如何在运行pytest时让PyCharm显示进度条？

Question

I use pytest and have a test that takes a very long time. So I added a progress bar with progressbar2 .

import progressbar
from time import sleep


def test_progressbar_bug():
    with progressbar.ProgressBar() as bar:
        for i in bar(range(10)):
            sleep(1)

Running this in a terminal with pytest -s gives me a nice test output with a progress bar that updates as time passes.

However, if I try to run this from within PyCharm with a pytest configuration (and -s as option) I just get an empty output. Only after the test is finished the complete progress bar appears.

I also tried to create my own progress display with sys.stdout without any success in PyCharm's integrated pytest.

from time import sleep
import sys


def test_progress_bug():
    for i in range(10):
        sys.stdout.write("\rProgress: %3d" % (i * 100 / 10.) + "%")
        sys.stdout.flush()
        sleep(1)

What do I have to do to display a progress bar that shows the progress of a single test when running pytests in PyCharm?

Edit: I don't really like my current workaround - which is running this as a normal python configuration - because I don't get the fancy test overview of PyCharm:

Test.py

import os

if __name__ == "__main__":
    os.system("pytest -s")

I had the same problem. Just install "progressbar2" lib and it will work
