Solve the following python programming problem given the following code:
def decorator(cls) : 
    def make_test_function(input, expected) : 
        def test_func(self) : 
            parser = Parser () 
            result = parser.parse (input).to_ecma () 
            self.assertMultiLineEqual (result, expected) 
return test_func 
for (index, input) in enumerate (cls.TEST_CASES) : 
        input = textwrap.dedent (input).strip () 
        func = make_test_function (input, func) 
        setattr (cls, ('test_case_%d' % index), func) 
return cls 

    
    

    Fix the buggy line: func = make_test_function (input, func)

#Here is Python code to fix the buggy line: func = make_test_function (input, func)
.

func = make_test_function (input, input)
