为我的烧瓶应用程序编写一些单元测试。当我尝试邮递员时，端点'/'有效并返回200，但是flask_testing给出AssertionError: 404 != 200

我已经设置了基本配置。

class BaseTestCase(TestCase):

    def create_app(self):
        app = flask(__name__)
        app.config['TESTING'] = True
        app.config['SQLALCHEMY_DATABASE_URI'] = "sqlite:///:memory:"
        app.config['JWT_SECRET_KEY'] = environ['JWT_SECRET_KEY']
        db = SQLAlchemy(app)
        db.init_app(app)
        return app

这是测试。

class flaskTestCase(BaseTestCase):

    def test_root(self):
        response = self.client.get('/')
        self.assertEquals(response.status_code,200)

测试输出
