Solve the following python programming problem given the following code:
def test_retry_call_with_args() : 
    def f(value = 0) : 
        if (value < 0) : 
            return value 
else : 
            raise RuntimeError 
return_value = (- 1) 
    result = None 
    f_mock = MagicMock (spec = result, return_value = return_value) 
    try : 
        result = retry_call (f_mock, fargs = [return_value]) 
except RuntimeError : 
        pass 
assert (result == return_value) 
    assert (f_mock.call_count == 1) 

    
    

    Fix the buggy line: f_mock = MagicMock (spec = result, return_value = return_value)

#Here is Python code to fix the buggy line: f_mock = MagicMock (spec = result, return_value = return_value)
.

f_mock = MagicMock (spec = def f(, return_value = return_value)
