"colorized" ignored when called without shell?d

[buhtz]

Bug description

Not sure if tis is a bug. So I ask first. I can run pylint on my shell with --output-format=colorized and get the expected nice and fancy output. But when doing this in Python code via subprocess.run() there is no color and also no colorcodes in the output string.

Might it be that the colorized option is ignored by pylint because it can not detected a color supporting terminal?

I tried to do shell=True in subprocess.run() but then pylint do not find any files to lint. This is another problem. But of course having shell=True is not recommended.

Configuration

Not a config file but a unitest

    def test030_pylint(self):
        # Pylint base command
        cmd = [
            'pylint',
            '--output-format=colorized`,
            # Storing results in a pickle file is unnecessary
            '--persistent=n',
            # autodetec number of parallel jobs
            '--jobs=0',
            # Disable scoring  ("Your code has been rated at xx/10")
            '--score=n',
            # PEP8 conform line length (see PyLint Issue #3078)
            f'--max-line-length={PEP8_MAX_LINE_LENGTH}',
            # prevent false-positive no-module-member errors
            '--extension-pkg-whitelist=lxml',
            # List of members which are set dynamically and missed by pylint
            # inference system, and so shouldn't trigger E1101 when accessed.

            # Allowlist variable names
            '--good-names=idx,fp,df',
            # Allow fstrings when logging
            '--disable=logging-fstring-interpolation',
        ]
        # Add py files
        cmd.extend(self.collected_py_files[6:7])

        # subprocess.run(cmd, check=True)
        r = subprocess.run(
            cmd,
            check=False,
            universal_newlines=True,
            capture_output=True)

        print(f'!!!!!!!!!!!!!!!! {r.stdout=}')
        print(f'!!!!!!!!!!!!1!! {r.stderr=}')
        print(f'ÖÖÖÖÖÖÖÖÖÖÖÖÖÖ {r.returncode=}')

        self.assertEqual(0, r.returncode)
