如何在测试烧瓶应用程序时发出请求时传递修改后的或自定义的会话？

Question

我采用了手册中的代码

http://flask.pocoo.org/docs/0.10/testing/#accessing-and-modifying-sessions

with app.test_client() as c:
with c.session_transaction() as sess:
    sess['a_key'] = 'a value'

# once this is reached the session was stored

下面介绍了我使用这种方法的项目的核心。

from unittest import TestCase as Base


class TestCase(Base):
    @classmethod
    def setUpClass(cls):
        cls.app = create_app()
        cls.app.config['TESTING'] = True
        cls.client = cls.app.test_client()
        cls._ctx = cls.app.test_request_context()
        cls._ctx.push()


class TestModel(TestCase):

    def test_adding_comments_logged_user(self):
        with self.app.test_client() as c:
            with c.session_transaction() as sess:
                sess['user_id'] = 1
            self.app.preprocess_request()
            response = self.client.get('/')

        assert 'Yahooo!!!' in response.data


if __name__ == "__main__":
    import unittest    
    unittest.main()

__init__.py

# Main init file.
from flask import Flask, render_template, g, session


DEBUG = False
TESTING = False

SECRET_KEY = "jd&%G#43WG~dn6"
SITE_TITLE = "TEST"


def index():
    return render_template('index.html', user=g.user)


def load_user():
    if 'user_id' not in session.keys():
        g.user = 'None'
    else:
        g.user = 'Yahooo!!!'


def create_app():
    app = Flask(__name__)
    app.config.from_object(__name__)
    app.before_request(load_user)
    app.add_url_rule('/', 'index', index)

    return app

index.html

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8">
    <title>I Need Help</title>
</head>
<body>
{{ user }}
</body>
</html>

很遗憾，我无法获取变量g.user的值'Yahooo!!!'。我无法获得函数 load_user 运行 test.py 语句的 'else' 分支 'if' .

解决方案基于类似问题中提供的代码：

代替行

with self.app.test_client() as c:

在'test.py'我应该写

with self.client as c:

不过，我还是不明白这些行的区别。
