pytest 15 fixture之autouse=True
前言
平常寫自動(dòng)化用例會(huì)寫一些前置的fixture操作,用例需要用到就直接傳該函數(shù)的參數(shù)名稱就行了。當(dāng)用例很多的時(shí)候,每次都傳這個(gè)參數(shù),會(huì)比較麻煩。
fixture里面有個(gè)參數(shù)autouse,默認(rèn)是Fasle沒(méi)開(kāi)啟的,可以設(shè)置為True開(kāi)啟自動(dòng)使用fixture功能,這樣用例就不用每次都去傳參了
調(diào)用fixture三種方法
-
1.函數(shù)或類里面方法直接傳fixture的函數(shù)參數(shù)名稱
-
2.使用裝飾器@pytest.mark.usefixtures()修飾
-
3.autouse=True自動(dòng)使用
-
用例傳fixture參數(shù)
方法一:先定義start功能,用例全部傳start參數(shù),調(diào)用該功能
#!/usr/bin/env/python # -*-coding:utf-8-*-import pytest@pytest.fixture(scope="function") def start(request):print('\n-----開(kāi)始執(zhí)行function----')def test_a(start):print("-------用例a執(zhí)行-------")class Test_aaa():def test_01(self, start):print('-----------用例01--------------')def test_02(self, start):print('-----------用例02------------')運(yùn)行結(jié)果:
============================= test session starts ============================== platform darwin -- Python 3.7.0, pytest-3.9.1, py-1.7.0, pluggy-0.8.0 rootdir: /Users/newcomer/gitByMyself, inifile: plugins: datadir-1.2.1, allure-adaptor-1.7.10collected 3 itemspython_work_apple/pytest_package/fixtureDemo/test_01.py -----開(kāi)始執(zhí)行function---- .-------用例a執(zhí)行------------開(kāi)始執(zhí)行function---- .-----------用例01-------------------開(kāi)始執(zhí)行function---- .-----------用例02------------[100%]=========================== 3 passed in 0.02 seconds ===========================裝飾器usefixtures
方法二:使用裝飾器@pytest.mark.usefixtures()修飾需要運(yùn)行的用例
#!/usr/bin/env/python # -*-coding:utf-8-*- import pytest@pytest.fixture(scope="function") def start(request):print('\n-----開(kāi)始執(zhí)行function----')@pytest.mark.usefixtures("start") def test_a():print("-------用例a執(zhí)行-------")@pytest.mark.usefixtures("start") class Test_aaa():def test_01(self):print('-----------用例01--------------')def test_02(self):print('-----------用例02------------')運(yùn)行結(jié)果:
============================= test session starts ============================== platform darwin -- Python 3.7.0, pytest-3.9.1, py-1.7.0, pluggy-0.8.0 rootdir: /Users/newcomer/gitByMyself, inifile: plugins: datadir-1.2.1, allure-adaptor-1.7.10collected 3 itemspython_work_apple/pytest_package/fixtureDemo/test_02.py -----開(kāi)始執(zhí)行function---- .-------用例a執(zhí)行------------開(kāi)始執(zhí)行function---- .-----------用例01-------------------開(kāi)始執(zhí)行function---- .-----------用例02------------[100%]=========================== 3 passed in 0.02 seconds =========================== Process finished with exit code 0設(shè)置autouse=True
方法三、autouse設(shè)置為True,自動(dòng)調(diào)用fixture功能
-
start設(shè)置scope為module級(jí)別,在當(dāng)前.py用例模塊只執(zhí)行一次,autouse=True自動(dòng)使用
-
open_home設(shè)置scope為function級(jí)別,每個(gè)用例前都調(diào)用一次,自動(dòng)使用
運(yùn)行結(jié)果:
