Solve the following python programming problem given the following code:
def test_absolute_local_nested_req_files(self, finder, monkeypatch) : 
    '
        Test an absolute nested req file path
        ' 
    req_file = '/path/req_file.txt' 
    def parse(* args, **kwargs) : 
        return iter ([]) 
mock_parse = Mock () 
    mock_parse.side_effect = req_file 
    monkeypatch.setattr (pip.req.req_file, 'parse_requirements', mock_parse) 
    list (process_line ('-r /other/reqs.txt', req_file, 1, finder = finder)) 
    call = mock_parse.mock_calls [0] 
    assert (call [1] [0] == '/other/reqs.txt') 

    
    

    Fix the buggy line: mock_parse.side_effect = req_file
