我想测试一个资源.其响应取决于会话中的参数(已记录)
为了测试这个资源,我写了这些测试：
为了测试这个资源,我写了这些测试：
- import app
- import unittest
- class Test(unittest.TestCase):
- def setUp(self):
- self.app = app.app.test_client()
- def test_without_session(self):
- resp = self.app.get('/')
- self.assertEqual('without session',resp.data)
- def test_with_session(self):
- with self.app as c:
- with c.session_transaction() as sess:
- sess['logged'] = True
- resp = c.get('/')
- self.assertEqual('with session',resp.data)
- if __name__ == '__main__':
- unittest.main()
我的app.py是这样的：
- from flask import Flask,session
- app = Flask(__name__)
- @app.route('/')
- def home():
- if 'logged' in session:
- return 'with session'
- return 'without session'
- if __name__ == '__main__':
- app.run(debug=True)
当我运行测试我有这个错误：
- ERROR: test_pippo_with_session (__main__.Test)
- ----------------------------------------------------------------------
- Traceback (most recent call last):
- File "test_pippo.py",line 17,in test_pippo_with_session
- with c.session_transaction() as sess:
- File "/usr/lib/python2.7/contextlib.py",in __enter__
- return self.gen.next()
- File "/home/tommaso/repos/prova-flask/local/lib/python2.7/site-packages/flask/testing.py",line 74,in session_transaction
- raise RuntimeError('Session backend did not open a session. '
- RuntimeError: Session backend did not open a session. Check the configuration
我没有在google上找到任何解决方案.
解决方法
如果没有设置自定义的app.session_interface,那么你忘了设置一个
secret key：
- def setUp(self):
- app.config['SECRET_KEY'] = 'sekrit!'
- self.app = app.app.test_client()
这只是为测试设置了一个模拟秘密密钥,但是为了让您的应用程序工作,您需要生成一个生产秘密密钥,请参阅sessions section in the Quickstart documentation获取有关如何生成良好密钥的提示.
没有密钥,默认session implementation无法创建会话.
