lemoncheesecake is an end-to-end test framework for Python that brings trust around test results. It allows test developers to be very explicit about what their tests really do with logging, matchers, file attachments, etc..

Here is a test example:

.. code-block:: python

import json
import requests

import lemoncheesecake.api as lcc
from lemoncheesecake.matching import *

URL  = "https://api.github.com/orgs/lemoncheesecake"

@lcc.suite("Github tests")
class github:
    @lcc.test("Test Organization end-point")
    def organization(self):
        lcc.set_step("Get lemoncheesecake organization information")
        lcc.log_info("GET %s" % URL)
        resp = requests.get(URL)
        require_that("HTTP code", resp.status_code, is_(200))
        data = resp.json()
        lcc.log_info("Response\n%s" % json.dumps(data, indent=4))

        lcc.set_step("Check API response")
        check_that_in(
            data,
            "type", is_("Organization"),
            "id", is_integer(),
            "description", is_not_none(),
            "login", is_(present()),
            "created_at", match_pattern("^\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}Z$"),
            "has_organization_projects", is_true(),
            "followers", is_(greater_than_or_equal_to(0)),
            "following", is_(greater_than_or_equal_to(0)),
            "repos_url", ends_with("/repos"),
            "issues_url", ends_with("/issues"),
            "events_url", ends_with("/events"),
            "hooks_url", ends_with("/hooks"),
            "members_url", ends_with("/members{/member}"),
            "public_members_url", ends_with("/public_members{/member}")
        )

And here are the corresponding test results:
