I want to add some regression tests for some bugs I just found. How would I go about doing so?

推荐答案

这是我的操作方法(摘录自

Here's how I do it (extracted from my django-multiforloop):

from django.test import TestCase
from django.template import Context, Template

class TagTests(TestCase):
    def tag_test(self, template, context, output):
        t = Template('{% load multifor %}'+template)
        c = Context(context)
        self.assertEqual(t.render(c), output)
    def test_for_tag_multi(self):
        template = "{% for x in x_list; y in y_list %}{{ x }}:{{ y }}/{% endfor %}"
        context = {"x_list": ('one', 1, 'carrot'), "y_list": ('two', 2, 'orange')}
        output = u"one:two/1:2/carrot:orange/"
        self.tag_test(template, context, output)

这与

This is fairly similar to how tests are laid out in Django's own test suite, but without relying on django's somewhat complicated testing machinery.
