### Question:
CloseSessionRespPars extends AbstractApduResponseParser { public byte[] getSignatureLo() { return signatureLo; } CloseSessionRespPars(ApduResponse response); byte[] getSignatureLo(); byte[] getPostponedData();  }### Answer:
@Test public void TestToPOHalfSessionSignature() { byte[] apduResponse = new byte[] {(byte) 0x4D, (byte) 0xBD, (byte) 0xC9, 0x60, (byte) 0x90, 0x00}; byte[] apduResponseCaseTwo = new byte[] {(byte) 0xA8, 0x31, (byte) 0xC3, 0x3E, (byte) 0xA7, 0x21, (byte) 0xC2, 0x2E, (byte) 0x90, 0x00}; byte[] apduResponseCaseThree = new byte[] {(byte) 0xA8, 0x31, (byte) 0xC3, (byte) 0x90, 0x00}; byte[] sessionSignature = new byte[] {(byte) 0x4D, (byte) 0xBD, (byte) 0xC9, 0x60}; byte[] sessionSignatureCaseTwo = new byte[] {(byte) 0xA7, 0x21, (byte) 0xC2, 0x2E}; { CloseSessionRespPars pars = new CloseSessionRespPars(new ApduResponse(apduResponse, null)); Assert.assertArrayEquals(sessionSignature, pars.getSignatureLo()); } { CloseSessionRespPars pars = new CloseSessionRespPars(new ApduResponse(apduResponseCaseTwo, null)); Assert.assertArrayEquals(sessionSignatureCaseTwo, pars.getSignatureLo()); } { try { CloseSessionRespPars pars = new CloseSessionRespPars(new ApduResponse(apduResponseCaseThree, null)); Assert.fail(); } catch (IllegalArgumentException ex) { } } }
