　　前面已经写过一个封装定位了，但是可能在yaml中书写的时候过于繁琐，以及如果代码基础较差的同学，也没有办法进行编写测试用例。就重新进行封装一次定位

页面元素写入yaml

上一篇写的yaml可能有点杂乱，这次我们换个写法

把一个页面上元素编写上去，这里没有写验证码的操作了。

# appium.yaml

LoginPage:
  dec: 登录
  locators:
    -
      name: 用户名
      

type: id
      value: com.taobao.taobao:id/aliuser_login_mobile_et
    -
      name: 密码
      type: android
      value: resourceId("com.taobao.taobao:id/aliuser_register_sms_code_et")
    -
      name: 登录按钮
      type: className
      value: android.widget.Button

我们可以进行通过yaml读取，如果猜的没错的话，肯定是列表包含字典形式。

# read_yaml.py

import

 yaml
import os
class   GetYaml():
    def __init__(self,file_path):
        # 判断文件是否存在
        if os.path.exists(file_path):
            self.file_path = file_path
        else:
            print('没有找到%s文件路径'%file_path)
        self.data = self.read_yaml()
    def read_yaml(self):
         with open(self.file_path,'r',encoding='utf-8')as f:
            p = f.read()
            return p
    def get_data(self,key=None):
        result = yaml.load(self.data,Loader=yaml.FullLoader)
        if key == None:
            return result
        else:
            return result.get(key)

if __name__ == '__main__':
    read_yaml = GetYaml('E:/appium_python/config/appium.yaml')
    xx = read_yaml.get_data('LoginPage')
    print(xx['locators'])

[{'name': '用户名', 'type': 'id', 'value': 'com.taobao.taobao:id/aliuser_login_mobile_et'}, {'name': '密码', 'type': 'android', 'value': 'resourceId("com.taobao.taobao:id/aliuser_register_sms_code_et")'}, {'name': '登录按钮', 'type': 'className', 'value': 'android.widget.Button'}]

这里我们可以思考一个问题，上面元素以字典的形式存在的，那么我们可以不可以把请求定位方法的时候，直接把字典放进去，然后获取到元素坐标，定位方法，直接进行了。顺便把点击，输入等关键字一起封装进去？这样不就可以直接写了么？

封装定位方法

这里我们还安装以前的封装定位，不过这里传入的参数变成字典形式

# Base.py

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as ECfrom common.read_yaml import GetYaml
class BaseApp:
    def __init__(self, driver):
        self.driver = driver
    def find(self, locator):
        if not isinstance(locator, dict):
            print('定位参数locator传值不对，必须传入字典,如: {"name": "输入账号", "by": "id", "value": "xxx"}')

        if "name" in locator:
            print("正在操作元素名称\"%s\"" %locator['name']+",定位方法: %s-->%s"% (locator['type'], locator['value']))
        if locator["type"] == "id":
            value = locator["value"]
            element = WebDriverWait(self.driver, 10, 0.5).until(lambda x: x.find_element_by_id(value))
        elif locator["type"] == "android":
            value = locator["value"]
            element = WebDriverWait(self.driver, 10, 0.5).until(lambda x: x.find_element_by_android_uiautomator(value))
        elif locator["type"] == 'className':
            value = locator['value']
            element = WebDriverWait(self.driver, 10, 0.5).until(lambda x: x.find_element_by_class_name(value))
        elif locator["type"] == "text":
            value = "//*[@text='%s']" % locator["value"]
            _loc = ("xpath", value)
            element = WebDriverWait(self.driver, 10, 0.5).until(EC.presence_of_element_located(_loc))
        else:
            loc = (locator["type"], locator["value"])  # 元祖
            element = WebDriverWait(self.driver, 10, 0.5).until(EC.presence_of_element_located(loc))
        return element

    def get_element(self,path,key):
        '''读取元素'''
        yaml_data = GetYaml(path)
        local = yaml_data.get_data(key)
        return local

    def click(self, locator):
        '''点击元素'''
        el = self.find(locator)
        el.click()

    def send_text(self, locator, text):
        '''发送文本'''
        el = self.find(locator)
        el.send_keys(text)

提取页面元素

现在写代码都遵循的PO模型，我们把页面的元素也全部都提取出来，方便写用例的时候直接进行获取

# coding:utf-8
# login_page2.py

from common.Base import BaseApp
import os
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from common.appium_start import Android_device
path  =os.path.dirname(os.getcwd())
# 获取到yaml文件路径，
yaml_path = os.path.join(os.path.join(path,'config'),'appium.yaml')
class Login_element:
    def __init__(self,driver):
        self.driver = driver
        self.get_element = BaseApp(self.driver)
    def user_element(self):
        ''' 获取用户名元素'''
        element = self.get_element.get_element(yaml_path,'LoginPage')['locators'][0]
        return element

    def password_element(self):
        ''' 获取密码元素'''
        element = self.get_element.get_element(yaml_path,'LoginPage')['locators'][1]
        return element

    def login_boot(self):
        ''' 获取登录按钮元素'''
        element = self.get_element.get_element(yaml_path,'LoginPage')['locators'][2]
        return element

    def toast(self,message):
        '''获取toast信息'''
        tost_element = ("xpath","//*[contains(@text,"+message+")]")
        element = WebDriverWait(self.driver,10,0.1).until(EC.presence_of_element_located(tost_element)).text
        return element

编写用例

前面需要封装的都写好了，然后这里我们在unittest的情况下编写登录的用例

# case.py
from
 common.Base import BaseApp
from common.appium_start import Android_device,start
from pages.login_page2 import Login_element
import unittest
import threading
import time
class BaseDriver(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        cls.driver = Android_device()
        cls.app = BaseApp(cls.driver)
        cls.element = Login_element()
    def test_01(self):
        '''账号密码错误'''
        self.app.send_text(self.element.user_element(),'1111')
        self.app.send_text(self.element.password_element(),'2222')
        self.app.click(self.element.login_boot())
        element = self.element.toast('手机号')
        self.assertIn(element,'请输入正确的手机号')
    @classmethod
    def tearDownClass(cls):
        cls.driver.quit()
if __name__ == '__main__':
    # 启动 appium
    t1 = threading.Thread(target=start)
    t1.start()
    time.sleep(20)
    # 启动用例
    t2 = threading.Thread(target=unittest.main())
    print(t2)
    t2.start()
