Pytestを使うときに何らかの理由でmock.patchを動作させることができません。それは単にパッチを当てません。私はそれを間違って使用していますか、何か私の設定がうんざりしていますか?模擬テスト/ pytest-mockを使ったPytest
base.py
def foo():
return 'foo'
def get_foo():
return foo()
test_base.py
import pytest
import mock
from pytest_mock import mocker
from base import get_foo
@mock.patch('base.foo')
def test_get_foo(mock_foo):
mock_foo.return_value = 'bar'
assert get_foo() == 'bar'
def test_get_foo2(mocker):
m = mocker.patch('base.foo', return_value='bar')
assert get_foo() == 'bar'
def test_get_foo3():
with mock.patch('base.foo', return_value='bar') as mock_foo:
assert get_foo() == 'bar'

pytest_mockを使ってオブジェクトをモックするさまざまな方法を示してくれてありがとう。 –
