Question

pytest正在为每个测试功能调用模块级夹具预计每个模块只能调用一次夹具

#content of test_fin.py
import pytest
import time
import logging


@pytest.fixture
def do_setup_tear(scope="module"):
    logging.getLogger().info('doing setup stuff if needed')
    yield None
    logging.getLogger().info('teardown')


def test_do_this():
    time.sleep(5) 
    assert True

def test_do_that(do_setup_tear):
    time.sleep(5)
    assert True

def test_do_thing(do_setup_tear):
    time.sleep(5) 
    assert True

实际结果：

我在这里错过了什么吗？如果我将scope="module"修改为`scope =“ function”，我会得到相同的输出

Answer 1

在定义灯具范围时有一个小错误。现在，您将范围作为参数传递给Fixture函数。应该在@pytest.fixture行上使用它。

@pytest.fixture(scope="module")
def do_setup_tear():
    logging.getLogger().info('doing setup stuff if needed')
    yield None
    logging.getLogger().info('teardown')

如果我将scope =“ module”修改为scope =“ function”，我会得到相同的输出

这是因为现在夹具范围为function，这是默认值，除非用户指定。

每个测试功能都需要调用模块作用域的夹具
