print() doesn't work in debug console while debugging pytests

[zljubisic]

Type: Bug

If I set a breakpoint in pytest test, when I am on the breakpoint, if I enter debug console and execute prints, nothing is showed up.
Is that a bug or feature?

I am not sure that this is the same issue because I have this in settings.json, so it is not matter of defaults.

{
    "python.testing.unittestEnabled": false,
    "python.testing.pytestEnabled": true,
    "python.testing.pytestArgs": [
        "--no-cov", "-s"
    ]
}

{
"python.testing.unittestEnabled": false,
"python.testing.pytestEnabled": true,
"python.testing.pytestArgs": [
"--no-cov", "-s"
]
}

Can you type in sys.argv in the Debug Console to check what are the actual args being received in your case? (i.e.: setting that works for me...).

[zljubisic]

For settings.json like:

{
    "python.testing.pytestArgs": [
        "tests",
        "--no-cov",
        "--capture=no"
        // "-s"
    ],
    "python.testing.unittestEnabled": false,
    "python.testing.pytestEnabled": true,
    "testing.defaultGutterClickAction": "debug"
}

I get:

'--capture=no'
10:
'./tests/test_mytest.py::name of test...]'
len():
11

At the moment I can print, but from time to time print(12) just make an empty line. Do you see different vertical spaces? They are when print fails. Usually I don't have anything as output.

The fact that it doesn't write sometimes due to the clipping is already reported at:

microsoft/vscode#162965

(so, this can be closed as a duplicate).

I don't know is it the same issue.
In microsoft/vscode#162965 problem is dataframe related, here the problem is with general print.
I hope that in the future I will be able to use rich print (from rich import print) to print complex object like nested dictionaries in pretty format.

Hello! This is a duplicate of #19322 which just got resolved in this PR by @harupy.

Usually, end user (UAT) should confirm that problem is solved.

@zljubisic, yes this is true - can someone verify?
