hypermock alternatives and similar packages

Based on the "Testing" category

Do you think we are missing an alternative of hypermock or a related project?

Add another 'Testing' Package

README

HyperMock

HTTP request stubbing and expectation Elixir library. Intercepts HTTP calls and either returns a stubbed response if that request was stubbed or raises an error if a matching request was not found in the stubbed requests.

The idea is to provide tools to explicitly verify properties of the actual request rather than loose stubbing to return canned responses in your tests.

Unused stubs in your tests will also raise errors.

defmodule RequestTest do
  use HyperMock

  def fail do
    HyperMock.intercept do
      # No expectations have been set. This will raise an error.
      HTTPotion.get "http://example.com:3000/users", [body: "hello=world", headers: ["User-Agent": "My App"]]
    end
  end

  def yay do
    HyperMock.intercept do
      request  = %Request{ method: :get, uri: "http://lol.biz.info", headers: ["User-Agent": "My App"] }
      response = %Response{ body: "LOOOOOOOOOOOOL m8!" }

      stub_request request, response

      # This will return a HTTPotion.Response struct with a 200 status and body of "LOOOOOOOOOOOOL m8!"
      HTTPotion.get("http://lol.biz.info", headers: ["User-Agent": "My App"]) |> inspect |> IO.puts
    end
  end
end

Limitations

Only works with ibrowse synchronous requests right now. If you want to add support for asynchronous requests or another client open an issue and let's talk about it :)

If you have an idea please open an issue to start discussion first. The feature may have been discussed previously or in development.
