faker fixture

✓ def test_example(faker):

✗ from faker import Faker; fake = Faker()

pytest-faker provides the 'faker' fixture directly; manual Faker instantiation bypasses the plugin and may cause test isolation issues.

Write a test that uses the 'faker' fixture to generate fake data. No imports needed beyond pytest.

import pytest def test_name(faker): name = faker.name() assert isinstance(name, str) def test_email(faker): email = faker.email() assert '@' in email

Debug

Known issues

breakingVersion 1.0 used 'fake' fixture; version 2.0 changed to 'faker'.

fix

Rename fixture usage from 'fake' to 'faker'.

affects: 1.x -> 2.0+

deprecatedFaker's 'seed' method is deprecated; use 'seed_instance' or configure via pytest-faker's seed fixture.

fix

Use 'faker.seed_instance(12345)' or the 'faker_seed' fixture.

affects: All versions using Faker < 18.0

gotchaThe 'faker' fixture uses a new Faker instance per test by default, but seeding with 'faker_seed' can cause shared state if not careful.

fix

Use 'faker_seed' fixture per test function to control reproducibility without cross-test contamination.

affects: All versions
