Solve the following python programming problem given the following code:
@ pytest.mark.skipif ((not hasattr (py.path.local, 'mksymlinkto')), reason = 'symlink not available on this platform') 
def test_tmpdir_always_is_realpath(testdir) : 
    realtemp = testdir.tmpdir.mkdir ('myrealtemp') 
    linktemp = testdir.tmpdir.join ('symlinktemp') 
    linktemp.mksymlinkto (realtemp) 
    p = testdir.makepyfile ('
        def test_1(tmpdir):
            import os
            assert os.path.realpath(str(tmpdir)) == str(tmpdir)
    ') 
    result = testdir.runpytest ('-s', linktemp, ('--basetemp=%s/bt' % linktemp)) 
    assert (not result.ret) 

    
    

    Fix the buggy line: result = testdir.runpytest ('-s', linktemp, ('--basetemp=%s/bt' % linktemp))

#Here is Python code to fix the buggy line: result = testdir.

result = testdir.runpytest ('-s', p, ('--basetemp=%s/bt' % linktemp))
