Open up functional_tests.py Change to same like this :

from selenium.webdriver.common.keys import Keys
import unittest

        inputbox.send_keys('Buy peacock feathers')

Run tests again :

Output Result

TIME TO GIT

Next , create template , run this command first

then Create directory in lists/templates/home.html and create home.html at lists/templates/home.html and in home.html has code

and change code in lists/views.py in same like this

RUN TESTS AGAIN

output result

" Django can't find the template "

and then fix INSTALLED_APPS area in superlists/settings.py and change to same like this

RUN TESTS AGAIN

output result

" self.assertTrue(response.content.endswith(b'</html>'))
AssertionError: False is not true "

Let's fix that [get pass] in lists/tests.py in method test_home_page_returns_correct_html

now RUN TESTS AGAIN

output result
