how to get return value from pytest fixture in a function so I don't need to call this function with...

I have the following fixture in conftest.py that returns an environment settings dictionary like user, password etc:

@pytest.fixture

def envparams(request):

    env = request.config.getoption("--env")

    return env_params[env]

Then I have module like:

def request_master_url(envparams):

    cje_master_url = envparams['url']+'/'+test_master

    cje_user = envparams['user']

    cje_pass = envparams['password']

    local = testinfra.get_host("ssh://localhost")

    results = local.command(

                        'curl -L -I --user '+cje_user+':'

                        + cje_pass+' '+cje_master_url+'| grep HTTP

                        |tail -1').stdout

    if '200 OK' in results:

        return True

    else:

        return False

and a test that uses this module like:

def test_cje_high_availability(envparams, env_option, script_loc):

    workstation = testinfra.get_host('ssh://'+testinfra_hosts[0])

    if not security.request_master_url(envparams):

        print(test_master+' - is not availablen')

        create_team_master(test_master, envparams, script_loc)

Can I get rid of the envparams parameter from module function somehow so I can call it without additional parameter?
like:

security.request_master_url(envparams)

I only need to setup this fixture once in a session. I tried to use:

@pytest.mark.usefixtures('envparams')

def request_master_url():

But, I am not sure how to get values returned from this fixture.

Why not making a fixture out of request_master_url?

it's some solution, but I have many more functions like this one that are also using envparams fixture. I think it would be perhaps, better to create a global parameter in conftest.py and set it to envparams fixture for a session. I'll just read that from my module functions and no additional parameter would be needed to call from test functions.

Thing is, you can't apply pytest machinery to normal functions per se. If request_master_url should be a function and is used in tests only, you can get the env via pytest.config.getoption('--env') in the function directly, so you don't need to pass the envparams argument. Is this suitable to your needs?

yes, this was very helpfull actually. Implemented today.

Well, I've done as hoefling suggested.

Created small function in conftest.py:

def get_env_params():

    env_name = pytest.config.getoption("--env")

    return env_params[env_name]

and call it from my module functions where needed. Example function looks like below:

def request_master_url(team_id):

    envparams = get_env_params()

    cje_master_url = envparams['url']+'/'+team_id

    cje_user = envparams['user']

    cje_pass = envparams['password']

    local = testinfra.get_host("ssh://localhost")

    results = local.command(

                        'curl -L -I --user '+cje_user+':'

                        + cje_pass+' '+cje_master_url+'| grep HTTP

                        |tail -1').stdout

    if '200 OK' in results:

        return True

    else:

        return False

removed unnecessary fixture from many more functions and was able to clean my code a lot. Thanks!
