django客户端测试

此发布会签到系统是我跟着虫师的《Web接口开发与自动化测试》做的项目。此项目基于django框架，使用到了python、HTML语言并涉及到非常多的技术。

一、django.test.Client类

充当一个虚拟的网络浏览器，可以测试视图（view）与django的应用程序以编程方式交互。该类可做的事情如下：

• 模拟get和post请求，观察响应结果；
• 检查重定向链，再每一步检查URL和status code；
• 用一个包括特定值的模板context来测试一个request被django模板渲染。

D:\Python37\Scripts\guestProject>python manage.py shell

Python 3.7.5 (tags/v3.7.5:5c02a39a0b, Oct 15 2019, 00:11:34) [MSC v.1916 64 bit (AMD64)] on win32

Type "help", "copyright", "credits" or "license" for more information.

(InteractiveConsole)

>>> from django.test.utils import setup_test_environment

>>> setup_test_environment()

>>> from django.test import Client

>>> c = Client()

>>> response = c.get('/index/')

>>> response.status_code

200

二、举例

from django.test import TestCase
from sign.models import Event,Guest
from django.contrib.auth.models import User

# Create your tests here.

class IndexPageTest(TestCase):
    '''测试index登录首页'''

    def test_index_page_renders_index_template(self):
        '''测试index视图'''
        response = self.client.get('/index/')
        self.assertEqual(response.status_code,200)
        self.assertTemplateUsed(response,'index.html')

class LoginActionTest(TestCase):
    '''测试登录动作'''

    def setUp(self):
        User.objects.create_user('admin','admin@mail.com','admin123456')

    def test_add_admin(self):
        '''添加用户测试'''
        user = User.objects.get(username='admin')
        self.assertEqual(user.username,"admin")
        self.assertEqual(user.email,"admin@mail.com")

    def test_login_action_username_password_null(self):
        '''用户名密码为空'''
        test_data = {'username':'','password':''}
        respongse = self.client.post('/login_action/', data=test_data)
        self.assertEqual(respongse.status_code,200)
        self.assertIn(b"user or password error!",respongse.content)

    def test_login_action_username_password_error(self):
        '''用户名密码错误'''
        test_data = {'username':'abc','password':'123'}
        response = self.client.post('/login_action/', data=test_data)
        self.assertEqual(response.status_code,200)
        self.assertIn(b"user or password error!",response.content)

    def test_login_action_success(self):
        '''登录成功'''
        test_data = {'username': 'admin', 'password': 'admin123456'}
        response = self.client.post('/login_action/', data=test_data)
        self.assertEqual(response.status_code,302)

执行结果：
