如何在pytest夹具中获取来电者姓名？

Question

假设我们有：

@pytest.fixture()
def setup():
    print('All set up!')
    return True

def foo(setup):
    print('I am using a fixture to set things up')
    setup_done=setup

我正在寻找一种从安装夹具中了解调用函数名称（在本例中为 foo）的方法。

到目前为止我已经尝试过：

import inspect

@pytest.fixture()
def setup():
    daddy_function_name = inspect.stack()[1][3]
    print(daddy_function_name)

    print('All set up!')
    return True

但是打印出来的是：call_fixture_func

如何通过打印 daddy_function_name 得到 foo？

Answer 1

您可以在自己的夹具中使用the built-in request fixture：

The request fixture is a special fixture providing information of the requesting test function.

Its node attribute 是

Underlying collection node (depends on current request scope).

import pytest


@pytest.fixture()
def setup(request):
    return request.node.name


def test_foo(setup):
    assert setup == "test_foo"
