Question: When running tests in PyCharm 2022.3.2 (Professional Edition) using pytest (6.2.4) and Python 3.9 I get the following result in the PyCharm console window:  D:\cenv\python.exe "D:/Program Files (x86)/JetBrains/PyCharm 2022.3.2/plugins/python/helpers/pycharm/_jb_pytest_runner.py" --path D:\tests\test_k.py Testing started at 6:49 PM ... Launching pytest with arguments D:\tests\test_k.py --no-header --no-summary -q in D:\tests ============================= test session starts ============================= collecting ... collected 5 items test_k.py::test_init test_k.py::test_1 test_k.py::test_2 test_k.py::test_3 test_k.py::test_4 ======================= 5 passed, 278 warnings in 4.50s ======================= Process finished with exit code 0 PASSED [ 20%]PASSED [ 40%]PASSED [ 60%]PASSED [ 80%]PASSED [100%]  So the actual warnings don't show. Only the number of warnings (278) is shown. I tried:  selecting: Pytest: do not add "--no-header --no-summary -q" in advanced settings  Setting Additional arguments to -Wall in the Run/Debug configurations window  Setting Interpreter options to -Wall in the Run/Debug configurations window   and all permutations, all to no avail. Is there a way to show all runtime warnings when running tests using pytest in PyCharm in the PyCharm Console window? EDIT: @Override12 When I select do not add "--no-header --no-summary -q" in advanced settings I get the following output:  D:\Projects\S\SHARK\development_SCE\cenv\python.exe "D:/Program Files (x86)/JetBrains/PyCharm 2020.3.4/plugins/python/helpers/pycharm/_jb_pytest_runner.py" --path D:\Projects\S\SHARK\development_SCE\cenv\Lib\site-packages\vistrails-3.5.0rc0-py3.9.egg\vistrails\packages\SHARK\analysis\tests\test_fairing_1_plus_k.py -- --jb-show-summary Testing started at 10:07 AM ...

However I would like to see all 278 warnings. When I run pytest from the command line outside PyCharm I get the same result. So it seems to be a pytest problem and it seems that it has nothing to do with PyCharm.

Answer: The solution is a combination of two things:  Setting 'do not add "--no-header --no-summary -q"' in advanced settings as @Override12 suggested. When the same warning is issued multiple times, only the first time is displayed. In my case solving the first warning reduced the number of warnings from 278 to 2.
