Question

在pytest中，我试图找出是否有可能将对象或变量从测试功能传递到“功能范围”灯具（传递至灯具设置或拆卸）

Answer 1

您可以按以下方式与灯具进行交互，但不在设置或拆卸中：

代码

import pytest

class FixtureStack():
    def __init__(self):
        self.messages = []

    def __str__(self):
        return f'messages={self.messages}'

    def push(self, msg):
        self.messages.append(msg)


@pytest.fixture(scope='function')
def stack():
    yield FixtureStack()


def test_1(stack):
    print(stack)
    stack.push('msg_1')
    print(stack)
    assert stack.messages == ['msg_1']


def test_2(stack):
    print(stack)
    stack.push('msg_2')
    print(stack)
    assert stack.messages == ['msg_2']

Pytest执行：

$ pytest -v driver.py -s

是否可以将对象或变量从测试功能传递到功能夹具？
