### Question:
VISA1Packager extends SimpleLogSource implements ISOPackager, VISA1ResponseFilter { public ISOMsg createISOMsg() { return new ISOMsg(); } VISA1Packager(int[] sequence, int respField, String badResultCode, String okPattern); void setVISA1ResponseFilter(VISA1ResponseFilter filter); @Override byte[] pack(ISOComponent c); String guessAutNumber(String s); @Override int unpack(ISOComponent m, byte[] b); void unpack(ISOComponent m, InputStream in); String getFieldDescription(ISOComponent m, int fldNumber); String getDescription(); ISOMsg createISOMsg(); static final byte[] FS; }### Answer:
@Test public void testCreateISOMsg() throws Throwable { int[] sequence = new int[0]; ISOMsg result = new VISA1Packager(sequence, 100, "testVISA1PackagerBadResultCode", "testVISA1PackagerOkPattern") .createISOMsg(); assertEquals(0, result.getDirection(), "result.getDirection()"); }
