Unclear what I'm missing using assertIn for Article List

Can't see what I'm missing here.

articles/tests.py 
import datetime

from django.core.urlresolvers import reverse
from django.test import TestCase

from .models import Article, Writer

class ArticleListViewTestCase(TestCase):
    '''Tests for the Article list view'''

    def setUp(self):
        self.writer = Writer.objects.create(
            name='Kenneth Love',
            email='kenneth@teamtreehouse.com',
            bio='Your friendly, local Python teacher'
        )
        self.article = Article.objects.create(
          writer=self.writer,
          headline='Article 0',
          content='Something about 0',
          publish_date=datetime.datetime.today()
        )
        for x in range(1, 3):
            Article.objects.create(
                writer=self.writer,
                headline='Article {}'.format(x),
                content='Something about {}'.format(x),
                publish_date=datetime.datetime.today()
            )
    def test_articles_in_dict(self):
        resp = self.client.get(reverse('articles:list'))
        self.assertEqual(resp.status_code, 200)
        self.assertIn(self.article, resp.context(['articles']))
articles/views.py 
from django.shortcuts import get_object_or_404, render

from .models import Article, Writer


def article_list(request):
    articles = Article.objects.all()
    return render(request, 'articles/article_list.html', {'articles': articles})


def article_detail(request, pk):
    article = get_object_or_404(Article, pk=pk)
    return render(request, 'articles/article_detail.html', {'article': article})


def writer_detail(request, pk):
    writer = get_object_or_404(Writer, pk=pk)
    return render(request, 'articles/writer_detail.html', {'writer': writer})

To me, it looks what you did with assertIn should have worked.

I would probably use a slightly simpler test to make sure the template or namespace isn't misbehaving. Thus, looking to find the article.headline (I assume you are showing that in your rendered template) in the resp might help diagnose what is going amiss. If that test fails, then your template rendering is not working as expected.

def test_article_simple(self):
        resp = self.client.get(reverse('articles:list'))
        self.assertEqual(resp.status_code, 200)  # if this passed, namespace worked and page responded
        self.assertTemplateUsed(resp, 'articles/article_list.html') # if this passes, we used our expected template
        self.assertContains(resp, self.article.headline) # if this passes, we saw one headline
