1.pytest需要测试多个py文件，这些文件有一定的依赖关系，同时执行的时候，需要只执行一次初始化setup，结束再执行一次teardown；
2.多个py文件需要使用pytest的conftest.py,这个文件名是固定的，在同级目录还需要__init__.py；
3.由于setup这种经典的初始化方法只支持module,class.method,function,setup
module: 一个py文件只运行一次，里面可以是class和function；
class: 每个class执行一次；
method: class里面的每个函数执行一次；
function ： 每个函数执行一次（函数不在class中）；
setup: 最小层级，每个函数运行一次；在allure报告中，现在在Test body中；其他级别显示在的setup中；
4.经典初始化不支持多个py初始化，只能选用fixture;
scope值 ：默认是function；
session 多个py文件；
module 一个py文件里面多个class或function；
class： class级别；
function：函数级别；
由于我们是多个py所以，只能选择session；
yield 是setup和teardown分界线；
@pytest.fixture(scope="session")
def start_up_session():
try:
case_name = os.path.basename(__file__).replace(‘.py‘, ‘‘)
print(case_name + " start")
# yield 前面的是tearup的操作
yield case_name
# yield 后面的是teardown的操作
print(case_name + " finish")
autouse = True 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；
@pytest.fixture(scope="function", autouse=True)
def get_status():
case_name = os.path.basename(os.path.abspath(__file__)).replace(".py", "")
print(case_name + " begin")
yield 1 if case_name.isalnum() else 0
print(case_name + " finish")
# 不传参数get_tstus也会运行
def test_1():
print(1111)
def test_name():
print(2222)
if __name__ == "__mian__":
pytest.main(["-s", "test_base.py"])

autouse = True fixture里面有个参数autouse，默认是Fasle没开启的，需要显示调用；
import pytest
import os
# 默认autouse=Fasle
@pytest.fixture(scope="function")
def get_status():
case_name = os.path.basename(os.path.abspath(__file__)).replace(".py", "")
print(case_name + " begin")
yield 1 if case_name.isalnum() else 0
print(case_name + " finish")

5.fixture 需要返回值：用传参数调用：在函数参数中，插入fixture的参数；
import pytest
import os
@pytest.fixture(scope="function", autouse=True)
def get_status():
case_name = os.path.basename(os.path.abspath(__file__)).replace(".py", "")
print(case_name + " begin")
yield 1 if case_name.isalnum() else 0
print(case_name + " finish")
def test_1(get_status):
num = get_status

print(1111)
def test_name(get_status):
num = get_status
assert num < 1

6.fixture 不需要返回值：除了用传参数调用，还可以用@pytest.mark.usefixtures()；对class和函数都可以使用，记得和scope搭配；
import pytest
import os
@pytest.fixture(scope="function", autouse=True)
def get_status():
case_name = os.path.basename(os.path.abspath(__file__)).replace(".py", "")
print(case_name + " begin")
yield 1 if case_name.isalnum() else 0
print(case_name + " finish")
@pytest.mark.usefixtures("get_status")
def test_1():
print(1111)
@pytest.mark.usefixtures("get_status")
def test_name():
print(2222)
if __name__ == "__mian__":

7. 多个py文件使用conftest.py，名字固定，不要改；
同级需要有__init__.py；
千万不要通过import导入conftest，否则每个py文件都会运行一遍conftest.py, 无法起到多个py只执行一次作用；pytest执行的时候自动去读conftest.py配置；
import pytest import os # conftest.py @pytest.fixture(scope="session") def get_status(): case_name = os.path.basename(os.path.abspath(__file__)).replace(".py", "") print(case_name + " begin") yield 1 if case_name.isalnum() else 0 print(case_name + " finish")
import pytest import os # test_base 不传参数，不要返回值 @pytest.mark.usefixtures("get_status") def test_1(): print(1111) @pytest.mark.usefixtures("get_status") def test_name(): print(2222) if __name__ == "__mian__": pytest.main(["-s", "test_base.py"])
