### Question:
FilterWhereBuilder { public String getWhereClause() { return this.getWhere().toString(); }  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 testGetWhereClause() { FilterWhereBuilder actual = new FilterWhereBuilder(); assertNotNull(actual); final SQLParam param = new SQLParam(NAME, VALUE); actual.addBind(param, OPERATOR); assertEquals("name = ?", actual.getWhereClause()); assertEquals("not one value for binding", 1, actual.getParams().size()); }
