Global Variables ​

pytest treats some global variables in a special manner when defined in a test module or conftest.py files.

collect_ignore ​

Tutorial: Customizing test collection

Can be declared in conftest.py files to exclude test directories or modules. Needs to be a list of paths (str, pathlib.Path or any os.PathLike).

collect_ignore = ["setup.py"]

collect_ignore = ["setup.py"]

collect_ignore_glob ​

Tutorial: Customizing test collection

Can be declared in conftest.py files to exclude test directories or modules with Unix shell-style wildcards. Needs to be list[str] where str can contain glob patterns.

collect_ignore_glob = ["*_ignore.py"]

collect_ignore_glob = ["*_ignore.py"]

pytest_plugins ​

Tutorial: Requiring/Loading plugins in a test module or conftest file

Can be declared at the global level in test modules and conftest.py files to register additional - plugins. Can be either a str or Sequence[str].

pytest_plugins = "myapp.testsupport.myplugin"

pytest_plugins = "myapp.testsupport.myplugin"

pytest_plugins = ("myapp.testsupport.tools", "myapp.testsupport.regression")

pytest_plugins = ("myapp.testsupport.tools", "myapp.testsupport.regression")

pytestmark ​

Tutorial: Marking whole classes or modules

Can be declared at the global level in test modules to apply one or more marks to all test - functions and methods. Can be either a single mark or a list of marks (applied in left-to-right - order).

import pytest

pytestmark = pytest.mark.webtest

import pytest

pytestmark = pytest.mark.webtest

import pytest

pytestmark = [pytest.mark.integration, pytest.mark.slow]

import pytest

pytestmark = [pytest.mark.integration, pytest.mark.slow]
