Question

Running the code below I get

E TypeError: unbound method make_request() must be called with A instance as first argument (got str instance instead)

I dont want to set make_request method as static, I want to call it from an instance of an object.

The example http://pytest.org/latest/fixture.html#fixture-function

# content of ./test_smtpsimple.py
import pytest

@pytest.fixture
def smtp():
    import smtplib
    return smtplib.SMTP("merlinux.eu")

def test_ehlo(smtp):
    response, msg = smtp.ehlo()
    assert response == 250
    assert "merlinux" in msg
    assert 0 # for demo purposes

My code

""" """
import pytest


class  A(object):
    """  """
    def __init__(self, name ):
        """ """
        self._prop1 = [name]


    @property
    def prop1(self):
        return self._prop1  

    @prop1.setter
    def prop1(self, arguments):
        self._prop1 = arguments

    def make_request(self, sex):
        return 'result'

    def __call__(self):
        return self


@pytest.fixture()
def myfixture():
    """ """
    A('BigDave')
    return A

def test_validateA(myfixture):
    result = myfixture.make_request('male')
    assert result =='result'

Answer 1

You can try replacing your last two methods as: –

@pytest.fixture()
def myfixture():
    """ """
    return A('BigDave')

def test_validateA(myfixture):
    result = myfixture().make_request('male')
    assert result =='result'

myfixture is the function object. To invoke the function you need a bracket on it. So, myfixture().

Now in myfixture() method, return A again returns the class object. In order to return an instance of class A, on which you will call your method, you need to return either A() or just return the A('BigDave') you are using there.

So, now your test_validateA method will get an instance of class A from myfixture method, on which you are invoking the method, thus passing the self as first argument.
