Solve the following python programming problem given the following code:
@ pytest.mark.parametrize ('type', ['Error', 'Failure']) 
def test_testcase_adderrorandfailure_defers(testdir, type) : 
    testdir.makepyfile (('
        from unittest import TestCase
        import pytest
        class MyTestCase(TestCase):
            def run(self, result):
                excinfo = pytest.raises(ZeroDivisionError, lambda: 0/0)
                try:
                    result.add%s(self, excinfo._excinfo)
                except KeyboardInterrupt:
                    raise
                except:
                    pytest.fail("add%s should not raise")
            def test_hello(self):
                pass
    ' % (type, testdir))) 
    result = testdir.runpytest () 
    assert ('should not raise' not in result.stdout.str ()) 

    
    

    Fix the buggy line: testdir.makepyfile (('
        from unittest import TestCase
        import pytest
        class MyTestCase(TestCase):
            def run(self, result):
                excinfo = pytest.raises(ZeroDivisionError, lambda: 0/0)
                try:
                    result.add%s(self, excinfo._excinfo)
                except KeyboardInterrupt:
                    raise
                except:
                    pytest.fail("add%s should not raise")
            def test_hello(self):
                pass
    ' % (type, testdir)))
