如何测试使用 django 模板块？

{% block my_block %}
    <h1>Hello, World!</h1>
{% endblock %}

{% extends "base.html" %}

{% block my_block %}
    <h1>Hello, Django!</h1>
{% endblock %}

from django.shortcuts import render

def my_view(request):
    return render(request, 'my_template.html')

from django.test import TestCase
from django.template.loader import render_to_string

class MyBlockTestCase(TestCase):
    def test_my_block(self):
        # 渲染模板块
        rendered_block = render_to_string('my_block.html')

        # 断言模板块中的内容是否正确渲染
        self.assertIn('Hello, Django!', rendered_block)

python manage.py test
