Sorry that was the wrong function name. It should be:
test_to_string_specified_header
df = DataFrame({'x': [1, 2, 3], 'y': [4, 5, 6]})

df_s = df.to_string(header=['X', 'Y'])
expected = ' X Y\n0 1 4\n1 2 5\n2 3 6'

self.assertEqual(df_s, expected)

with tm.assertRaises(ValueError):
df.to_string(header=['X'])

def test_to_string_no_index(self):
df = DataFrame({'x': [1, 2, 3], 'y': [4, 5, 6]})
