Python 单元测试详解 本文直接从常用的Python单元测试框架出发,分别对几种框架进行了简单的介绍和小结,然后介绍了 Mock 的框架,以及测试报告生成方式,并以具体代码示例进行说明,最后列举了一些常见问题。 一、常用 Python 单测框架 若你不想安装或不允许第三方库,那么unittest是最好也是唯一的选择。反之,pytest无疑是...

are already first-class features of the language In Python, it's considerably simpler to treat all attributes as public. This means the following: They should be well documented. They should properly reflect the state of the object; they shouldn't be temporary or transient values. In the rare...

You can usually pass other attributes in the context object for the function code to consume. post_invocation Called right after the function execution finishes. The function context, function invocation arguments, and invocation return object are passed to the extension. This implementation is a ...
