RSpec中的模拟请求超时

Question

I have a class that makes a request to another service and I want to test error handing around that request.

The code looks like this:

  response = RequestObject.post #this triggers a HTTP request

  LocalObject.update(foreign_id: response.id, retrieved_at: Time.current )

In my tests I stub the request out and return JSON on success, but I want to test that if that response raises an error that the :foreign_id and :retrieved_at aren't set.

I stub the successful request like this:

allow(RequestObject).to receive(:post).and_return({id: 1,})

What's a good way to mock RequestObject raising a timeout error?

(I'm using the Faraday gem for my requests)

Answer 1

You can use #and_raise to mock an error.

allow(RequestObject).to receive(:post).and_raise(SomeError)

That should allow you to test that code path.
