How to install both an In-Dyno and a Heroku Key-Value Store in Heroku CI?

Issue

I want to install both In-Dyno and Heroku Key-Value Store (KVS) in Heroku CI. In-Dyno Heroku KVS is for tests in a single dyno and Heroku KVS is for queuing for parallel tests.

When I write an app.json below, it appears that only Heroku Redis is installed as REDIS_URL, but an In-Dyno Redis isn't installed.

{
  "environments": {
    "test": {
      "addons": ["heroku-redis:mini", "heroku-redis:in-dyno"]
    }
  }
}

Resolution

You can use as option to name the mini instance's URL. CI_QUEUE_URL is added for the mini Heroku KVS in the following app.json.

"environments": {
  "test": {
    "addons":[
      { "plan": "heroku-redis:mini", "as": "CI_QUEUE" },
      { "plan": "heroku-redis:in-dyno" }
    ]
  }
