• Include a detailed description of the bug or suggestion

After running my parameterized tests with -vvv there was a sequence of mixed ?1;2c and ^[[ characters in terminal promt and test output. It looks like in the screen snippet (output from given example code):

The reason is explained here and it occurs because character \x05 is interpreted in special way by terminal when running e.g. cat.

Also notice that \x05 character is missing but \xff is printed correctly.

I'm aware that may not be pytest issue but I don't know exacly which upstream should know about it. If you have any suggestions please tell me and I will report them there.

• Minimal example if possible
  Test file which generates this output.

import pytest
import struct

@pytest.mark.parametrize('val, ex_bytes', [
    pytest.param(1, b'\x01', id="This doesn't test for \x05 presence."),
    (5, b'\x05'),
    (255, b'\xff'),
])
def test_b(val, ex_bytes):
    assert struct.pack('B', val) == ex_bytes
