Unit Testing for a Python RESTful API
提问by Josh Usre
What's the best way to perform Unit Testing for a RESTful API that includes email functionality (lost passwords, user activation) in Python?
在 Python 中对包含电子邮件功能（丢失密码、用户激活）的 RESTful API 执行单元测试的最佳方法是什么？
Everything is done via HTTP POST / GET and at this time, authentication isn't involved.
一切都是通过 HTTP POST / GET 完成的，此时不涉及身份验证。
Should I just use the requestslibrary and manually do everything I want? Is it possible to use requeststo automate the parts of my Unit Testing that involves email?
我应该只使用requests图书馆并手动完成我想做的一切吗？是否可以用于requests自动化我的单元测试中涉及电子邮件的部分？

Often the web framework that you use to implement the REST api will also offer unit testing support. For example:
通常，用于实现 REST api 的 Web 框架也会提供单元测试支持。例如：
- Flask: http://flask.pocoo.org/docs/latest/testing/
- Django: http://django-testing-docs.readthedocs.org/en/latest/views.html
- 烧瓶：http: //flask.pocoo.org/docs/latest/testing/
- Django：http: //django-testing-docs.readthedocs.org/en/latest/views.html
These test classes are shortcuts which plug the request directly into the framework's Url dispatcher. That saves you the hassle of finding a free port, spawning a "real" server and connecting the http client from your unit test.
这些测试类是将请求直接插入框架的 Url 调度程序的快捷方式。这样可以省去寻找空闲端口、生成“真实”服务器以及从单元测试连接 http 客户端的麻烦。
As for the e-mail sending: I would mock that part in the TestCase.setUpmethod. Just change the reference to the e-mail sending module / class to another module/class which loops the outgoing e-mail back to the unit test for evaluation rather than e-mailing.
至于发送电子邮件：我会在TestCase.setUp方法中模拟该部分。只需将对电子邮件发送模块/类的引用更改为另一个模块/类，该模块/类将外发电子邮件循环回单元测试进行评估，而不是发送电子邮件。
