显然，失败是由我添加的函数中的这一行引起的:
> assert_that(result.status_code, equal_to(400), invalid_body)
给出以下错误消息:
File "/usr/lib/python3.7/json/encoder.py", line 179, in default
raise TypeError(f'Object of type {o.__class__.__name__} '
TypeError: Object of type Mock is not JSON serializable
我尝试了一些通过搜索/查找问题找到的解决方案，但无法解决问题。请帮我解决一下，谢谢。
P.S:原始代码位于以下 github 存储库中:
最佳答案
对于任何与我面临同样问题的人，我通过更改我的字典声明找到了解决方案，如下所示:
invalid_bodies = [
('address', {'address':
'line_1':'',
'line_2':'',
'city':'',
'state':'',
'zip_code':'',
'country':'',
}),
]
我通过记录输入和预期的断言输出找到了解决方案；我注意到断言失败了，因为它需要一个 OrderedDict 对象而不是 dictionary。
显然，不接受使用 python keyworkd dict 声明您的字典(不是 JSON 可序列化；它将其转换为 OrderedDict 类型)。另外，我删除了我拥有的第二个主体(带有 None 地址字段的字典)。
关于python - 类型错误 : Object of type Mock is not JSON serializable，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/70764110/
