Django测试

一、今日学习内容概述

学习模块	重要程度	主要内容
测试基础	⭐⭐⭐⭐⭐	TestCase、断言方法
模型测试	⭐⭐⭐⭐⭐	模型方法、数据验证
视图测试	⭐⭐⭐⭐	请求处理、响应验证
表单测试	⭐⭐⭐⭐	表单验证、数据处理
覆盖率测试	⭐⭐⭐⭐	coverage配置、报告生成

二、测试基础示例

2.1 基本测试类

# tests/test_base.py
from django.test import TestCase
from django.contrib.auth.models import User
from .models import Articleclass ArticleTestCase(TestCase):def setUp(self):"""测试前准备工作"""# 创建测试用户self.user = User.objects.create_user(username='testuser',email='test@example.com',password='testpass123')# 创建测试文章self.article = Article.objects.create(title='Test Article',content='Test Content',author=self.user)def tearDown(self):"""测试后清理工作"""self.user.delete()self.article.delete()def test_article_creation(self):"""测试文章创建"""self.assertEqual(self.article.title, 'Test Article')self.assertEqual(self.article.author, self.user)def test_article_str_representation(self):"""测试文章字符串表示"""self.assertEqual(str(self.article), 'Test Article')

2.2 测试工具类

# tests/test_utils.py
import unittest
from django.test import TestCase
from .utils import calculate_reading_time, generate_slugclass UtilsTestCase(TestCase):def test_reading_time_calculation(self):"""测试阅读时间计算"""# 准备测试数据content = ' '.join(['word'] * 500)  # 500个单词# 调用测试函数reading_time = calculate_reading_time(content)# 验证结果（假设每分钟阅读200个单词）self.assertEqual(reading_time, 2.5)def test_slug_generation(self):"""测试slug生成"""test_cases = [('Hello World', 'hello-world'),('测试文章', 'ce-shi-wen-zhang'),('Python & Django', 'python-django'),]for title, expected_slug in test_cases:with self.subTest(title=title):self.assertEqual(generate_slug(title), expected_slug)

三、模型测试示例

# tests/test_models.py
from django.test import TestCase
from django.core.exceptions import ValidationError
from django.utils import timezone
from .models import Article, Categoryclass ArticleModelTest(TestCase):@classmethoddef setUpTestData(cls):"""创建测试数据"""cls.category = Category.objects.create(name='Test Category')cls.article = Article.objects.create(title='Test Article',content='Test Content',category=cls.category,status='draft')def test_title_max_length(self):"""测试标题长度限制"""article = Article.objects.get(id=self.article.id)max_length = article._meta.get_field('title').max_lengthself.assertEqual(max_length, 200)def test_article_label(self):"""测试字段标签"""article = Article.objects.get(id=self.article.id)title_label = article._meta.get_field('title').verbose_nameself.assertEqual(title_label, '标题')def test_publish_article(self):"""测试文章发布功能"""article = Article.objects.get(id=self.article.id)article.publish()self.assertEqual(article.status, 'published')self.assertIsNotNone(article.published_at)def test_article_ordering(self):"""测试文章排序"""Article.objects.create(title='Second Article',content='Content',category=self.category,status='published')articles = Article.objects.all()self.assertEqual(articles[0].title, 'Second Article')

四、视图测试示例

# tests/test_views.py
from django.test import TestCase, Client
from django.urls import reverse
from django.contrib.auth.models import User
from .models import Articleclass ArticleViewsTest(TestCase):def setUp(self):self.client = Client()self.user = User.objects.create_user(username='testuser',password='testpass123')self.article = Article.objects.create(title='Test Article',content='Test Content',author=self.user)def test_article_list_view(self):"""测试文章列表视图"""response = self.client.get(reverse('article_list'))self.assertEqual(response.status_code, 200)self.assertTemplateUsed(response, 'articles/article_list.html')self.assertContains(response, 'Test Article')def test_article_detail_view(self):"""测试文章详情视图"""response = self.client.get(reverse('article_detail', args=[self.article.id]))self.assertEqual(response.status_code, 200)self.assertTemplateUsed(response, 'articles/article_detail.html')self.assertEqual(response.context['article'], self.article)def test_create_article_view(self):"""测试创建文章视图"""self.client.login(username='testuser', password='testpass123')response = self.client.post(reverse('article_create'), {'title': 'New Article','content': 'New Content',})self.assertEqual(response.status_code, 302)  # 重定向self.assertTrue(Article.objects.filter(title='New Article').exists())

五、表单测试示例

# tests/test_forms.py
from django.test import TestCase
from .forms import ArticleForm, CommentFormclass ArticleFormTest(TestCase):def test_article_form_valid_data(self):"""测试表单有效数据"""form = ArticleForm(data={'title': 'Test Article','content': 'Test Content','category': 1,'status': 'draft'})self.assertTrue(form.is_valid())def test_article_form_invalid_data(self):"""测试表单无效数据"""form = ArticleForm(data={})self.assertFalse(form.is_valid())self.assertEqual(len(form.errors), 3)  # title, content, category 必填def test_article_form_title_max_length(self):"""测试标题长度限制"""form = ArticleForm(data={'title': 'x' * 201,  # 超过最大长度'content': 'Test Content','category': 1})self.assertFalse(form.is_valid())self.assertIn('title', form.errors)

六、覆盖率测试配置

6.1 安装配置

# 安装coverage
pip install coverage# 运行测试并收集覆盖率数据
coverage run manage.py test# 生成覆盖率报告
coverage report
coverage html

6.2 配置文件

# .coveragerc
[run]
source = .
omit =*/migrations/**/tests/**/venv/*manage.py[report]
exclude_lines =pragma: no coverdef __repr__raise NotImplementedErrorif settings.DEBUGpass

七、测试流程图

在这里插入图片描述

八、高级测试技巧

8.1 异步测试

from django.test import TestCase
import asyncioclass AsyncTests(TestCase):async def test_async_view(self):"""测试异步视图"""response = await self.async_client.get('/async-view/')self.assertEqual(response.status_code, 200)async def test_async_task(self):"""测试异步任务"""result = await async_task()self.assertTrue(result)

8.2 测试fixtures

# tests/fixtures/test_data.json
[{"model": "app.category","pk": 1,"fields": {"name": "Test Category","description": "Test Description"}}
]# tests/test_with_fixtures.py
class CategoryTestCase(TestCase):fixtures = ['test_data.json']def test_category_exists(self):"""测试fixture数据加载"""category = Category.objects.get(pk=1)self.assertEqual(category.name, 'Test Category')
