Question

在下面的代码中，我无法运行第二个测试功能 def testclick（self）

import unittest
from selenium import webdriver
from time import sleep

class LoginMaharaOrgLogin(unittest.TestCase):
    @classmethod
    def setUpClass(inst):
        inst.driver = webdriver.Chrome()
        #inst.driver.maximize_window()
        inst.driver.get("https://demo.mahara.org/")


    def testlogin(self):
        driver = self.driver
        self.assertEqual("Home - Mahara Demo", driver.title)
        driver.find_element_by_xpath("//input[@id='login_login_username']").send_keys("student")
        driver.find_element_by_xpath("//input[@id='login_login_password']").send_keys("MaharaDemo")
        driver.find_element_by_xpath("//input[@id='login_submit']").click()
        driver.find_element_by_xpath("//span[@class='icon icon-chevron-down collapsed']").click()
        sleep(3)


    def testclick(self):
        self.driver.find_element_by_xpath("//span[text()='Logout']").click()



    @classmethod
    def tearDownClass(inst):
        inst.driver.close()

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

当我运行上面的代码时，我得到错误：

Finding files... done.
Importing test modules ... done.

Ran 2 tests in 18.020s

FAILED (errors=1)

但如果我包括这个：

self.driver.find_element_by_xpath("//span[text()='Logout']").click()

def testlogin(self)中的

语句有效

Answer 1

你可以尝试：

def testclick(self):
    driver.find_element_by_xpath("//span[text()='Logout']").click()

Answer 2

unittest framework executes test functions based on the name of the function and not in the order that is placed. in your case its executing testclick() first & it's not finding the element. so use test1_login(self): and test2_logout(self): as function name it will work.
