12、Django_test

1、概述

不一樣的項目類型裏面的單元測試基本不一樣

2、測試項目分析

一、models.py頁面：模型頁面

1.一、tests.py文件裏面寫入case

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

class ModelsTest(TestCase): #建立測試類，繼承Django下面的TestCase方法

    def test_event(self):  #建立測試類
        Event.objects.create(id=1, name="oneplus 3 event", status=True, limit=2000,
                             address='shenzhen', start_time='2016-08-31 02:18:22')   #數據初始化，建立一條發佈會數據來提供後面進行查找
        results =  Event.objects.all()  #調用，並非真正的去查找相對應的數據，須要在前面先建立發佈會的字段才能夠查找到
        print(results)

 1.二、終端進入到相對應的目錄，而且使用Test方法運行腳本

 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)
/usr/local/lib/python3.6/site-packages/pymysql/cursors.py:161: Warning: Changing sql mode 'NO_AUTO_CREATE_USER' is deprecated. It will be removed in a future release.
  result = self._query(query)

  result = self._query(query)

 1.三、運行原理

跟上面的unittest原理同樣

先找代碼中有沒有繼承Django中Test下面的TestCase類

再查找定義的方法中是否有test開頭的方法，若是有的話就執行

case運行的前後順序爲：經過ASCII碼的排序進行排序運行

初始化的數據並不會到數據庫裏面，只是提供測試操做

1.四、case的斷言操做

tests.py文件

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

class ModelsTest(TestCase): #建立測試類，繼承Django下面的TestCase方法

    def test_event(self):  #建立測試類
        Event.objects.create(id=1, name="test1", status=True, limit=2000,
                             address='shenzhen', start_time='2016-08-31 02:18:22')   #初始化測試數據，供下面查詢使用，這條數據並不會直接到數據庫裏面，只是提供測試查詢須要
        results =  Event.objects.get(name = 'test1')  #查詢相對應的方式不會真正的去數據庫查詢數據，須要經過上面的方法建立數據
        print(results.limit)
        print(results.address)
        self.assertEqual(results.limit,2000)  #斷言查詢出來的數據是否limit =  2000
        self.assertEqual(results.address,'shenzhen')   #斷言查詢出來的數據 是否address = 'shenzhen'

終端運行結果

 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   #導入引用的模塊
# Create your tests here.

class ModelsTest(TestCase): #建立測試類，繼承Django下面的TestCase方法

    def setUp(self):
        #初始化發佈會數據
        Event.objects.create(id=1, name="test1", status=True, limit=2000,
                             address='shenzhen', start_time='2016-08-31 02:18:22')
        #初始化嘉賓表數據
        Guest.objects.create(id=2, event_id=1, realname='alen',
                             phone='13711001101', email='alen@mail.com', sign=False)

    #發佈會的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')

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

 終端頁面

 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.

  result = self._query(query)

二、views.py頁面：視圖頁面

2.一、初始化測試環境

終端進入shell模式

導入Client類，模擬post、get請求，加入路徑，若是返回碼爲200則表示成功，創建了測試環境

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)

>>> c = Client()
>>> response = c.get("/index/")    #相似於模擬界面自動化測試的方法，加入相對應的跳轉後綴，模擬index頁面登陸效果
>>> response.status_code   #獲取返回碼
200

 2.二、測試case編寫

index頁面登陸case編寫

class TestIndex(TestCase):

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

 運行結果

 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)

 2.三、斷言判斷

class TestIndex(TestCase):

    def test_idex(self):
        respose = self.client.get('/index/')
        self.assertEqual(respose.status_code,200)   #斷言狀態碼是否爲200
        self.assertTemplateUsed(respose,'new_index.html')  #斷言模板是否可用
        # print(respose.status_code)

 運行結果

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

 2.四、登陸case編寫

from django.test import TestCase
from sign.models import Event,Guest   #導入引用的模塊
from django.contrib.auth.models import User   #導入用戶表（在寫登陸單元測試case的時候須要建立一個用戶來測試


class LoginActionTest(TestCase):

    def setUp(self):
        '''
        初始化測試數據：建立一個新的用戶（與model層的初始化發佈會、嘉賓表數據同樣）
        :return:
        '''
        User.objects.create_user('admin','admin@mail.com','admin123456')

    def test_add_author_email(self):
        '''
        添加測試用戶
        :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):
        '''
        用戶名、密碼爲空
        :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)  #返回整個登陸頁面信息


    def test_login_action_username_password_error(self):
        '''
        用戶名、密碼錯誤
        :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):
        '''
        登陸成功
        :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）

只是一個HTML頁面，不能進行測試，若是HTML頁面有JS代碼（script）能夠進行測試

四、單獨執行相對應的接口

python3 manage.py test sign

 

python3 manage.py test sign.tests.TestIndex
