### Question:
ActionWorkItemSetFieldCol52 extends ActionSetFieldCol52 { public void setWorkItemName( String workItemName ) { this.workItemName = workItemName; }  @Override List<BaseColumnFieldDiff> diff( BaseColumn otherColumn ); String getWorkItemName(); void setWorkItemName( String workItemName ); String getWorkItemResultParameterName(); void setWorkItemResultParameterName( String workItemResultParameterName ); String getParameterClassName(); void setParameterClassName( String parameterClassName ); @Override boolean equals(Object o); @Override int hashCode(); static final String FIELD_WORK_ITEM_NAME; static final String FIELD_WORK_ITEM_RESULT_PARAM_NAME; static final String FIELD_PARAMETER_CLASSNAME; }### Answer:
@Test public void testDiffWorkItemName() { column1.setWorkItemName("WID1"); column2.setWorkItemName("WID2"); checkSingleDiff(FIELD_WORK_ITEM_NAME, "WID1", "WID2", column1, column2); assertNotEquals(column1, column2); }
