使用rails3模拟外部API对象

Question

我想模拟/存根:

@the_bill = GovKit::OpenCongress::Bill.find_by_idents("112-s368").first

用于我的测试.

返回我想要为我的测试目的修复的以下对象:

--- !ruby/object:GovKit::OpenCongress::Bill 
bill_type: s
co_sponsors: 
- !ruby/object:GovKit::OpenCongress::Person {}

我已经尝试过Factory_girl(不能做,不是基于模型的对象),Fabrication(仍然是相同的问题)和OpenStruct,可能是可能的,但是在将yaml转换为OpenStruct并将模拟放在正确的位置时遇到了麻烦.

现在,我正在我的测试中进行api调用,而不是我想要的.我在想webmock是我的解决方案,但我在文档中找不到如何只加载一个简单的对象.

尝试使用VCR模拟API.大约6个月前,我有完全相同的问题,最近才发现这个库.它完全符合您的需要,将缓存对象以便稍后进行测试,但也可以定期自动刷新它们.到目前为止,它已经找到了我为此找到的最佳解决方案.
