Conformance test HTTPRouteWeight is Failing

[fabian4]

What happened:

As HTTPRouteWeight test is Failing in nginx/nginx-gateway-fabric#3797.

What you expected to happen:

HTTPRouteWeight test pass.

How to reproduce it (as minimally and precisely as possible):

https://github.com/nginx/nginx-gateway-fabric/actions/runs/17256977734/job/48971158299

Anything else we need to know?:

As http.Response.StatusCode is Deprecated in #4010 and although there is a workaround at

gateway-api/conformance/utils/http/http.go

Lines 144 to 147 in d28cd59

	// if the deprecated field StatusCode is set, append it to StatusCodes for backwards compatibility
	if expected.Response.StatusCode != 0 {
	expected.Response.StatusCodes = append(expected.Response.StatusCodes, expected.Response.StatusCode)
	}

But in HTTPRouteWeight Test we call http.CompareRoundTrip() directlly

gateway-api/conformance/tests/httproute-weight.go

Lines 112 to 114 in d28cd59

	if err := http.CompareRoundTrip(t, &req, cReq, cRes, expected); err != nil {
	return fmt.Errorf("response expectation failed for request: %w", err)
	}

@fabian4 thanks for reporting and sorry for the inconveniences. It’s really appreciated that the NGINX project is essentially integration testing our conformance suite.
