django中的view测试和models测试样例

感觉用model_mommy比factory_boy要好些。

如果Models.py如下：

from django.db import models
from django.contrib.auth.models import User
# Create your models here.

class Board(models.Model):
    name = models.CharField(max_length=30, unique=True)
    description = models.CharField(max_length=100)

    def __str__(self):
        return self.name

class Topic(models.Model):
    subject = models.CharField(max_length=255)
    last_updated = models.DateTimeField(auto_now_add=True)
    board = models.ForeignKey(Board, related_name='topics', on_delete=models.CASCADE)
    started = models.ForeignKey(User, related_name='topics', on_delete=models.CASCADE)

    def __str__(self):
        return self.subject

class Post(models.Model):
    message = models.TextField(max_length=4000)
    topic = models.ForeignKey(Topic, related_name='posts',  on_delete=models.CASCADE)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(null=True)
    created_by = models.ForeignKey(User, related_name='posts',  on_delete=models.CASCADE)
    updated_by = models.ForeignKey(User, null=True, related_name='+',  on_delete=models.CASCADE)

    def __str__(self):
        return self.message

则单元测试如下：

from django.test import TestCase
from django.urls import resolve, reverse
from boards.views import home
from model_mommy import mommy
from boards.models import Board, Topic, Post
# Create your tests here.

class HomeTests(TestCase):
    def test_home_view_status_code(self):
        url = reverse('home')
        response = self.client.get(url)
        self.assertEqual(response.status_code, 200)

    def test_home_url_resolves_home_view(self):
        view = resolve('/')
        self.assertEqual(view.func, home)

class BoardTestMommy(TestCase):

    def test_board_creation_mommy(self):
        board = mommy.make(Board)
        self.assertTrue(isinstance(board, Board))
        self.assertEqual(board.__str__(), board.name)

class TopicTestMommy(TestCase):

    def test_topic_creation_mommy(self):
        new_toipic = mommy.make('boards.Topic')
        self.assertTrue(isinstance(new_toipic, Topic))
        self.assertEqual(new_toipic.__str__(), new_toipic.subject)

class PostTestMommy(TestCase):

    def test_topic_creation_mommy(self):
        new_post = mommy.make('boards.Post')
        self.assertTrue(isinstance(new_post, Post))
        self.assertEqual(new_post.__str__(), new_post.message)
