python selenium multiple test cases

Question

I have the following code in python

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException
from unittestzero import Assert
from selenium.webdriver.support.ui import WebDriverWait
from selenium.common.exceptions import ElementNotVisibleException
import unittest, time, re

class HomePageTest(unittest.TestCase):
    expected_title="  some title here "
    def setUp(self):
        self.driver = webdriver.Firefox()
        self.driver.implicitly_wait(30)
        self.base_url = "https://somewebsite.com"
        self.verificationErrors = []

    def test_home_page(self):
        driver=self.driver
        driver.get(self.base_url)
        print "test some things here"




    def test_whatever(self):
        print "test some more things here"

    def tearDown(self):
        self.driver.quit()


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

My problem is after the function test_home_page, the firefox instance closes and opens again for the next test_whatever function. How can I do his so that all the test cases are executed from the same firefox instance.

Answer 1

Usually you want the browser to close between tests so that you start each test with a clean cache, localStorage, history database, etc. Closing the browser between tests does slow down the tests, but it saves in debug time because a test doesn't interact with the browser cache and history of a previous test.

Answer 2

Initialize the firefox driver in __init__:

class HomePageTest(unittest.TestCase):
    def __init__(self):
        self.driver = webdriver.Firefox()
        self.driver.implicitly_wait(30)
        self.base_url = "https://somewebsite.com"
        self.verificationErrors = []

    ...

    def tearDown(self):
        self.driver.quit()
