python - I am using unittest.TestCase if i have more than 1 test case it will not run. Only 1 test case runs -

i automating our website. using python, webdriver, unittest.testcase.

i had 1 test method defined in login page class test valid user log in. works fine.

now adding 2nd test method called test_login_invalid_user test invalid user log in. browsing log in page start see if 2nd test method gets called when run test.

when run code following error:

traceback (most recent call last): file "c:\users\riaz.ladhani\pycharmprojects\selenium webdriver\clearcore  \loginpage_testcase.py", line 40, in test_login_invalid_user login_page = page.login(self.driver) attributeerror: 'module' object has no attribute 'login' 

can not have more 1 test method in unit test? doing wrong way?

my unit test class code snippet follows:

import unittest selenium import webdriver import page import time  class loginpage_testcase(unittest.testcase):     def setup(self):         self.driver = webdriver.ie("c:\qa\automation\python_projects\selenium  webdriver\iedriverserver_win32_2.45.0\iedriverserver.exe")         self.driver.get("http://riaz-pc.company.local:8080/clearcore")      def test_login_valid_user(self):         login_page = page.loginpage(self.driver)         login_page.userlogin_valid()         login_page.isadministration_present()         assert login_page.isadministration_present(), "administration not found"         if login_page.isadministration_present() == "true":             print "test login valid user passed"         else:             print "test login valid user failed"      def test_login_invalid_user(self):         print "test_login_invalid_user"         login_page = page.login(self.driver)      def teardown(self):         self.driver.close()  if __name__ == "__main__":     unittest.main() 

from understand, meant define new loginpage page object instance instead:

def test_login_invalid_user(self):     print "test_login_invalid_user"     login_page = page.loginpage(self.driver) 

if case, avoid violating "dry" principle , improve readability, instantiate loginpage in setup():

class loginpage_testcase(unittest.testcase):     def setup(self):         self.driver = webdriver.ie("c:\qa\automation\python_projects\selenium  webdriver\iedriverserver_win32_2.45.0\iedriverserver.exe")         self.driver.get("http://riaz-pc.company.local:8080/clearcore")          self.login_page = page.loginpage(self.driver)      def test_login_valid_user(self):         self.login_page.userlogin_valid()         self.login_page.isadministration_present()         assert self.login_page.isadministration_present(), "administration not found"         if self.login_page.isadministration_present() == "true":             print "test login valid user passed"         else:             print "test login valid user failed"      def test_login_invalid_user(self):         print "test_login_invalid_user"         # use self.login_page here
