아래는 제가 작성한 test.py와 models.py 입니다

from django.test import TestCase, Client
from bs4 import BeautifulSoup
from .models import Post
from django.utils import timezone
from django.contrib.auth.models import User

class TestView(TestCase):
    def setup(self):
        self.client = Client()
        self.author_000 = User.objects.create(username='Smith', password='nopassword')

    def test_post_list(self):
        response = self.client.get('/blog/')
        self.assertEqual(response.status_code, 200)

        soup = BeautifulSoup(response.content, 'html.parser')
        title = soup.title
        
        self.assertEqual(title.text, 'blog')

        navbar = soup.find('div', id='navbar')
        self.assertIn('Blog', navbar.text)
        self.assertIn('About Me', navbar.text)

        self.assertEqual(Post.objects.count(), 0)
        self.assertIn('아직 게시물이 없습니다', soup.body.text)

        post_000 = Post.objects.create(
            title = 'the first post',
            content = 'hello world',
            created = timezone.now(),
            author = self.author_000,
        )

        self.assertGreater(Post.objects.count(), 0)

from django.db import models
from django.contrib.auth.models import User


class Post(models.Model):
    title = models.CharField(max_length=30)
    content = models.TextField()
    head_image = models.ImageField(upload_to='blog/%Y/%m/%d/', blank=True)
    created = models.DateTimeField()
    author = models.ForeignKey(User, on_delete=models.CASCADE)

    def __str__(self):
        return str(self.title) + ' :: ' + str(self.author)

author에서만 말썽인걸보면 User.objects.create() 함수가 문제인건가 싶긴합니다..
