Pytest Fixture参数讲解及使用

@pytest.fixture(scope = "function",params=None,autouse=False,ids=None,name=None)

@pytest.fixture() 
#或者
@pytest.fixture(scope='function')

import pytest
# fixture函数(类中) 作为多个参数传入
@pytest.fixture()
def login():
    print("打开浏览器")
    a = "account"
    return a
    
@pytest.fixture()
def logout():
    print("关闭浏览器")

class TestLogin:
    #传入lonin fixture
    def test_001(self, login):
        print("001传入了loging fixture")
        assert login == "account"

    #传入logout fixture
    def test_002(self, logout):
        print("002传入了logout fixture")

    def test_003(self, login, logout):
        print("003传入了两个fixture")

    def test_004(self):
        print("004未传入仍何fixture哦")

if __name__ == '__main__':
    pytest.main()

import pytest
# fixtrue作为参数，互相调用传入
@pytest.fixture()
def account():
    a = "account"
    print("第一层fixture")
    return a
    
#Fixture的相互调用一定是要在测试类里调用这层fixture才会生次，普通函数单独调用是不生效的
@pytest.fixture()   
def login(account):
    print("第二层fixture")

class TestLogin:
    def test_1(self, login):
        print("直接使用第二层fixture,返回值为{}".format(login))

    def test_2(self, account):
        print("只调用account fixture,返回值为{}".format(account))
