pytest-deprecated-yield-fixture (PT020)

Derived from the flake8-pytest-style linter.

What it does

Checks for pytest.yield_fixture usage.

Why is this bad?

pytest.yield_fixture is deprecated. pytest.fixture should be used instead.

Example

import pytest


@pytest.yield_fixture()
def my_fixture():
    obj = SomeClass()
    yield obj
    obj.cleanup()

Use instead:

import pytest


@pytest.fixture()
def my_fixture():
    obj = SomeClass()
    yield obj
    obj.cleanup()
