### Question:
BASE1Header extends BaseHeader { public String getSource() { return ISOUtil.bcd2str (this.header, 8, 6, false); } BASE1Header();  BASE1Header(String source, String destination);  BASE1Header(String source, String destination, int format);  BASE1Header(byte[] header); int getHLen(); void setHFormat(int hformat); int getFormat(); void setRtCtl(int i); void setFlags(int i); void setStatus(int i); void setBatchNumber(int i); void setFormat(int format); void setLen(int len); void setDestination(String dest); void setSource(String src); String getSource(); String getDestination(); void swapDirection(); boolean isRejected(); String getRejectCode(); String formatHeader(); static final int LENGTH; }### Answer:
@Test public void testGetSource() throws Throwable { String result = new BASE1Header().getSource(); assertEquals("000000", result, "result"); }
@Test public void testGetSourceThrowsArrayIndexOutOfBoundsException() throws Throwable { BASE1Header bASE1Header = new BASE1Header(); byte[] header = new byte[3]; bASE1Header.unpack(header); try { bASE1Header.getSource(); fail("Expected ArrayIndexOutOfBoundsException to be thrown"); } catch (ArrayIndexOutOfBoundsException ex) { } }
