Link headers Example does not work

[tnk-dev]

https://httpretty.readthedocs.io/en/latest/introduction.html#link-headers

Does not work. It only registers the latest httpretty.register_uri !

import requests
from sure import expect
import httpretty

@httpretty.activate
def test_link_response():
    first_url = "http://foo-api.com/data"
    second_url = "http://foo-api.com/data?page=2"
    link_str = "<%s>; rel='next'" % second_url

    httpretty.register_uri(
        httpretty.GET,
        first_url,
        body='{"success": true}',
        status=200,
        content_type="text/json",
        adding_headers={"Link": link_str},
    )
    httpretty.register_uri(
        httpretty.GET,
        second_url,
        body='{"success": false}',
        status=500,
        content_type="text/json",
    )
    # Performs a request to `first_url` followed by some testing
    response = requests.get(first_url)
    expect(response.json()).to.equal({"success": True})
    expect(response.status_code).to.equal(200)
    next_url = response.links["next"]["url"]
    expect(next_url).to.equal(second_url)

    # Follow the next URL and perform some testing.
    response2 = requests.get(next_url)
    expect(response2.json()).to.equal({"success": False})
    expect(response2.status_code).to.equal(500)
