Rum multiple test cases using python selenium webdriver on same web browser session

Question

I have following code here:

import unittest
import time
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.common.exceptions import NoSuchElementException
from selenium.common.exceptions import NoAlertPresentException
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException

class MyTest1(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        cls.driver = webdriver.Firefox()
        driver = cls.driver
        driver.get("https://somewebsite.com")
        print "login the website"

    def test_UI_login(self):
        driver = self.driver
        print "test some things here"

    def test_duplicate_client(self):
        driver = self.driver
        print "test some things here"


    def tearDown(cls):
        cls.driver.close()


if __name__ == '__main__':
    unittest.main()

Problem I am facing is , After first function test_UI_login, the firefox instance closes. How can I execute multiple test cases from the same Firefox instance in unittest using selenium.

Perhaps it would help if you also annotate tearDown with @classmethod? — Frank

It didn't work out if we annotate tearDown with @classmethod — Manisha Verma

As stated in this SO-answer

you must initialize the driver in __init__ .

I tried as you suggested. But,I am getting below error, typeerror __init__() takes 1 positional argument but 2 were given class MyTest1(unittest.TestCase): def __init__(self): self.driver = webdriver.Firefox() driver = self.driver

You must declare __init__(cls, tests) Sorry for the misunderstanding, it's been a while since I used it. It looks like selenium adds an additional parameter in the latest versions.

Tried the method as suggested you(def __init__(cls, tests)), noticed below error 'MyTest1' object has no attribute '_testMethodName'

Oh, sorry. Forgot to mention that you have to implicitly call the superclasses init if you overwrite it. So adding ` unittest.TestCase.__init__(cls, tests)` as the first line in your init should work (At least it does for me) :-).

Assign the webdriver in __init__(), but don't forget to call super.__init__() to not break the tests mechanism:

    def __init__(self, *args):
        super().__init__(*args)
        self.driver = webdriver.Firefox()
