### Question:
ISOField extends ISOComponent implements Cloneable, Externalizable { @Override public void setValue(Object obj) throws ISOException { if (obj instanceof String) value = (String) obj; else value = obj.toString(); } 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 testSetValue() throws Throwable { ISOField iSOField = new ISOField(100); iSOField.setValue(" W"); assertEquals(" W", iSOField.value, "iSOField.value"); }
@Test public void testSetValue1() throws Throwable { ISOField iSOField = new ISOField(100); iSOField.setValue(200); assertThat("isoField setter", "200", equalTo(iSOField.value)); }
