chore: replace respx mocks with pytest-httpserver in tests

• Replace respx mocks with pytest-httpserver in tests

[Mantisus]

I chose pytest-httpserver as a testing tool. This is because the tests are too specific and do not allow the use of httpbin without breaking the test logic. At the same time, there are not enough tests to use uvicorn with complex endpoint logic.

I haven't deleted respx yet, as the timeout tests are quite specific to httpx. They should be considered separately after switching to impit.

I think it is good, but I am curious about the impit and those test_specific_timeouts_... tests

It's still just an idea. But I think mocking the ‘request’ method for ‘impit’ clients

will be something like:

from collections.abc import Iterator

import impit
import pytest

class EndOfTestError(Exception):
    """Custom exception that is raised after the relevant part of the code is executed to stop the test."""

@pytest.fixture
def patch_request(monkeypatch: pytest.MonkeyPatch) -> Iterator[list]:
    captured_calls = []
    
    def mock_request(*args, **kwargs):
        captured_calls.append({
            'args': args,
            'kwargs': kwargs,
            'timeout': kwargs.get('timeout')
        })
        raise EndOfTestError
    
    monkeypatch.setattr('impit.Client.request', mock_request)
    yield captured_calls
    monkeypatch.undo()

def test_dynamic_timeout_sync_client(patch_request: None) -> None:
    captured_calls = patch_request
    
    client = impit.Client()

    expected_timeouts = [1, 2, 4, 5]

    for timeout in expected_timeouts:
        with pytest.raises(EndOfTestError):
            client.request('GET', url="http://example.com", timeout=timeout)

    actual_timeouts = [call['timeout'] for call in captured_calls]
    assert actual_timeouts == expected_timeouts

I believe this approach is the most promising.
