Test failure due to httpx change in 0.28

[mjpieters]

In version 0.27, httpx deprecated the app keyword argument:

Deprecated

• The app=... shortcut has been deprecated. Use the explicit style of transport=httpx.WSGITransport() or transport=httpx.ASGITransport() instead.

and in version 0.28, the deprecated keyword was removed:

The following changes are also included:

...

• The deprecated app argument has now been removed.

The ariadne-codegen tests use this keyword argument in the main.test_generated_client::http_client fixture:

ariadne-codegen/tests/main/test_generated_client.py

Lines 47 to 49 in 11bfe35

	@pytest.fixture
	def http_client():
	return AsyncClient(base_url="http://127.0.0.1:8000", app=api_app)

Luckily, the fix is fairly simple and works across all httpx versions that ariadne-codegen can be used with (0.23 and up); create a ASGITransport() instance and pass that in as the transport keyword argument:

@pytest.fixture
def http_client():
    transport = ASGITransport(app=api_app)
    return AsyncClient(base_url="http://127.0.0.1:8000", transport=transport)
