如何将变量从 pytest fixture 转移到实际测试？

Question

我有一个 pytest 依赖 setup/teardown 到 create/delete 运动流的夹具：

@pytest.fixture()
def clean_up_kinesis_test():
    stream_name = uuid.uuid4().hex
    api_utils.create_kinesis_stream('us-east-1', stream_name, 1)
    assert active
    yield
    api_utils.delete_kinesis_stream('us-east-1', stream_name)

@pytest.mark.usefixtures("clean_up_kinesis_test")
def test_func1():
    # Use the stream_name from the fixture to do further testing

@pytest.mark.usefixtures("clean_up_kinesis_test")
def test_func2():
    # Use the stream_name from the fixture to do further testing

有什么方法可以将 stream_name 从夹具传递到实际的 test_func1 和 test_func2？

我不能使用全局变量，因为每个测试都需要有自己的流来进行测试。

Answer 1

生成测试夹具的值并将夹具作为参数传递到每个测试中。

import pytest
import uuid

@pytest.fixture()
def clean_up_kinesis_test():
    stream_name = uuid.uuid4().hex
    yield stream_name

def test_func1(clean_up_kinesis_test):
    print(clean_up_kinesis_test)

def test_func2(clean_up_kinesis_test):
    print(clean_up_kinesis_test)
