Hi @antoniomerlin. Thanks for your PR.

I'm waiting for a jaegertracing 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. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Hi, thanks for reviewing, i've modified the changes just a query you already having test mentioning this scenario :-

func TestQueryIngressClass(t *testing.T) {
	jaeger := v1.NewJaeger(types.NamespacedName{Name: "TestQueryIngressClass"})
	jaegerNoIngressNoClass := v1.NewJaeger(types.NamespacedName{Name: "TestQueryIngressNoClass"})

	inressClassName := "nginx"
	jaeger.Spec.Ingress.IngressClassName = &inressClassName

	ingress := NewQueryIngress(jaeger)
	ingressNoClass := NewQueryIngress(jaegerNoIngressNoClass)

	dep := ingress.Get()

	assert.NotNil(t, dep.Spec.IngressClassName)
	assert.Equal(t, "nginx", *dep.Spec.IngressClassName)
	assert.Nil(t, ingressNoClass.Get().Spec.IngressClassName)
}

pkg/ingress/query_test.go do i need to write again or can use existing one or do any modification in this ?

You can complete that test to set a custom value and check if the custom value is properly set.

okay thanks.

Hi, I've modified that test case to set ingressNoClass to default or nginx available ingress controller. And if any error or unable to find any ingress controller installed then it would be remain empty.
