My Base class contains following code:

from selenium import webdriver
import pytest
import unittest

@pytest.fixture(scope="class")
def web_driver(request):
    driver = webdriver.Chrome("C:/chromedriver.exe")
    request.cls.driver = driver
    yield
    web_driver.close()


@pytest.mark.usefixtures("web_driver")
class Base(unittest.TestCase):
    '''
    This fixture contains the set up and tear down code for each test.

    '''
    pass

and test class contains following code:

from core.web.Base import Base

class test(Base):

    def test_test(self):
        self.driver.get("http://google.com")

The test fixture is web_driver still getting error not found !

Answer

web_driver() is defined outside Base class scope, so it’s invisible to the usefixtures as it is part of test class scope. You could move it to conftest file, but IMHO a better solution is to move web_driver inside Base

@pytest.mark.usefixtures("web_driver")
class Base(unittest.TestCase):

    @pytest.fixture(scope="class")
    def web_driver(self, request):
        driver = webdriver.Chrome("C:/chromedriver.exe")
        request.cls.driver = driver
        yield
        driver.close()

As a side note, it should be driver.close(), not web_driver.close()
