stay UI In the automated testing of , We need to separate the data used in the test into files , If it is simply written in our test module , Not a good design , So no matter what type of automated testing , It is necessary to separate the data . Of course, it is separated into specific documents , There are many forms of documents , The main point here is JSON Documents and YAML The documents are in UI Application in automated testing .

One 、JSON file

JSON Library is mainly used in serialization and deserialization , Especially in API In the automated testing of , Serialization and deserialization are the systems of technology stacks that must be mastered in the knowledge system . Of course, we can also deal with serialization and deserialization of files , Serialization of files can be simply understood as writing third-party data into files , Use JSON The method in the library is dump() Method , Then the anti serialization of files can be understood as reading data from files , Used JSON In the library load() Methods , The following is mainly for UI Automate the separation of test data , The specific code is ：

import unittest
from parameterized import  parameterized,param
from selenium  import  webdriver
import  time as t

#parameterized Is a parameterized Library 

class AddTest(unittest.TestCase):

    def setUp(self) -> None:
        self.driver=webdriver.Chrome()
        self.driver.maximize_window()
        self.driver.implicitly_wait(30)
        self.driver.get('https://mail.sina.com.cn/#')

    def tearDown(self) -> None:
        self.driver.quit()


    @parameterized.expand([
        param('','',' Please enter the email name '),
        param('srtSA','saert',' The email name you entered is not in the correct format '),
        param('[email protected]','asdfrty',' Wrong login or password ')
    ])
    def test_sina_email(self,username,password,result):
        t.sleep(2)
        self.driver.find_element_by_id('freename').send_keys(username)
        t.sleep(2)
        self.driver.find_element_by_id('freepassword').send_keys(password)
        t.sleep(2)
        self.driver.find_element_by_link_text(' Sign in ').click()
        t.sleep(3)
        div=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]')
        assert div.text==result

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

You can see in the above file , We can separate the test data into JSON In file , The separated data is ：

{
  "data":
  [
    {"username": "","password": "","text": " Please enter the email name "},
    {"username": "srtSA","password": "saert","text": " The email name you entered is not in the correct format "},
    {"username": "[email protected]","password": "asdfrty","text": " Wrong login or password "}
  ]
}

The improved test script is ：

import unittest
from parameterized import  parameterized,param
from selenium  import  webdriver
import  time as t
import  json

def readJson():
   return json.load(open('sina.json'))['data']

class AddTest(unittest.TestCase):

   def setUp(self) -> None:
      self.driver=webdriver.Chrome()
      self.driver.maximize_window()
      self.driver.implicitly_wait(30)
      self.driver.get('https://mail.sina.com.cn/#')

   def tearDown(self) -> None:
      self.driver.quit()


   @parameterized.expand([
      param(readJson()[0]['username'],readJson()[0]['password'],readJson()[0]['text']),
      param(readJson()[1]['username'],readJson()[1]['password'],readJson()[1]['text']),
      param(readJson()[2]['username'],readJson()[2]['password'],readJson()[2]['text'])
   ])
   def test_sina_email(self,username,password,result):
      t.sleep(2)
      self.driver.find_element_by_id('freename').send_keys(username)
      t.sleep(2)
      self.driver.find_element_by_id('freepassword').send_keys(password)
      t.sleep(2)
      self.driver.find_element_by_link_text(' Sign in ').click()
      t.sleep(3)
      div=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]')
      assert div.text==result


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

Two 、YAML file

Let's demonstrate how to store the test data in YAML In the document , The contents of the separated file are ：

username: ""
password: ""
text: " Please enter the email name "

---
username: "srtSA"
password: "saert"
text: " The email name you entered is not in the correct format "

---
username: "[email protected]"
password: "asdfrty"
text: " Wrong login or password "

The improved test script is ：

import unittest
from parameterized import  parameterized,param
from selenium  import  webdriver
import  time as t
import  json
import yaml

def readJson():
   return json.load(open('sina.json'))['data']


def readYaml():
   with open('sina.yaml') as f:
      return list(yaml.unsafe_load_all(f))

class AddTest(unittest.TestCase):

   def setUp(self) -> None:
      self.driver=webdriver.Chrome()
      self.driver.maximize_window()
      self.driver.implicitly_wait(30)
      self.driver.get('https://mail.sina.com.cn/#')

   def tearDown(self) -> None:
      self.driver.quit()


   @parameterized.expand([
      param(readYaml()[0]['username'],readYaml()[0]['password'],readYaml()[0]['text']),
      param(readYaml()[1]['username'],readYaml()[1]['password'],readYaml()[1]['text']),
      param(readYaml()[2]['username'],readYaml()[2]['password'],readYaml()[2]['text'])
   ])
   def test_sina_email(self,username,password,result):
      t.sleep(2)
      self.driver.find_element_by_id('freename').send_keys(username)
      t.sleep(2)
      self.driver.find_element_by_id('freepassword').send_keys(password)
      t.sleep(2)
      self.driver.find_element_by_link_text(' Sign in ').click()
      t.sleep(3)
      div=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]')
      assert div.text==result


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

Above , A detailed demonstration of the UI In the automated testing of , We can separate the test data used into JSON Document and YAML The file of , This achieves the separation of data , The purpose is to make the test simpler and more efficient .
