### Question:
NfcUtils { public static boolean verifyPin(NfcTranceiver card, byte[] pin) throws IOException, NfcCardException { VerifyPinApdu apdu = new VerifyPinApdu(pin); ResponseApdu resp = tranceive(card, apdu, "VERIFY PIN"); return resp.getSW1() == 0x90; }  static GenerateSignatureResponseApdu generateSignature(NfcTranceiver card, int keyIndex,
                                                                  byte[] dataToSign, byte[] pin); static GetKeyInfoResponseApdu readPublicKeyOrCreateIfNotExists(NfcTranceiver card, int keyIndex); static boolean generateKeyFromSeed(NfcTranceiver card, byte[] seed, byte[] pin); static byte[] initializePinAndReturnPuk(NfcTranceiver card, byte[] pinBytes); static byte[] changePin(NfcTranceiver card, byte[] currentPin, byte[] newPin); static boolean unlockPin(NfcTranceiver card, byte[] puk); static boolean verifyPin(NfcTranceiver card, byte[] pin); static final byte[] AID_INFINEON_BLOCKCHAIN2GO; }### Answer:
@Test public void testVerifyPin() throws IOException, NfcCardException { when(nfcTranceiver.transceive(any())).thenReturn(new byte[]{(byte) 0x90, 0x00}); final boolean responseApdu = NfcUtils.verifyPin(nfcTranceiver, "1234".getBytes(StandardCharsets.UTF_8)); assertTrue(responseApdu); }
