How to set up and validate locally

1. Setup gdk to simulate SaaS - https://docs.gitlab.com/ee/development/ee_features.html#simulate-a-saas-instance and restart GDK.

2. Sign in. Create new group.

3. In rails console create / update new GitLab subscription for your new group:

      bin/rails c
      namespace = Group.last
      gitlab_subscription = namespace.gitlab_subscription # find or create a new one if needed
      gitlab_subscription.update(hosted_plan: Plan.find_by(name: 'premium'))

4. To test Duo Pro

      bin/rails c
      add_on_purchase = GitlabSubscriptions::AddOnPurchase.create(subscription_add_on_id: GitlabSubscriptions::AddOn.find_by(name: 'code_suggestions').id, namespace: Group.last, started_at: 55.days.ago, expires_on: (Date.today + 5.days), trial: true, quantity: 1, purchase_xid: '1', organization_id: 1)
   

5. To test trial end period + progress bar - modify trial start / expiration values for AddOnPurchase accordingly.
