WebMock: How to list (dump) all mocked responses?

If you make a web request in a test that isn't registered, WebMock will raise an exception, suggest how you can mock it, and list all the previously registered mocks:

I'd like to be able to dump all the registered mocks, just like the green-circled section above. How can I do that?

I've tried several invocations along these lines, without success:

snippet = WebMock::RequestSignatureSnippet.new(nil)
puts snippet.request_stubs

But I get this error on the first line:

 ArgumentError:
   wrong number of arguments (given 0, expected 1)
 # ./spec/models/user_spec.rb:113:in `new'

While I don't understand the wrong number of argument error, (I am passing it a nil, afterall) I suspect I'm just barking up the wrong tree and there's a simple way to do this. I haven't found any reference in the docs or searching online.

I could duplicate code and write my own dumper, but that seems silly.

Is there a simple way to get a formatted dump of all the registered webmocks, short of making a bad network request?

Solution

  • You could check the content the request_stub class variable defined for WebMock::StubRegistry:

    WebMock::StubRegistry.instance.request_stubs
=> [#<WebMock::RequestStub:.., ...]

    There you can use every RequestStub request_pattern method and their content.

    Using the RequestSignatureSnippet.

    What you need for initializing a RequestSignatureSnippet object is a RequestSignature object, which itself, expects to receive a HTTP method (as a String) and a URI (as a String as well):

    signature = WebMock::RequestSignature.new("GET", "http://example.com")
puts WebMock::RequestSignatureSnippet.new(signature).request_stubs
# "registered request stubs: ..."
