要以编程方式组合上下文管理器,我使用以下代码:
== helpers.py ==
from contextlib import nested
import mock
def multiple_patch(obj_to_be_patch, *methods):
return nested(
*[mock.patch.object(obj_to_be_patch, method) for method in methods]
)
== tests.py ==
def test_foo(self):
with helpers.multiple_patch(Foo, "method1", "method2", "method3", "method3") as mocks:
mock_method1 = mocks[0]
....
# asserts on mocks
