pytest plugin with powerful fixtures
Adds a number of shorthands for fixtures and other helpers for easier testing:
You can instal pytest-power with pip:
pip install pytest-power
A shorthand for pytest-mock's
from myapp import App def test_app_run(patch): patch.object(App, 'run') App.run() assert App.run.call_count == 1
You can pass keywords arguments as usual:
from myapp import App def test_app_run(patch): patch.object(App, 'run', return_value='running') assert App.run() == 'running'
__init__ a bit simpler:
from myapp import App def test_app_init(patch): patch.init(App) app = App() assert isinstance(app, App)
Instances patched in this way do not have properties that are set in
so they have to be set again by hand.
Keyword arguments are passed to underlying
patch.object, and autospec is
enabled by default.
A shorthand to patch many properties of the same object:
from myapp import App def test_app_run_called_by_run(patch): patch.many(App, ['run', 'called_by_run']) App.run() assert App.called_by_run.call_count == 1
Keyword arguments are again passed to underlying
patch.object, and autospec
is enabled by default.
A shorthand to patch every non-magic property. Useful when patch.many gets too long!
from myapp import App def test_app_run_called_by_run(patch): patch.everything(App) App.run() assert App.called_by_run.call_count == 1
No keyword arguments support...because I forgot!
