python3支持在通过requests库调试django后台接口写测试用例

python测试用例库使用

unittest库可以支持单元测试用例编写和验证。

基本使用方法

运行文件可以将文件中的用例全部执行一遍

import unittest

class TestBasicFunc(unittest.TestCase):
    def test_basic_asert(self):
        self.assertEqual(1, 1)

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

运行结果如下图：

基本断言用法

基本断言用法如下：

import unittest
class TestBasicFunc(unittest.TestCase):
    def test_basic_asert(self):
        self.assertEqual(1, 1)
        self.assertNotEqual(1, 2)
        self.assertAlmostEqual(3.01, 3.02, places=1)
        self.assertNotAlmostEqual(3.1, 2.9, places=2)
        self.assertTrue(3>2)
        self.assertFalse(3<2)
        self.assertIs("Hello", str("Hello"))
        self.assertIn("s", "is a good")

python支持requests库发送网络请求

发送get请求，解析对应返回json文本

import requests

def try_request_get_test_case():
    url = "http://127.0.0.1:8000/index/"
    headers = {"Content-Type": "application/json"}
    response = requests.get(url, headers=headers)
    return_json = json.loads(response.text)
    print(return_json)
    return return_json

发送post请求

import requests

def try_request_post_test_case():
    url = "http://127.0.0.1:8000/index/"
    payload = {
        "postWoman" : "localTest"
    }
    headers = {"Content-Type": "application/json"}
    response = requests.post(url, json=payload, headers=headers)
    return_json = json.loads(response.text)
    print(return_json)
    return return_json

django支持解析json格式body

解析json格式的body，需要用.body，而不是get函数

from django.shortcuts import render
from django.shortcuts import HttpResponse
import json
# Create your views here.
def index(request):
    postWoman=""
    if request.method == "POST":
        print("index!")
        body_json = json.loads(request.body)
        postWoman = body_json["postWoman"]
        print(postWoman)
    data = {
        'name':"hhhh",

        'age':'15',
        'item':"test",
        "postWoman":postWoman
    }
    return HttpResponse(json.dumps(data));
