa() { String challengeVisual = "2015-03-23 17:39:22"; byte[] challengeHidden = Utils.HEX.decode("cd8552569d6e4509266ef137584d1e62c7579b5b8ed69bbafa4b864c6521e7c2"); URI uri = URI.create("https: Identity testObject = new Identity(uri, 0, challengeHidden, challengeVisual, "nist256b1"); assertThat(testObject.getEcdsaCurveName()).isEqualTo("nist256b1"); }
