My session fixture can raise ExceptionGroup and I see huge traceback which grows unlimitedly from test to test.

pip list:

iniconfig 2.0.0  
packaging 24.0   
pluggy    1.4.0  
pytest    8.1.1

Operation system: macOS 14.3
Python: 3.12.0

Example:

import pytest

@pytest.fixture(scope='session', autouse=True)
def f1():
    raise ExceptionGroup('', [ValueError()])

def test_smth1():
    pass

def test_smth2():
    pass

def test_smth3():
    pass

With such code I get 495 lines of logs:

Interesting, thanks for the report.

Problem

First, this is actually not specific to ExceptionGroup, this happens for every exception, it's just that we haven't implemented pretty-printing for ExceptionGroup yet so it's more visible. But with --tb=native can see the same thing for Exception as well.

So what happens is, when the session fixture is first requested by the first test, it is executed, raises, and the exception is cached as the result of the fixture. When the next test requests the fixture, we see the cached exception and re-raise it.

But in python, exception objects are mutable; whenever you raise an exception, it appends entries to the traceback. So on every raise of the cached exception, the traceback gets longer and longer...

Example 

import traceback

def bad():
    1 / 0

cache = None
def foo():
    global cache
    if cache is not None:
        raise cache
    try:
        bad()
    except Exception as exc:
        cache = exc
        raise

try:
    foo()
except Exception:
    traceback.print_exc()

print('\n')
try:
    foo()
except Exception:
    traceback.print_exc()

print('\n')
try:
    foo()
except Exception:
    traceback.print_exc()

Output:

Traceback (most recent call last):
  File "/home/ran/src/pytest/yy.py", line 18, in <module>
    foo()
  File "/home/ran/src/pytest/yy.py", line 12, in foo

  File "/home/ran/src/pytest/yy.py", line 4, in bad

Solution

The solution is to keep the original traceback, and re-raise with it.

Turns out, this is how it was done in pytest < 8.0, before I mindlessly broke it in #11208 / 9d0ddb4. So I need to revert this.

BTW, there is another place where we do this raising of cached exception thing, in SetupState.setup(). This one I also broke, but a few years earlier, in 978b315. I will fix this as well.
