### Question:
ISOField extends ISOComponent implements Cloneable, Externalizable { @Override public Object getValue() { return value; } ISOField();  ISOField(int n);  ISOField(int n, String v); @Override byte[] pack(); @Override int unpack(byte[] b); @Override void unpack(InputStream in); @Override Object getKey(); @Override Object getValue(); @Override void setValue(Object obj); @Override byte[] getBytes(); @Override void dump(PrintStream p, String indent); @Override void setFieldNumber(int fieldNumber); @Override int getFieldNumber(); @Override void writeExternal(ObjectOutput out); @Override void readExternal(ObjectInput in);  }### Answer:
@Test public void testGetValue() throws Throwable { String result = (String) new ISOField(100, "testISOFieldv").getValue(); assertEquals("testISOFieldv", result, "result"); }
@Test public void testGetValue1() throws Throwable { Object result = new ISOField(100).getValue(); assertNull(result, "result"); }
