Pytest-HttpServer

pytest-httpserver is a python package which allows you to start a real HTTP server for your tests. The server can be configured programmatically to how to respond to requests.

Installation⚑

pip install pytest-httpserver

Usage⚑

import requests

def test_json_client(httpserver: HTTPServer):
    httpserver.expect_request("/foobar").respond_with_json({"foo": "bar"})
    assert requests.get(httpserver.url_for("/foobar")).json() == {'foo': 'bar'}

Specifying responses⚑

Once you have set up the expected request, it is required to set up the response which will be returned to the client.

In the example we used respond_with_json() but it is also possible to respond with an arbitrary content.

respond_with_data("Hello world!", content_type="text/plain")

In the example above, we are responding a text/plain content. You can specify the status also:

respond_with_data("Not found", status=404, content_type="text/plain")

Give a dynamic response⚑

If you need to produce dynamic content, use the respond_with_handler method, which accepts a callable (eg. a python function):

from werkzeug.wrappers import Response
from werkzeug.wrappers.request import Request

def my_handler(request: Request) -> Response:
    # here, examine the request object
    return Response("Hello world!")

respond_with_handler(my_handler)
