'Flask'对象没有登录单元测试的属性'post'错误

Question

我正在尝试使用烧瓶测试我的登录功能。 我也在关注 Flask 文档进行测试。test_login()函数会引发AttributeError: 'Flask' object has no attribute 'post'。 为什么我会收到此错误？

Traceback (most recent call last):
  File "/home/lucas/PycharmProjects/FYP/Shares/tutorial/steps/test.py", line 57, in test_login_logout
rv = self.login('lucas', 'test') <br> <br>
  File "/home/lucas/PycharmProjects/FYP/Shares/tutorial/steps/test.py", line 47, in login
return self.app.post('/login', data=dict(
AttributeError: 'Flask' object has no attribute 'post'

from flask.ext.testing import TestCase
from flask import Flask
from Shares import db
import manage
class test(TestCase):
def create_app(self):
    app = Flask(__name__)
    app.config['TESTING'] = True
    return app
SQLALCHEMY_DATABASE_URI = "sqlite://"
TESTING = True
def setUp(self):
    manage.initdb()

    db.session.remove()
    db.drop_all()
def test_adduser(self):
    user = User(username="test", email="[e-mail]")
    user2 = User(username="lucas", email="[e-mail]")
    db.session.add(user)
    db.session.commit()
    assert user in db.session
    assert user2 not in db.session
def login(self, username, password):
    return self.app.post('/login', data=dict(
        username=username,
        password=password
    ), follow_redirects=True)
def logout(self):
    return self.app.get('/logout', follow_redirects=True)
def test_login(self):
    rv = self.login('lucas', 'test')
    assert 'You were logged in' in rv.data

Answer 1

看起来 Flask-Testing 神奇地在 TestCase 实例上设置了一个名为 self.client 的特殊应用程序客户端对象。将所有self.app更改为self.client，它应该可以解决此问题。

例如：

def login(self, username, password):
    return self.app.post('/login', data=dict(
        username=username,
        password=password
    ), follow_redirects=True)

自：

def login(self, username, password):
        return self.client.post('/login', data=dict(
            username=username,
            password=password
        ), follow_redirects=True)

在为我的 Flask 应用程序编写测试时，我遇到了类似的问题。

只是从调试中我看到没有"配置"属性，而是我不得不去self.app.application.config

不知道为什么它丢失了，我通常总是像在生产代码中一样做self.app.config

import unittest
from factory import create_app

class ConfigTests(unittest.TestCase):
    def setUp(self):
        app = create_app('flask_test.cfg')
        app.testing = True
        self.app = app.test_client()
    def test_app_is_development(self):
        self.assertFalse(self.app.application.config['SECRET_KEY'] is 'secret_key')
        self.assertTrue(self.app.application.config['DEBUG'] is True)
