Except the system mentioned HOOK Out of function , You can also customize HOOK To achieve the desired function .

First create a py file , It defines its own HOOK function , The main pytest Inside hook Function must be in pytest start .

#myhook.py


def pytest_myhook(user):
    """ Customize HOOK function """


def pytest_myhook2():
    """ Customize HOOK function """

Secondly, create your own plug-in class ,user Class __init__ Method , Bring in when registering the hook pytest Of config To configure . Set the hook entry in this method ：self

.config.hook.pytest_myhook().

# Plug in class 
class user:
    name = "herry"
    age = 18


    def __init__(self, config):
        self.config = config
        self.config.hook.pytest_myhook(user=self)
        self.config.hook.pytest_myhook2()




@pytest.mark.A
def test_B():
    print("BBB")




if __name__ == "__main__":
    pytest.main([("pytest Module sharing hook2.py"), ("-s"), ("-m=A")])

Last in conftest.py Register the hook and reference in the file to implement it . Among them, the registration method should be put in the front .

Add the structure first , Registering plug-ins ,

def pytest_addhooks(pluginmanager):
    from . import myhook


    pluginmanager.add_hookspecs(myhook)




def pytest_configure(config):
    config.user_ = user(config)
    config.pluginmanager.register(config.user_)




def pytest_myhook(user):
    print("username------%s"%user.name)
    print("age------%s" % user.age)


def pytest_myhook2():
    print("myhook2")
