Pytest: Fixture variable not found

I am new to pytest and I have written a test function with fixture but I am receiving an error that fixture variable is not found. Here is the code:

@pytest.fixture(scope="module")
def func1(arg1,arg2):
     return arg1 + arg2

def test_func1(func1):
     assert func1== 4

When I run this file, I get the error E fixture arg1 not found. If I define arg1 and arg2 globally and not pass them through function, this will work fine, but how can I pass an argument to fixture function.

You need to define arg1 and arg2 as fixtures themselves, then it should work. Do as follows:

@pytest.fixture(scope="module")
def argX():
    # return 'enter definition of argX here'

It's not completely clear how you want the arguments to be passed to the fixture. I can only guess that they are supposed to be parameters of your test function in which case you need to define them in @pytest.mark.parametrize and set them as indirect so that they are passed to func1 fixture:

import pytest

@pytest.fixture()
def func1(request):
     return request.param[0] + request.param[1]

@pytest.mark.parametrize('func1', [(1, 3)], indirect=True)
def test_func1(func1):
     assert func1 == 4
