如何用一个Firefox实例，Selenium WebDriver和Python一起运行多个测试？

Question

我正在学习使用Selenium WebDriver和Python编写自动测试。我在WidgetArea类中有几个测试，我想在Firefox的一个实例中运行它们，我知道我需要指定setUp和tearDown作为@classmethod，但我不知道还应该为实现该目标而更改哪些内容？代码可以发现如下：

import unittest 
from selenium import webdriver 


class WidgetArea(unittest.TestCase): 

@classmethod 
def setUp(cls): 

    # create new firefox session 
    cls.driver = webdriver.Firefox() 
    cls.driver.implicitly_wait(30) 
    cls.driver.maximize_window() 
    # navigate to aplication page 
    cls.driver.get("http://demoqa.com/") 
    cls.driver.title 

def test_widget_area(self): 

    elements = self.driver.find_elements_by_xpath("//div[@id='secondary']/aside") 
    self.assertEqual(4, len(elements)) 

def test_widget_list(self): 

    elements = self.driver.find_elements_by_xpath("//ul[@id='menu-widget']/li") 
    self.assertEqual(7, len(elements)) 

def test_interaction(self): 

    elements = self.driver.find_elements_by_xpath("//ul[@id='menu-interactions']/li") 
    self.assertEqual(5, len(elements)) 

@classmethod 
def tearDown(cls): 
    cls.driver.quit() 

if __name__ == '__main__': 
    unittest.main

我不selenium使用unittests，所以只要你喜欢尽管unittests规则，我可以告诉在特定的框架的测试，你可以调整和更新：

from selenium import webdriver 

class WidgetArea(): 

    def setUp(self): 
    self.driver = webdriver.Firefox() 
    self.driver.implicitly_wait(30) 
    self.driver.maximize_window() 
    self.driver.get("http://demoqa.com/") 

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

    def widget_area(self): 
    elements = self.driver.find_elements_by_xpath("//div[@id='secondary']/aside") 
    try: 
     assert len(elements) == 4 
     print("Test pass") 
    except AssertionError: 
     print("Assertion failed") 

    def widget_list(self): 
    elements = self.driver.find_elements_by_xpath("//ul[@id='menu-widget']/li") 
    try: 
     assert len(elements) == 7 
     print("Test pass") 
    except AssertionError: 
     print("Assertion failed") 

    def interaction(self): 
    elements = self.driver.find_elements_by_xpath("//ul[@id='menu-interactions']/li") 
    try: 
     assert len(elements) == 5 
     print("Test pass") 
    except AssertionError: 
     print("Assertion failed") 

    def main(self): 
    self.setUp() 
    self.widget_area() 
    self.widget_list() 
    self.interaction() 
    self.tearDown() 


if __name__ == '__main__': 
    new = WidgetArea() 
    new.main()
