标签: python testing flask config

在为我的Flask应用程序编写测试时,我在尝试设置Flask配置设置时遇到了一个问题。

通常,我这样做:

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.assertTrue(self.app.config['SECRET_KEY'] is 'secret_key')
        self.assertTrue(self.app.config['DEBUG'] is True)

导致错误

  

AttributeError:' FlaskClient'对象没有属性' config'

只有从调试中我才看到没有" config"相反,我必须去self.app.application.config才能让它发挥作用。

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.assertTrue(self.app.application.config['SECRET_KEY'] is 'secret_key')
        self.assertTrue(self.app.application.config['DEBUG'] is True)

我做了什么,Flask是否在更新中更改了此内容,还是有更好的方法来执行此操作?

编辑:错误地在顶部块中发布代码,现在正确

答案 0 :(得分:2)

生产中的app类型为flask.app.Flask,而您在测试中使用的flask.testing.FlaskClientself.app.application.config,它们是2个不同的对象。使用self.app = app.test_client()访问配置的方式是正确且唯一的方法,因为当您设置c/Users/631/AppData/Local/Continuum/Anaconda21 时,它会返回FlaskClient实例。

看看流动的:FlaskClienttest_client

这里是您测试客户端本身时可以做的提示:

import unittest
from app import app


class Tests(unittest.TestCase):

    # setup client
    def setUp(self):
        self.client = app.test_client()

    # generating proposital error to see methods available by self.client
    def test_app_configs(self):
        print(dir(self.client))
        self.assertEqual(False, True)

在终端中执行py.test会导致:

self = <test_app.Tests testMethod=test_if_inside_aws>

    def test_app_configs(self):
        print(dir(self.client))
>       self.assertEqual(False, True)
E       AssertionError: False != True

如上面@ gyx-hh所述,application有一个self.client方法可用。现在,执行相同的过程,但现在检查self.client.application的方法:

然后,您通常需要很多东西,并且有config属性。
