### Question:
FilterWhereBuilder { public StringBuilder getWhere() { return where; }  void join(final String operator, final FilterWhereBuilder l, final FilterWhereBuilder r); List<SQLParam> getParams(); StringBuilder getWhere(); void addBind(final SQLParam param, final String operator); void addNull(final String name); boolean isIn(); String getWhereClause();  }### Answer:
@Test public void testGetWhere() { FilterWhereBuilder actual = new FilterWhereBuilder(); assertNotNull(actual); final SQLParam param = new SQLParam(NAME, VALUE); actual.addBind(param, OPERATOR); assertNotNull(actual.getWhere()); assertEquals("name = ?", actual.getWhere().toString()); }
@Test public void testEmptyWhere() { FilterWhereBuilder actual = new FilterWhereBuilder(); assertNotNull(actual); assertNotNull(actual.getWhere()); assertEquals("", actual.getWhere().toString()); }
