12、Django_test

1、概述

不一样的项目类型里面的单元测试基本不一样

2、测试项目分析

一、models.py页面：模型页面

1.一、tests.py文件里面写入case

from django.test import TestCase
from sign.models import Event,Guest   #导入引用的模块
# Create your tests here.

class ModelsTest(TestCase): #建立测试类，继承Django下面的TestCase方法

    def test_event(self):  #建立测试类
        Event.objects.create(id=1, name="oneplus 3 event", status=True, limit=2000,
                             address='shenzhen', start_time='2016-08-31 02:18:22')   #数据初始化，建立一条发布会数据来提供后面进行查找
        results =  Event.objects.all()  #调用，并非真正的去查找相对应的数据，须要在前面先建立发布会的字段才能够查找到
        print(results)

 1.二、终端进入到相对应的目录，而且使用Test方法运行脚本

 monkey@MacBook-Pro-7  /usr/local/lib/python3.6/site-packages/guest  python3 manage.py test
Creating test database for alias 'default'...
/usr/local/lib/python3.6/site-packages/pymysql/cursors.py:161: Warning: 'NO_ZERO_DATE', 'NO_ZERO_IN_DATE' and 'ERROR_FOR_DIVISION_BY_ZERO' sql modes should be used with strict mode. They will be merged with strict mode in a future release.
  result = self._query(query)

  result = self._query(query)

  result = self._query(query)

 1.三、运行原理

跟上面的unittest原理同样

先找代码中有没有继承Django中Test下面的TestCase类

再查找定义的方法中是否有test开头的方法，若是有的话就执行

case运行的前后顺序为：经过ASCII码的排序进行排序运行

初始化的数据并不会到数据库里面，只是提供测试操做

1.四、case的断言操做

tests.py文件

from django.test import TestCase
from sign.models import Event,Guest   #导入引用的模块
# Create your tests here.

class ModelsTest(TestCase): #建立测试类，继承Django下面的TestCase方法

    def test_event(self):  #建立测试类
        Event.objects.create(id=1, name="test1", status=True, limit=2000,
                             address='shenzhen', start_time='2016-08-31 02:18:22')   #初始化测试数据，供下面查询使用，这条数据并不会直接到数据库里面，只是提供测试查询须要
        results =  Event.objects.get(name = 'test1')  #查询相对应的方式不会真正的去数据库查询数据，须要经过上面的方法建立数据
        print(results.limit)
        print(results.address)
        self.assertEqual(results.limit,2000)  #断言查询出来的数据是否limit =  2000
        self.assertEqual(results.address,'shenzhen')   #断言查询出来的数据 是否address = 'shenzhen'

终端运行结果

 monkey@MacBook-Pro-7  /usr/local/lib/python3.6/site-packages/guest  python3 manage.py test

 1.五、使用setUp()、tearDown()

tests.py文件

from django.test import TestCase
from sign.models import Event,Guest   #导入引用的模块
# Create your tests here.

class ModelsTest(TestCase): #建立测试类，继承Django下面的TestCase方法

    def setUp(self):
        #初始化发布会数据
        Event.objects.create(id=1, name="test1", status=True, limit=2000,
                             address='shenzhen', start_time='2016-08-31 02:18:22')
        #初始化嘉宾表数据
        Guest.objects.create(id=2, event_id=1, realname='alen',
                             phone='13711001101', email='alen@mail.com', sign=False)

    #发布会的case
    def test_event(self):
        results =Event.objects.get(name = 'test1')
        print(results.limit)
        print(results.address)
        self.assertEqual(results.limit,2000)
        self.assertEqual(results.address,'shenzhen')

    #嘉宾表的case
    def test_guest(self):
        results =Guest.objects.get(realname= 'alen')
        self.assertEqual(results.phone,'13711001101')
        self.assertEqual(results.email,'alen@mail.com')

 终端页面

 monkey@MacBook-Pro-7  /usr/local/lib/python3.6/site-packages/guest  python3 manage.py test

  result = self._query(query)

二、views.py页面：视图页面

2.一、初始化测试环境

终端进入shell模式

导入Client类，模拟post、get请求，加入路径，若是返回码为200则表示成功，创建了测试环境

monkey@MacBook-Pro-7  /usr/local/lib/python3.6/site-packages/guest  python3 manage.py shell
Python 3.6.3 (default, Oct 17 2017, 00:27:06)
[GCC 4.2.1 Compatible Apple LLVM 8.1.0 (clang-802.0.42)] on darwin

>>> from django.test import Client   #导入Client类
>>> c = Client()
>>> response = c.get("/index/")    #相似于模拟界面自动化测试的方法，加入相对应的跳转后缀，模拟index页面登陆效果
>>> response.status_code   #获取返回码
200

 2.二、测试case编写

index页面登陆case编写

class TestIndex(TestCase):

    def test_idex(self):
        respose = self.client.get('/index/')
        print(respose.status_code)

 运行结果

 monkey@MacBook-Pro-7  /usr/local/lib/python3.6/site-packages/guest  python3 manage.py test
Creating test database for alias 'default'...
/usr/local/lib/python3.6/site-packages/pymysql/cursors.py:161: Warning: 'NO_ZERO_DATE', 'NO_ZERO_IN_DATE' and 'ERROR_FOR_DIVISION_BY_ZERO' sql modes should be used with strict mode. They will be merged with strict mode in a future release.
  result = self._query(query)

  result = self._query(query)

 2.三、断言判断

class TestIndex(TestCase):

    def test_idex(self):
        respose = self.client.get('/index/')
        self.assertEqual(respose.status_code,200)   #断言状态码是否为200
        self.assertTemplateUsed(respose,'new_index.html')  #断言模板是否可用
        # print(respose.status_code)

 运行结果

 monkey@MacBook-Pro-7  /usr/local/lib/python3.6/site-packages/guest  python3 manage.py test

/usr/local/lib/python3.6/site-packages/pymysql/cursors.py:161: Warning: 'NO_ZERO_DATE', 'NO_ZERO_IN_DATE' and 'ERROR_FOR_DIVISION_BY_ZERO' sql modes should be used with strict mode. They will be merged with strict mode in a future release.

 2.四、登陆case编写

from django.test import TestCase
from sign.models import Event,Guest   #导入引用的模块
from django.contrib.auth.models import User   #导入用户表（在写登陆单元测试case的时候须要建立一个用户来测试


class LoginActionTest(TestCase):

    def setUp(self):
        '''
        初始化测试数据：建立一个新的用户（与model层的初始化发布会、嘉宾表数据同样）
        :return:
        '''
        User.objects.create_user('admin','admin@mail.com','admin123456')

    def test_add_author_email(self):
        '''
        添加测试用户
        :return:
        '''
        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
        :return:
        '''
        response = self.client.post('/login_action/',{'input_username':'','input_password':''})
        self.assertEqual(response.status_code,200)
        self.assertIn(b'username or password error!',response.content)  #返回整个登陆页面信息


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

    def test_login_action_success(self):
        '''
        登陆成功
        :return:
        '''
        test_data = {'username':'admin','password':'admin123456'}
        response = self.c.post('/login_actiom/',data = test_data)
        self.assertEqual(response.status_code,302)

三、templates（模板）

只是一个HTML页面，不能进行测试，若是HTML页面有JS代码（script）能够进行测试

四、单独执行相对应的接口

python3 manage.py test sign

 

python3 manage.py test sign.tests.TestIndex
