Python 使用django.test.client测试应用程序http请求,获取错误
我们开始为我们的API(使用Django Rest框架创建)编写单元测试。我们决定从简单开始,使用内置的unittest和django.test.client类。我已经编写了一个测试的存根,它运行得很好:Python 使用django.test.client测试应用程序http请求,获取错误,python,django,unit-testing,Python,Django,Unit Testing,我们开始为我们的API(使用Django Rest框架创建)编写单元测试。我们决定从简单开始,使用内置的unittest和django.test.client类。我已经编写了一个测试的存根,它运行得很好: #!/usr/bin/env python # -*- coding: utf-8 -*- from __future__ import absolute_import import unittest # from django.test.client import Client clas

# Add test cases to suite
suite.addTests(unittest.makeSuite(TestGrowth))

unittest.TextTestRunner(verbosity=2).run(suite())
但是,只要我取消注释从django.test.client import client读取的行,我就会得到一个错误:

我使用下面的命令python./AccountGrowth.py
从vagrant shell内部运行测试
有人能解释一下为什么会发生这种情况吗?您没有通过Django的测试运行程序运行测试,它为您设置了所有这些。如果
块或它对run()
的显式调用是,那么您不需要,并且您应该通过/manage.py test
Daniel运行您的测试……目标是将它们作为大型套件的一部分运行,但我刚刚开始单元测试。当我尝试使用/manage.py test
从项目的根目录运行它时,它的行为似乎不一样。
if "DATABASE_URL" in os.environ:
# Parse database configuration from $DATABASE_URL
DATABASES = {
'default': dj_database_url.config()
}
else:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
'NAME': 'emmasocial', # Or path to database file if using sqlite3.
