Test Steps:

There are three approaches

I.

Try the logging in method by following Visualize your applications via the Argo CD UI section in https://spaces.redhat.com/pages/viewpage.action?spaceKey=GITOPS&title=KAM+and+DevConsole+end+to+end+Tests 

II.

1. Install GitOps operator on your cluster
2. Navigate to Networking -> Routes in openshift-gitops project, click on the link that takes you to the ArgoCD UI page
3. Log In Via Openshift

III.

1. Remove dex configuration from argocd CR

$ oc -n openshift-gitops patch argocd openshift-gitops --type='json' -p='[{"op": "remove", "path": "/spec/sso" }]'

2. Add to the ArgoCD CR :

spec:
  extraConfig:
    oidc.tls.insecure.skip.verify: 'true' 
  sso:
    provider: keycloak
    keycloak:
      rootCA: "---BEGIN---END---"

3. Restart argocd server pod

$ oc rollout restart deployment.apps/openshift-gitops-server -n openshift-gitops

4. Wait for keycloak-1-deploy pod in openshift-gitops namespace to be completed

5. Navigate to Networking -> Routes in openshift-gitops project and click on the link that takes you to the ArgoCD UI page

6. LOG IN VIA KEYCLOAK, Log in with openshift and follow the instructions

Acceptance Criteria:

• Login is tested with all three approaches 
• Highest and lowest versions of supported OCP versions are covered
