Python package for mocking uuid
from freeze_uuid import freeze_uuid
@freeze_uuid ('12af6b44-8181-11ee-b890-628ab7cd4d99' )
def test_uuid ():
assert str (uuid .uuid1 ()) == '12af6b44-8181-11ee-b890-628ab7cd4d99'
assert str (uuid .uuid4 ()) == '12af6b44-8181-11ee-b890-628ab7cd4d99'

assert str (uuid .uuid4 ()) == '00000000-0000-0000-0000-000000000000'
@pytest .mark .asyncio
@freeze_uuid ('12af6b44-8181-11ee-b890-628ab7cd4d99' )
async def test_uuid_async ():
assert str (uuid .uuid1 ()) == '12af6b44-8181-11ee-b890-628ab7cd4d99'
assert str (uuid .uuid4 ()) == '12af6b44-8181-11ee-b890-628ab7cd4d99'
Also you can use list of uuids for multiple usage
@freeze_uuid (['12af6b44-8181-11ee-b890-628ab7cd4d99' , '12af6b44-8181-11ee-b890-628ab7cd4d98' ])
def test_uuid_list ():
assert str (uuid .uuid1 ()) == '12af6b44-8181-11ee-b890-628ab7cd4d99'
assert str (uuid .uuid4 ()) == '12af6b44-8181-11ee-b890-628ab7cd4d98'
assert str (uuid .uuid4 ()) == '12af6b44-8181-11ee-b890-628ab7cd4d98'
assert str (uuid .uuid4 ()) == '12af6b44-8181-11ee-b890-628ab7cd4d98'
Since library mocks uuid.UUID class, it can be used with all libraries, that support UUID class, i.e. uuid7
from uuid_extensions import uuid7
@freeze_uuid (TEST_UUID )
def test_uuid_7 ():
assert str (uuid7 ()) == TEST_UUID
With freeze_uuid context manager you can create tests with pytest parametrize
from freeze_uuid import freeze_uuid_manager
@pytest .mark .parametrize (
['expected_result' , 'freeze_data' ],
[
pytest .param (
TEST_UUID_2 ,
[TEST_UUID_2 ],
),
pytest .param (
TEST_UUID_3 ,
[TEST_UUID_3 ],
),
pytest .param (
TEST_UUID_4 ,
[TEST_UUID_4 ],
),
pytest .param (
TEST_UUID_5 ,
[TEST_UUID_5 ],
),
]
)
def test_parametrize (expected_result , freeze_data ):
with freeze_uuid_manager (freeze_data ):
assert str (uuid .uuid4 ()) == expected_result
