Python interface test unittest usage details

unittest Framework analysis

unittest yes python The unit test framework of ,unittest Unit testing provides the ability to create test cases , Test suite and batch execution scheme , unittest In the installation pyhton I'll bring it myself , direct import unittest You can use .

open pycharm, introduce unittest package ,requests package

Then call unittest

class forTestTest(unittest.TestCase):  # call unittest

Use unittest Medium setUp Method , This unittest We can write the preconditions of login in this, and we need to get cookie perhaps token And so on

class forTestTest(unittest.TestCase):  # call unittest
    def setUp(self) -> None:             # precondition 
        # Login interface 
        re = requests.post(url='http://localhost:8888/login',data={'name': 'xiaohong', 'pwd': '456'})# Send interface request 
        print(re.text)# Print interface information 
        test = re.json()['data']['test'][0]['name']# Get the in the interface name value 
        print(test)# Print name value 
        global token# Set a global variable 
        token = re.json()['data']['token']# Assign values to global variables , The value is the response of the interface token Value

After adding a value condition , After the use case is executed, execute

def tearDown(self) -> None:          #  Postcondition 
    print(" end of execution ")# Print to mark the end of case execution

Write the specific interface to be executed , Write a query interface here , The login returned by calling the precondition token This value , Query interface access
!

def test_01(self):
    # Query interface 
    res = requests.post('http://127.0.0.1:8888/user', data={'token': token})# Request query interface , Carry the login interface token value 
    a = res.text
    print(a)# Print the results

If you don't want to write interface code here, you can use domestic interface testing tools apipost Directly generate

Run it and show you the results

Complete code

import unittest
import requests

class forTestTest(unittest.TestCase):  # call unittest
    def setUp(self) -> None:             # precondition 
        # Login interface 
        re = requests.post(url='http://localhost:8888/login',data={'name': 'xiaohong', 'pwd': '456'})# Send interface request 
        print(re.text)# Print interface information 
        test = re.json()['data']['test'][0]['name']# Get the in the interface name value 
        print(test)# Print name value 
        global token# Set a global variable 
        token = re.json()['data']['token']# Assign values to global variables , The value is the response of the interface token Value 


    def tearDown(self) -> None:          #  Postcondition 
        print(" end of execution ")# Print to mark the end of case execution 



    def test_01(self):
        # Query interface 
        res = requests.post('http://127.0.0.1:8888/user', data={'token': token})# Request query interface , Carry the login interface token value 
        a = res.text
        print(a)# Print the results 

if __name__ == '__main__':
