### Question:
ISOFieldPackager { public void setDescription(String description) { this.description = description; } ISOFieldPackager();  ISOFieldPackager(int len, String description); String getDescription(); void setDescription(String description); int getLength(); void setLength(int len); void setPad(boolean pad); void setTrim(boolean trim); abstract int getMaxPackedLength(); ISOComponent createComponent(int fieldNumber); abstract byte[] pack(ISOComponent c); abstract int unpack(ISOComponent c, byte[] b, int offset); void unpack(ISOComponent c, InputStream in); void pack(ISOComponent c, ObjectOutput out);  }### Answer:
@Test public void testSetDescription() throws Throwable { ISOFieldPackager iFA_LCHAR = new IFA_LCHAR(); iFA_LCHAR.setDescription("testISOFieldPackagerDescription"); assertEquals("testISOFieldPackagerDescription", iFA_LCHAR.getDescription(), "(IFA_LCHAR) iFA_LCHAR.getDescription()"); }
