前言
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,每次都传这个参数,会比较麻烦。
fixture里面有个参数autouse,默认是Fasle没开启的,可以设置为True开启自动使用fixture功能,这样用例就不用每次都去传参了
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
用例传fixture参数
方法一:先定义start功能,用例全部传start参数,调用该功能
#!/usr/bin/env/python
# -*-coding:utf-8-*- import pytest @pytest.fixture(scope="function")
def start(request):
print('\n-----开始执行function----') def test_a(start):
print("-------用例a执行-------") class Test_aaa(): def test_01(self, start):
print('-----------用例01--------------') def test_02(self, start):
print('-----------用例02------------')
运行结果:

装饰器usefixtures
方法二:使用装饰器@pytest.mark.usefixtures()修饰需要运行的用例
#!/usr/bin/env/python
# -*-coding:utf-8-*-
import pytest @pytest.fixture(scope="function")
def start(request):
print('\n-----开始执行function----') @pytest.mark.usefixtures("start")
def test_a():
print("-------用例a执行-------") @pytest.mark.usefixtures("start")
class Test_aaa(): def test_01(self):
print('-----------用例01--------------') def test_02(self):
print('-----------用例02------------')
运行结果:

设置autouse=True
方法三、autouse设置为True,自动调用fixture功能
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
open_home设置scope为function级别,每个用例前都调用一次,自动使用
#!/usr/bin/env/python
# -*-coding:utf-8-*-
import pytest @pytest.fixture(scope="module", autouse=True)
def start(request):
print('\n-----开始执行moule----')
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 \n--------回到首页--------" % request.function.__name__) def test_01():
print('-----------用例01--------------\n') def test_02():
print('-----------用例02------------\n')
运行结果:

写在class里面也是一样的
#!/usr/bin/env/python
# -*-coding:utf-8-*-
import pytest @pytest.fixture(scope="module", autouse=True)
def start(request):
print('\n-----开始执行moule----')
print('module : %s' % request.module.__name__)
print('----------启动浏览器---------')
yield
print("------------结束测试 end!-----------") class Test_aaa():
@pytest.fixture(scope="function", autouse=True)
def open_home(self, request):
print("function:%s \n--------回到首页--------" % request.function.__name__) def test_01(self):
print('-----------用例01--------------\n') def test_02(self):
print('-----------用例02------------\n')
