can not mock httpx

[elonzh]

HTTPretty is an awesome testing tool but it doesn't support mock httpx. Maybe we should consider supporting httpx?

demo code:

import httpretty
import httpx


def test_one():
    httpretty.enable()  # enable HTTPretty so that it will monkey patch the socket module
    httpretty.register_uri(httpretty.GET, "http://yipit.com/",
                           body="Find the best daily deals")

    response = httpx.get('http://yipit.com')

    assert response.text == "Find the best daily deals"

    httpretty.disable()  # disable afterwards, so that you will have no problems in code that uses that socket module
    httpretty.reset()  # reset HTTPretty state (clean up registered urls and request history)


if __name__ == '__main__':
    test_one()

output:

The above exception was the direct cause of the following exception:

For now, you could consider https://github.com/lundberg/respx which seems like the recommended way of mocking httpx.

I know that, but I prefer HTTPretty because it is more generic like vcrpy

Thanks for the report @elonzh I'll work on this soon.
