pytypest 0.1.0

Type-safe and maintainable fixtures and parametrization for pytest.

pytypest

Type-safe and maintainable fixtures and parametrization for pytest.

Features:

• 100% type safe.
• Great IDE integration, go-todefinition always takes you in the right place.
• Test parametrization that is redable even with many arguments.
• Plug-and-play integration with pytest.
• No vendor-lock, you can use only the features you need and don't touch the rest.
• Fixtures can be cached, and you are in control of for how long.
• Fixtures can accept arguments.

Installation

python3 -m pip install pytypest

Usage

Fixtures are regular helper functions that yield their result and do teardown afterwards:

from typing import Iterator
from pytypest import fixture

@fixture
def get_user(anonymous: bool) -> Iterator[User]:
    u = User(anonymous=anonymous)
    u.save()
    yield u
    u.delete()

def test_user() -> None:
    u = get_user(anonymous=False)
    assert u.anonymous is False

Compared to built-in pytest fixtures, these are explicit, type-safe, can accept arguments, support go-to-definition in IDE, and can be used as context managers. And like pytest fixtures, they are cached and can be scoped to the module or the whole session.
