Django无法导入测试模块

Question

尝试在Django for Beginners一书的简单Django pages应用程序上运行此测试文件。该书建议不涉及数据库导入SimpleTestCase bc。

# pages/tests.py

from django.test import SimpleTestCase

class PagesTests(SimpleTestCase):
    def test_home_page_status_code(self):
        response = self.client.get('/')
        self.assertEqual(response.status_code, 200)

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

并继续收到此错误消息：

ERROR: pages.tests (unittest.loader._FailedTest)

像django一样找不到测试模块....起初，我以为它变得混乱了，因为有两个名为“页面”的目录，所以我运气不佳地移动了tests.py文件。我还创建了一个单独的测试目录（“没有模块称为pages.test”）

我还使用了两个views.py文件（pages / views.py和pages / pages / views.py），使它们相同，因为我不确定是否是问题所在。大多数SO搜索不会产生Python 8的结果，因此想知道这是否可能是一个因素吗？

这是我的文件树：
