I'm probably missing something obvious, but how is it possible to pass all tests with v1.0.0 per https://github.com/kubernetes-sigs/gateway-api/pull/2535/files#r1378650459?

/hold for clarification

[arkodg]

@robscott the current code in v1.0.0 made an extra assertion that the Route is not Accepted . This is true for Envoy Gateway.
However there is nothing in the spec to enforce that, so that check was removed. ptal at #2548 for more context
tldr - Envoy Gateway will pass all tests with or without that assertion

[robscott]

Thanks @arkodg! I guess the question was how that test could pass (Accepted == false) at the same time as a nearly identical test that requires Accepted to be true:

gateway-api/conformance/tests/httproute-invalid-backendref-nonexistent.go

Line 48 in 341c46e

gwAddr := kubernetes.GatewayAndHTTPRoutesMustBeAccepted(t, suite.Client, suite.TimeoutConfig, suite.ControllerName, kubernetes.NewGatewayRef(gwNN), routeNN)

Just trying to understand the difference here when this seems to be a blocker for many implementations to pass conformance on v1.0.0. Maybe Envoy Gateway is making a distinction between the two test cases that other implementations are not?

[arkodg]

Envoy Gateway defines its own custom reason (for the Route) for this case/test- NoReadyListeners

  - lastTransitionTime: "2023-10-27T01:38:14Z"
    message: There are no ready listeners for this parent ref
    observedGeneration: 1
    reason: NoReadyListeners
    status: "False"
    type: Accepted
  - lastTransitionTime: "2023-10-27T01:38:14Z"

The listener is not ready in this test because the cert is invalid

  - lastTransitionTime: "2023-10-27T01:38:14Z"
    message: Secret gateway-conformance-infra/does-not-exist does not exist.
    observedGeneration: 2
    reason: InvalidCertificateRef
    status: "False"
    type: ResolvedRefs
  - lastTransitionTime: "2023-10-27T01:38:14Z"
    message: Listener is invalid, see other Conditions for details.
    observedGeneration: 2
    reason: Invalid
    status: "False"
    type: Programmed

Got it, makes sense, thanks for the explanation @arkodg!
