None type doesn't work in data matching as of v0.21.0

[slingshotvfx]

As of the latest version v0.21.0, None values in data lookups don't work:

import httpx
import respx


@respx.mock
def test():
    data = {"test": None}

    respx.post("http://test.com", data=data).respond()

    response = httpx.post("http://test.com", data=data)

    assert response.status_code == 200


if __name__ == "__main__":
    test()

output:

respx.models.AllMockedAssertionError: RESPX: <Request('POST', 'http://test.com/')> not mocked!

This test passes successfully in v0.20.2

The following do work:

    data = {"test": ""}
    respx.post("http://test.com", data=data).respond()
    response = httpx.post("http://test.com", data=data)

    respx.post("http://test.com", data={"test": ""}).respond()
    response = httpx.post("http://test.com", data={"test": None})

So there's just a bug somewhere translating None to ""

Thanks, hopefully a simple fix

@slingshotvfx please try #259 and see if it solves your issue

Not sure if it's related but I also encounter issues when I run (as a unittest.TestCase method):

    @respx.mock
    def test_file_upload(self):

        FILE_DATA = {
            "upload": ("image/png", io.BytesIO(b"some image content"), "image/png")
        }

        respx.patch("https://api.example.com/endpoint/123", files=FILE_DATA)

        httpx.patch("https://api.example.com/endpoint/123", files=FILE_DATA)

This raises:

raise AllMockedAssertionError(f"RESPX: {request!r} not mocked!")
respx.models.AllMockedAssertionError: RESPX: <Request('PATCH', 'https://api.example.com/endpoint/123')> not mocked!

@pierremonico this is not related and is certainly a bug in the new files pattern feature that was added in 0.21.0.

Please open a new issue with your test example. My bet is that the pattern doesn't handle BytesIO, which should be a simple fix.

@lundberg #259 fixes my issue. Thanks for looking into it!
