Django 单元测试Demo

For Development

1) git clone [email protected]:alecchyi/DjDemo.git

2) cd DjDemo 

3) update database settings

3) python manage.py syncdb

4) python manage.py runserver 0.0.0.0:8000

For Testing in unittest

1. create tests.py in your app, such as core/tests.py

But the pre-condition is you have a models.py

2. add test code in tests.py

   1）测试登录表单

  import LoginForm

  f = LoginForm({}) #表单数据为空

  使用f.is_valid() 判断表单是否有效

  f = LoginForm({'username':'aaaa', 'password': '123456'})  #数据正常的情况

  self.assertTrue(f.is_valid(),"输入的信息有误")#如果表单数据有效，f,is_valid()返回True

  f = LoginForm({'username':'aaaa111111111111111111', 'password': '123456'})  #用户名输入长度过长的情况

  如果表单数据有效，f,is_valid()返回False

  self.assertFalse(f.is_valid(),"输入的用户名长度过长")

   2）测试模型操作

  t = {'username': "teacher_01", 'password': '12345611111111111111111111111111111111111111111111111122222222222222222222222222', 'status':0}

       with self.assertRaises(Exception):   #验证字段长度

           Member.objects.get_or_create(**t)

       with self.assertRaises(Exception):

            Member.objects.get(username='teacher_01')

        members = Member.objects.all()

        self.assertEqual(members.count(), 1, "count is 1")

   3）测试登录逻辑

  from django.test.client import Client

  c = Client()

  response = c.post("/login",{'username':'ruby', 'password': '123456'})

  self.assertEqual(response.status_code, 200)  #测试通过

   4）测试http请求和http响应

   from django.test.client import Client

  c = Client()

  response = c.get("/detail",{'xxxx':'eeeee'})

  self.assertEqual(response.content,'yyyy') #如果请求的方法是get,判断返回的结果是否正确

  self.assertEqual("yyy",response.context["key"]) #如果页面是render新的模板，并且有传递数据变量，可以使用这个判断

3. run test command  

cd project_dir && python manage.py test app_name   #测试对应app的所有脚本

python manage.py test core.tests.UserTest.test_login_request #执行测试某个具体的功能

4. add fixtures data in tests.py

    tests.py 的测试类是基础django.test.TestCase,所以会有一些继承的方法，比如

    setUp: 可以把一些测试数据定义在这里

    tearDown:测试完成销毁测试数据

5. add log info in test code

import logging

logger = logging.getLogger("django")

logger.debug("xxxxxxx")

cat logs/debug.log

6. custom assert function

    assert_xxx_xxxx()
