平常写自动化用例会写一些前置的 fixture 操作,用例需要用到就直接传该函数的参数名称就行了。当用例很多的时候,每次都传返个参数,会比较麻烦。
fixture 里面有个参数 autouse,默讣是 Fasle 没开启的,可以设置为True 开启自动使用 fixture 功能,返样用例就丌用每次都去传参了
调用 fixture 三种方法
1.函数或类里面方法直接传 fixture 的函数参数名称
2.使用装饰器@pytest.mark.usefixtures()修饰
3.autouse=True 自动使用
方法一:autouse 设置为 True,自动调用 fixture 功能
1.start 设置 scope 为 module 级别,在当前.py 用例模块只执行一次,autouse=True 自动使用
2.open_home 设置 scope 为 function 级别,每个用例前都调用一次,自动使用
import pytest
@pytest.fixture(scope="module",autouse=True)
def start(request):
print("
----开始执行module------")
print('module : %s'% request.module.__name__)
print('------启动浏览器-------')
yield
print("------结束测试 end!----------")
@pytest.fixture(scope="function",autouse=True)
def open_home(request):
print("function:%s
--回到首页--"% request.function.__name__)
def test_01():
print('----用例01-----')
def test_02():
print('----用例02-----')
if __name__ == '__main__':
pytest.main(["-s","test_hest.py"])
运行结果:

方法二:使用装饰器@pytest.mark.usefixtures()修饰需要运行的用例
import pytest
@pytest.fixture(scope='function')
def start(request):
print('==========开始执行function===========')
@pytest.mark.usefixtures('start')
def test_a():
print('==============执行用例a===============')
@pytest.mark.usefixtures('start')
class TestCase():
def test_01(self):
print('============用例01============')
def test_02(self):
print('============用例02============')
if __name__=='__main__':
pytest.main(["-s", "test_hest.py"])
运行结果:
============================= test session starts =============================

==============执行用例a===============
.==========开始执行function===========
============用例01============

方法三:先定义 start 功能,用例全部传 start 参数,调用该功能
import pytest
@pytest.fixture(scope='function')
def start(request):
print('
=========开始执行function============')
def test_a(start):
print('=======用例a==========')
class TestCase():
def test_01(self, start):
print('=======用例01=========')
def test_02(self, start):
print('=======用例02=========')
if __name__=='__main__':
pytest.main(["-s", "test_hest.py"])
