如何在夹具外部使用安装夹具中的变量

Question

我想在 setupone 夹具外部使用产品变量。我想在 test_title.py in skipif 标记中使用它进行条件跳过（运行测试用例，如果产品名称满足）。 conftest.py

def pytest_addoption(parser):
    parser.addoption("--browser_name", action="store", default="chrome")
    parser.addoption("--env", action="store", default="Production")
    parser.addoption("--product_name", nargs = '*', type = str, action ="store", default="chitale")

products_list = getProductList()

@pytest.fixture(scope='class', params = products_list)
def setupone(request):
    browser = request.config.getoption("browser_name")
    env_name = request.config.getoption("env")
    product = request.param

(getProductList() returns ["product1", "product2", "product3"] 存储在 product_list)

BaseOne.py

@pytest.mark.usefixtures("setupone")
class BaseOne:
    pass

test_title.py

from conftest import prod

class TestStoreTitle(BaseOne):

    @pytest.mark.skipif(prod not in ["product1", "product2", "product3"], reason="test case doesn't apply for desired product")
    def test_Store_Title(self):
        pass

我想在函数之外使用 setupone 的产品，例如：

def pytest_addoption(parser):
    parser.addoption("--browser_name", action="store", default="chrome")
    parser.addoption("--env", action="store", default="Production")
    parser.addoption("--product_name", nargs = '*', type = str, action ="store", default="chitale")

products_list = getProductList()

@pytest.fixture(scope='class', params = products_list)
def setupone(request):
    browser = request.config.getoption("browser_name")
    env_name = request.config.getoption("env")
    product = request.param

prod = product

Answer 1

另一种方法是仅从其固定装置访问产品 setupone。

Return 夹具的产品价值 setupone
定义一个 autouse-fixture，它将通过 get_closest_marker() 自动处理产品的跳过标记，下面是 skip_product_not_in_list
将求购商品列表传给大关skip_product_not_in_list
如果 setupone 的当前产品不在想要的列表中，请通过 pytest.skip()

import pytest

products_list = ["product1", "product2", "product3"]


@pytest.fixture(scope='class', params=products_list)
def setupone(request):
    product = request.param
    return product


@pytest.fixture(autouse=True)
def skip_non_applicable_products(request, setupone):
    if product_marker := request.node.get_closest_marker("skip_product_not_in_list"):
        if setupone not in product_marker.args[0]:
            # Option 1
            # pytest.skip(product_marker.kwargs.get('reason'))
            # Option 2
            pytest.skip(f"{product_marker.kwargs.get('reason') or 'Skipped'} {setupone}")


def test_Store_Title_all_products(setupone):
    print("test_Store_Title_all_products:", setupone)


@pytest.mark.skip_product_not_in_list(["product1", "product3"], reason="test case doesn't apply for desired product")
def test_Store_Title_skip_products(setupone):
    print("test_Store_Title_skip_products:", setupone)

输出

$ pytest -rPS test_src.py
============================================== PASSES ===============================================
______________________________ test_Store_Title_all_products[product1] ______________________________
--------------------------------------- Captured stdout call ----------------------------------------
test_Store_Title_all_products: product1
_____________________________ test_Store_Title_skip_products[product1] ______________________________
--------------------------------------- Captured stdout call ----------------------------------------
test_Store_Title_skip_products: product1
______________________________ test_Store_Title_all_products[product2] ______________________________
--------------------------------------- Captured stdout call ----------------------------------------
test_Store_Title_all_products: product2
______________________________ test_Store_Title_all_products[product3] ______________________________
--------------------------------------- Captured stdout call ----------------------------------------
test_Store_Title_all_products: product3
_____________________________ test_Store_Title_skip_products[product3] ______________________________
--------------------------------------- Captured stdout call ----------------------------------------
test_Store_Title_skip_products: product3
====================================== short test summary info ======================================
SKIPPED [1] test_src.py:19: test case doesn't apply for desired product product2
============================== 5 passed, 1 skipped, 1 warning in 0.08s ==============================

对于test_Store_Title_all_products，它测试了所有产品。对于我们定义自定义列表的 test_Store_Title_skip_products，我们可以看到它跳过了 "product2"，因为它不在列表中。
