无法从pytest.fixture获取数据，而是获取数据位置

Question

i am testing in pytest. here is my code

file1.py

def pytest_addoption(parser):
     parser.addoption('--uid')

@pytest.fixture
def login_id(request,pytestconfig):
    user_id = pytestconfig.getoption('--uid')

    return user_id

what it does is take the cli argument in pytest

file2.py

@pytest.fixture 
def func(): 
      login(login_id)
      return session()

when i am performing the test on a module which require the session to be created login_id is giving me data as

< function login_id at 0x00000000092F79D8>

i am unable to get this data , how to get the value which i am passing in cli argument.

i am using pycharm, python3.5 .

cli parameter as --uid username

i am not getting the username in login fucntion but instead getting the location of data.

thanks and regards

If you want to use a fixture's value in another fixture, just pass it as a parameter:

@pytest.fixture
def login_id(request):
    ...
    return ...

@pytest.fixture 
def func(login_id): 
      login(login_id)
      return session()

Suggestion aside: you don't need the pytestconfig fixture since you are already using request . You can get the config via request.config in the login_id fixture:

@pytest.fixture
def login_id(request):
    user_id = request.config.getoption('--uid')
    return user_id
