Hi @arnaud-tincelin. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available [here](https://git.k8s.io/community/contributors/guide/pull-requests.md). If you have questions or suggestions related to my behavior, please file an issue against the [kubernetes-sigs/prow](https://github.com/kubernetes-sigs/prow/issues/new?title=Prow%20issue:) repository.

thank you @mlavacca, it's a lot clearer!

I am still working on the code based on your comments and I am trying to run the tests on an AKS with istio gateway or azure gateway but in both cases the tests end up in timeout. Is there something I am missing?

The tests seem to be stuck on this:

helpers.go:223: 2024-06-06T11:26:27.841628413+02:00: gateway-conformance-infra/gateway-add-listener Gateway not Accepted yet
    helpers.go:222: 2024-06-06T11:26:28.841559903+02:00: Accepted condition set to Status False with Reason Accepted, expected Status True
    helpers.go:222: 2024-06-06T11:26:28.841667255+02:00: Accepted was not in conditions list [[{Accepted False 1 2024-06-06 11:14:31 +0200 CEST Accepted Gateway does not have annotation to reference Application Gateway for Containers resource}]]

and I started the tests with

go test ./conformance -run TestConformance -args \
    --gateway-class=istio \ # or azure-alb-external
    --supported-features=Gateway,HTTPRoute,HTTPRouteBackendPathRedirect`
