Answer 1

I would change the structure of you code to something like this:
And make sure driver is actually installing (you can use hard coded path once to see the problem)

@pytest.fixture(scope="class")
def driver(request):
    driver = webdriver.Chrome(ChromeDriverManager().install())
    driver.get("https://itera-qa.azurewebsites.net/Login")
    driver.maximize_window()
    yield driver
    driver.quit()

@pytest.fixture(scope="class")
def setup(request, driver):
    # put your wait here too
    request.cls.driver = driver

Answer 2

ttl = TestTomsLogin()
ttl.test_login()

The Issue got resolved by removing the above two lines. It should not be used when using pytest methods.
