自动化测试模型

概念：

1、线性测试：单纯模拟用户完整的操作场景，每个脚本相对独立，且不产生依赖与调用。

2、模块化与类库：把重复的操作单独封装成公共模块，需要时进行调用。

3、数据驱动测试：参数化测试数据。

4、关键字驱动测试：把自动化操作封装成为“关键字”

模块化与参数化：

163邮箱登录与退出:save as: test_mail.py

from selenium import webdriver
from time import sleep

driver = webdriver.Chrome()
driver.get("https://mail.163.com/")
driver.implicitly_wait(10)

#登录
iframe = driver.find_element_by_css_selector("iframe")
driver.switch_to.frame(iframe)
driver.find_element_by_css_selector("[name = 'email']").send_keys("****")
driver.find_element_by_css_selector("[name = 'password']").send_keys("***")
driver.find_element_by_id("dologin").click()
driver.switch_to.default_content()

#退出
driver.find_element_by_id("_mail_icon_0_0").click()
driver.find_element_by_id("_mail_component_72_72").click()

模块化：save as :module.py

class Mail:
    def __init__(self,driver):
        self.driver = driver

    def login(self):
        """登录"""

        iframe = self.driver.find_element_by_css_selector("iframe")
        self.driver.switch_to.frame(iframe)
        self.driver.find_element_by_css_selector("[name = 'email']").send_keys("***")
        self.driver.find_element_by_css_selector("[name = 'password']").send_keys("***")
        self.driver.find_element_by_id("dologin").click()
        self.driver.switch_to.default_content()

    def logout(self):
        """退出"""
        self.driver.find_element_by_id("_mail_icon_0_0").click()
        self.driver.find_element_by_id("_mail_component_72_72").click()
    

修改test_mail.py文件调用Mail中的login() 、logout()

from selenium import webdriver
from time import sleep
from module import Mail

driver = webdriver.Chrome()
driver.get("https://mail.163.com/")
driver.implicitly_wait(10)

mail = Mail(driver)

mail.login()

mail.logout()

参数化（用户名密码）登录：修改module代码如下：

class Mail:
    def __init__(self,driver):
        self.driver = driver

    def login(self,username,password):
        """登录"""

        iframe = self.driver.find_element_by_css_selector("iframe")
        self.driver.switch_to.frame(iframe)
        self.driver.find_element_by_css_selector("[name = 'email']").clear()
        self.driver.find_element_by_css_selector("[name = 'email']").send_keys(username)
        self.driver.find_element_by_css_selector("[name = 'password']").clear()
        self.driver.find_element_by_css_selector("[name = 'password']").send_keys(password)
        self.driver.find_element_by_id("dologin").click()
        self.driver.switch_to.default_content()

不同数据调用Login（）：

from selenium import webdriver
from time import sleep
from module import Mail

driver = webdriver.Chrome()
driver.get("https://mail.163.com/")
driver.implicitly_wait(10)

mail = Mail(driver)

mail.login("error","error")
sleep(2)
mail.login("123","123")
