`MatplotlibDeprecationWarning` running `Testing` with `PythonDebugger` #1727

Closed StefanieSenger closed 2 weeks ago

StefanieSenger commented 2 weeks ago

Type: Bug

Behaviour

I am getting MatplotlibDeprecationWarning that causes an error with test_warn failed when I run this test with the PythonDebugger in the Testing extension.

versions: pytest==8.3.1 matplotlib==3.9.2

Steps to reproduce:

import warnings
import pytest

def f():
    warnings.warn("Test", UserWarning)

def test_warn():
    with pytest.warns(UserWarning, match="Test"):
        f()

Setting a breakpoint in the line of with pytest.warns(UserWarning, match="Test"): and run in debug-mode. The debugger raises an error:

Diagnostic data

Traceback:

/home/stefanie/code/scikit-learn_dev/scikit-learn/sklearn/test_warn.py::test_warn failed: def test_warn():
>       with pytest.warns(UserWarning, match="Test"):

I would have expected not to see this warning and be able to continue with the debugging.

Running the test with Testing without debug points or running the tests with pytest on the terminal works just fine.
