UnitTest测试固件、参数parameterized

 

1、UnitTest的使用：

   （1）、setUp（）、teardown（）每个测试用例都执行一次

import unittest
from selenium import webdriver

class TestUi(unittest.TestCase):
    def setUp(self) -> None:
        print('开始执行')

    def  tearDown(self) -> None:
        print('执行结束')

    def test_login_001(self):
        pass

    def test_login_002(self):
        pass

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

　　例：

from selenium import  webdriver
import  unittest
import time as t

class TestSina(unittest.TestCase):
    @classmethod
    def setUpClass(cls) -> None:
        '''初始化'''
        cls.driver=webdriver.Chrome()
        cls.driver.maximize_window()
        cls.driver.get('https://mail.sina.com.cn/')
        cls.driver.implicitly_wait(30)

    @classmethod
    def tearDownClass(cls) -> None:
        cls.driver.quit()

    def test_sina_001(self):
        isLogin=self.driver.find_element_by_id('store1')
        #验证
        self.assertEqual(isLogin.is_selected(),True)

    def test_sina_002(self):
        self.driver.find_element_by_link_text('登录').click()
        t.sleep(3)
        #注意定位，容易出错
        divText=self.driver.find_element_by_xpath('/html/body/div[3]/div/div[2]/div/div/div[4]/div[1]/div[1]/div[1]/span[1]')
        self.assertEqual(divText.text,'请输入邮箱名')

    def test_sina_003(self):
        self.driver.find_element_by_id('freename').send_keys('lyl123@sina.com')
        self.driver.find_element_by_link_text('登录').click()
        t.sleep(3)
        divText=self.driver.find_element_by_xpath('/html/body/div[3]/div/div[2]/div/div/div[4]/div[1]/div[1]/div[1]/span[2]')
        self.assertEqual(divText.text=='请输入密码',True)

    def test_sina_004(self):
            # 先获取注册页面的窗口
            nowHander = self.driver.current_window_handle
            # 点击注册页面，跳转到注册的页面
            self.driver.find_element_by_link_text('注册').click()
            # 获取所有窗口
            allHanders = self.driver.window_handles
            # 对所有的窗口进行循环处理
            for handler in allHanders:
                # 判断当前窗口（如果不是当前窗口）
                if nowHander != handler:
                    # 获取当前窗口
                    self.driver.switch_to.window(handler)
                    # 断言
                    self.assertEqual(self.driver.current_url, 'https://mail.sina.com.cn/register/regmail.php')
                    self.driver.close()

if __name__=='__main__':
    unittest.main(verbosity=2)

　（2）、setUpClass（）、teardownClass（）只执行一次

import unittest
from selenium import webdriver

class TestUi(unittest.TestCase):
    @classmethod
    def setUpClass(cls) -> None:
        print('开始执行')

    @classmethod
    def  tearDownClass(cls) -> None:
        print('执行结束')

    def test_login_001(self):
        pass

    def test_login_002(self):
        pass

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

　　例：

from selenium import  webdriver
import  unittest
import time as t

class TestSina(unittest.TestCase):
    @classmethod
    def setUpClass(cls) -> None:
        '''初始化'''
        cls.driver=webdriver.Chrome()
        cls.driver.maximize_window()
        cls.driver.get('https://mail.sina.com.cn/')
        cls.driver.implicitly_wait(30)

    @classmethod
    def tearDownClass(cls) -> None:
        cls.driver.quit()

    def test_sina_001(self):
        isLogin=self.driver.find_element_by_id('store1')
        #验证
        self.assertEqual(isLogin.is_selected(),True)

    def test_sina_002(self):
        self.driver.find_element_by_link_text('登录').click()
        t.sleep(3)
        #注意定位，容易出错
        divText=self.driver.find_element_by_xpath('/html/body/div[3]/div/div[2]/div/div/div[4]/div[1]/div[1]/div[1]/span[1]')
        self.assertEqual(divText.text,'请输入邮箱名')

    def test_sina_003(self):
        #先获取注册页面的窗口
        nowHander=self.driver.current_window_handle
        #点击注册页面，跳转到注册的页面
        self.driver.find_element_by_link_text('注册').click()
        #获取所有窗口
        allHanders=self.driver.window_handles
        #对所有的窗口进行循环处理
        for handler in allHanders:
            #判断当前窗口（如果不是当前窗口）
            if nowHander!= handler:
                #获取当前窗口
                self.driver.switch_to.window(handler)
                #断言
                self.assertEqual(self.driver.current_url,'https://mail.sina.com.cn/register/regmail.php')
                self.driver.close()
                #关闭注册页面后在返回到登录页面（才能继续执行下一步）
                self.driver.switch_to.window(nowHander)

    def test_sina_004(self):
        self.driver.find_element_by_id('freename').send_keys('lyl123@sina.com')
        self.driver.find_element_by_link_text('登录').click()
        t.sleep(3)
        divText=self.driver.find_element_by_xpath('/html/body/div[3]/div/div[2]/div/div/div[4]/div[1]/div[1]/div[1]/span[2]')
        self.assertEqual(divText.text=='请输入密码',True)

if __name__=='__main__':
    unittest.main(verbosity=2)

2、安装parameterized（参数化）

   在电脑搜索栏中输入cmd（打开命令提示符），在管理员权限下--->输入pip3 install parameterized（自动安装）

 

3、param使用

import unittest
from parameterized import  parameterized,param

def add(a,b):
    return a+b

class AddTest(unittest.TestCase):
    def setUp(self) -> None:
        pass

    def tearDown(self) -> None:
        pass

    @parameterized.expand([
        param(1,1,2),
        param(2,2,4),
        param(1.0,2.0,3.0),
        param('ni',' hao','ni hao'),
    ])
    def test_add(self,a,b,result):
        self.assertEqual(add(a,b),result)

if __name__ == '__main__':
    unittest.main(verbosity=2)
