烧瓶pytest测试数据库

Question

我正在尝试为我的应用程序编写一些测试。我可以测试不包含与db相关的任何内容的URL。

@pytest.fixture
def client():
    """
    Load pytest fixture.
    :return: test_client()
    """
    # yield application.test_client()

    db_fd, application.config['DATABASE'] = tempfile.mkstemp()
    db.create_all()
    application.config['TESTING'] = True
    client = application.test_client()

    yield client

    os.unlink(application.config['DATABASE'])

我的测试文件：

def test_membership_register(client):
    """Test entry point of website."""
    rv = client.get('/register')

    new_user = User(
            username='test_user_1',
            email='test_email@test1.com',
            password='test1_Password',
        )

    db.session.add(new_user)
    db.session.commit()

    assert 200 == rv.status_code

错误：

E sqlalchemy.exc.InvalidRequestError：已为此MetaData实例定义表'membership_user'。指定'extend_existing = True'重新定义现有Table对象上的选项和列。
