定义作用于为function的fixture

import pytest
import time

@pytest.fixture(scope="function")
def func_header(request):
    print('\n-----------------')
    print('function    : %s' % request.function.__name__)
    print('time        : %s' % time.asctime())
    print('-----------------')
    return "fun"

@pytest.fixture(scope="module")
def mod_header(request):
    print('\n-----------------')
    print('module      : %s' % request.module.__name__)
    print('-----------------')
    return "mod"

case里接受参数

class TestDemo(object):
    def test_one(self, mod_header, func_header):
        print('in test_one()')
        print(mod_header)
        print(func_header)

    def test_two(self, mod_header, func_header):
        print('in test_two()')
        print(mod_header)
        print(func_header)
