Getting fixture not found in pytest
14,592
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()

I am getting following error while running pytest using following code im unable to figure out whats wrong please find below code snippets.
Console ouput :

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 !

user1323a about 5 yearsSolution worked but why cant we use outside the class it in same file it ?

Guy about 5 years@user1323a Updated my answer.

user1323a about 5 yearswhen Im running tests using this fixture when extending base class in two classes and trying to run test im getting error :Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it' but when running single class it runs fine is it a base class issue ?
-
Guy about 5 years@user1323a You run the tests in parallel? If you do it's expected, you need to use some parallelism mechanize (like Selenium Grid for example)
-
user1323a about 5 yearsissue gets resolved when i comment out driver.close line and it runs. I think problem is it driver gets closed and then the call is made to driver but how can i achive this without commenting out the driver.close becouse it uses same driver for all the tests how can i open browser for every test i tried changing scope
-
Guy about 5 years@user1323a I couldn't reproduce. Open a new question with the code of the base class and the tests you are trying to run, it's hard to solve this in the comments.
