How to change the default event loop scope of all tests

The :ref:`configuration/asyncio_default_test_loop_scope` configuration option sets the default event loop scope for asynchronous tests. The following code snippets configure all tests to run in a session-scoped loop by default:

[pytest]
asyncio_default_test_loop_scope = session

[tool.pytest.ini_options]
asyncio_default_test_loop_scope = "session"

[tool:pytest]
asyncio_default_test_loop_scope = session

Please refer to :ref:`configuration/asyncio_default_test_loop_scope` for other valid scopes.
