Support httpx

[gregbrowndev]

Hi,

I'm in the process of converting my requests-based application to httpx, and therefore also having to convert all the responses-based mocks within my tests. I wanted to avoid coupling to another client-specific test library like RESPX and instead use mocket.

However, I get an error when trying to instantiate httpx's AsyncClient. Here's a simple async pytest:

import json

import httpx
from mocket import async_mocketize
from mocket.mockhttp import Entry

@async_mocketize
async def test_mocket():
    async with httpx.AsyncClient() as client:
        url = "https://example.org/"
        data = {"message": "Hello"}

        Entry.single_register(
            Entry.GET,
            url,
            body=json.dumps(data),
            headers={'content-type': 'application/json'}
        )

        response = await client.get(url)

        assert response.json() == data

Stacktrack

Is httpx not supported? There are no references to it in the source or docs.

Thanks!

Hi @gregbrowndev, thanks for opening this issue. I don't think it has been tested before, but we should be able to make it work. I believe It's calling a method that I am not defining on FakeSSLContext side. You could try to add set_ciphers to this tuple. If you don't want to or cannot try, I'll give it a shot when I am done with work.

It may fail for a similar reason after you add that one, the fix would still be adding what's missing. I hope you won't see anything worse than that.

Thanks, @mindflayer, for the quick response on this!

I'll struggle to be able to try it today because I have plans after work. I'll try to investigate when I get the chance.

I tried the fix and it worked, but it looks like there is something more profound I have to investigate.

Here is a new version supporting httpx: https://pypi.org/project/mocket/3.10.7/
