The attachments are not in the Nunit report when using pytest-xdist

[anastasia-vlasova-gmg]

The environment:

• pytest=8.2.2
• pytest-nunit=1.0.7
• pytest-xdist=3.6.1
• python=3.10.8

The script:

import pytest

@pytest.mark.parametrize("params", [(1, 1),(2, 1)])
def test_temp(params, add_nunit_attachment):

    p = f"{str(params[0])}.txt"
    with open(p, "tw") as f:
        f.write("")
    add_nunit_attachment(p, p)
    assert params[0] == params[1]

The script when run without arguments produces test-output.xml containing:

<attachments>
  <attachment>
    <filePath>1.txt</filePath>
    <description>1.txt</description>
  </attachment>
</attachments>

as expected.

When run with -n 2 (2 xdist workers) produces test-output.xml with no attachments.

I don't see this behavior mentioned in the known limitations at the moment.
We use pytest-azurepipelines to run tests in CI and publishing attachments of the failing tests resulting files is a very useful instrument of the test failure diagnostics.
