Read JSON configuration file to realize data-driven testing

json File format ：

There are three groups of data in the file , It also corresponds to three test cases ： Registered successfully 、 The user name already exists 、 Message already exists .

{
    
  "test1- Registered successfully ": {
    
    "username": "test",
    "password": "123456",
    "email": "[email protected]",
    "phone": "13425335433",
    "question": " My favorite pet is ？",
    "answer": "cat",
    "exceptionresult": " Registered successfully "
  },
  "test2- The user name already exists ": {
    
    "username": "test",
    "password": "123456",
    "email": "[email protected]",
    "phone": "13425335433",
    "question": " My favorite pet is ？",
    "answer": "cat",
    "exceptionresult": " The user name already exists "
  },
  "test3- Message already exists ": {
    
    "username": "test1",
    "password": "123456",
    "email": "[email protected]",
    "phone": "13425335433",
    "question": " My favorite pet is ？",
    "answer": "cat",
    "exceptionresult": " The message already exists "
  }
}

Read in the test case json file , Drive test execution ：

① Import ddt Module package ：import ddt
② Use @ddt.ddt decorator
③ Use @ddt.file_data(“json File path ”) Modify the test case method .
④ The name of the parameter of the test case method needs to be the same as json Medium key Consistent values , Otherwise, the parameter value cannot be passed correctly .
The framework used by the current test case class is unittest frame .

# coding: utf-8
import unittest
import ddt
import os
from interface.registerInterface import RegisterInterface


@ddt.ddt
class RegisterTest(unittest.TestCase):
    ''' register '''
    @classmethod
    def setUpClass(cls) -> None:
        cls.url = 'http://localhost:8080/jwshoplogin/user/register.do'
        cls.registerInterface = RegisterInterface(cls.url)
        pass

    def setUp(self) -> None:
        pass

    def tearDown(self) -> None:
        # print(" Use case execution passes .")
        pass

    @classmethod
    def tearDownClass(cls) -> None:
        pass

    @ddt.file_data(os.path.join(os.path.dirname(os.path.dirname(__file__)), 'jsondata') + r'\registerTest.json')
    def test(self, username, password, email, phone, question, answer, exceptionresult):
        userinfo = {
    
            "username": username,
            "password": password,
            "email": email,
            "phone": phone,
            "question": question,
            "answer": answer
        }
        self.registerInterface.aw_send_register_request(userinfo)
        result = self.registerInterface.aw_check_result(exceptionresult)
        self.assertEqual(result, True, " Test to fail , The expected result is {0}, For the actual {1}".format(exceptionresult, result))
        pass


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

Referenced in the above class RegisterInterface class ：

# coding: utf-8
import requests

'''1、username：test2 2、password:123456 3、email:[email protected] 4、phone：[phone]、question： My favorite pet is ？ 6、answer：cat '''


class RegisterInterface(object):
    def __init__(self, url):
        self.url = url
        self.response = None
        pass

    def aw_send_register_request(self, userinfo):
        self.response = requests.post(self.url, data=userinfo)
        # print(self.response.text)
        pass

    def aw_check_result(self, exception):
        if exception in self.response.text:
            return True
        else:
            if self.response.json()['data']:
                return self.response.json()['data']
            else:
                return self.response.json()['msg']

Execute test case ：

Although in RegisterTest There is only one written in the test case test Method , But the number of use cases executed is 3 individual , This is because json The data file contains 3 Group data , This is it. ddt The charm of data-driven testing , It greatly improves the reuse rate of code , And if you need to add test cases for the same request process , Only need json Add a group of test data to the file , No need to change the code .

Add a set of data to json In file ：

{
    
  "test1- Registered successfully ": {
    
    "username": "test",
    "password": "123456",
    "email": "[email protected]",
    "phone": "13425335433",
    "question": " My favorite pet is ？",
    "answer": "cat",
    "exceptionresult": " Registered successfully "
  },
  "test2- The user name already exists ": {
    
    "username": "test",
    "password": "123456",
    "email": "[email protected]",
    "phone": "13425335433",
    "question": " My favorite pet is ？",
    "answer": "cat",
    "exceptionresult": " The user name already exists "
  },
  "test3- Message already exists ": {
    
    "username": "test1",
    "password": "123456",
    "email": "[email protected]",
    "phone": "13425335433",
    "question": " My favorite pet is ？",
    "answer": "cat",
    "exceptionresult": " The message already exists "
  },
  "test4- Registered successfully ": {
    
    "username": "test1",
    "password": "123456",
    "email": "[email protected]",
    "phone": "13425335411",
    "question": " My favorite pet is ？",
    "answer": "cat",
    "exceptionresult": " Registered successfully "
  }
}

Execution results ：
