Ddt+yaml implementation of data driven mechanism based on unittest

---

1.data.txt

 account number , password 

2.demo.yaml

-
  name: xuzhu
  age: '14'
  sexual: male
  hobby:
    -  Locomotive 
    -  Thai Boxing 
    -  Boxing 
  address:
     Changsha : xxx
#  city in Hunan : xxx

3.login.yaml

-
#  Anchor point 
# common: &defaults
  common:
    url: http://39.98.138.157/shopxo/index.php?s=/index/user/logininfo.html

    accounts:
      by: name
      value: accounts


    password:
      by: name
      value: pwd


    button:
      by: xpath
      value: //button[text()=" Sign in "]

    assert_text:
      expected:  sign out 
      by: link text
      value:  sign out 

    sleep: 5

# common:
# <<: *defaults
# xuzhu: sssss

# username: xuzhu666
# pwd: xxx

4.search.yaml

-
  url: http://39.98.138.157/shopxo/index.php

  input:
    by: id
    value: search-input
    txt:  mobile phone 

  click:
    by: id
    value: ai-topsearch

  sleep: 5

5. Read yaml file

import yaml

file = open('./data/login.yaml','r',encoding = 'utf-8')
values = yaml.load(stream = file,Loader = yaml.FullLoader)
for value in values:
    print(value)

6.DDT Use

''' Unittest Automatic test implementation under   A complete process , Different small processes are divided into different use cases to manage . This is easy to maintain  DDT Use ( Don't pass all the data directly @data Decorator for transmission ):  Use through decorator form  1. @data Data driven implementation of decorator : Import relatively simple or fixed data content  [email protected] Decorator : take data Disassemble the data twice , It is convenient to meet the situation that multiple parameters are passed in during the execution of a single use case  [email protected]_data() Decorator , obtain yaml File content in format  4. stay setup and teardown in , Will not import ddt Any decorator to do data-driven   Include setupclass\teardownclass @data([' Xiaoyou should work hard ！',' Yunsha Liying should learn ！'])  What you get after disassembling is a list, If you want to list Split twice , You need to add @unpack Decorator  unpack:[' Xiaoyou should work hard ！',' Yunsha Liying should learn ！'] The second is based on , To break up   get ' Xiaoyou should work hard ！',' Yunsha Liying should learn ！' Two figures  '''
import unittest

from ddt import ddt, data, unpack, file_data

from class24.web_keys import Keys

1. Get file data content

def read_file():
    values = list()
    file = open('./data/data.txt', 'r', encoding='utf-8')
    for line in file.readlines():
        values.append(line)
    return values

2. call ddt Data driven

#  Must be in class Add ddt The decorator 
@ddt

    #  Back and forth 
    @classmethod
    def setUpClass(cls) -> None:

    # self.key.input('name','pwd','xxx')
    # self.key.click('xpath','//button[text()=" Sign in "]')
    # self.assertEqual() # Be similar to  assert a == b,msg
    # self.assertTrue(self.key.assert_text('link text',' sign out ',' sign out 1'),msg = ' Assertion failed ')
    # self.assertEqual(' sign out 1',self.key.get_text('link text',' sign out '),msg = ' Assertion failed ')
    # self.key.sleep(5)
    # key.quit()


    # @file_data('./data/login.yaml')
    # def test_01_login(self,**kwargs):

    # self.assertEqual(kwargs['assert_text']['expected'],self.key.get_text(kwargs['assert_text']['by'],kwargs['assert_text']['value']),msg=' Assertion failed ')
    # self.key.sleep(kwargs['sleep'])

    @file_data('./data/login.yaml')
    def test_01_login(self, **kwargs):
        data = kwargs['common']
        self.key.open(data['url'])

                         self.key.get_text(data['assert_text']['by'], data['assert_text']['value']), msg=' Assertion failed ')
        self.key.sleep(data['sleep'])

    # def test_02_search(self):
    # key = Keys('Chrome')
    # self.key.open('http://39.98.138.157/shopxo/index.php')
    # self.key.input('id','search-input',' mobile phone ')
    # self.key.click('id','ai-topsearch')
    # self.key.sleep(5)
    # key.quit()

    # @file_data('./data/search.yaml')
    # def test_02_search(self,**kwargs):
    # self.key.open(kwargs['url'])
    # self.key.input(**kwargs['input'])
