How to enable Test Mode in Billing using Graphql?

[tyuzu]

Hello I'm building Billing plans for my App. But I can't test it since the created charge is not for for test which I can't proceed on confirmationUrl since it needs real credit card.

Already added test: true on the variable but still it return test: false on response.

// Request GrapQL
const response: Response = await admin.graphql(
    `#graphql
    mutation AppSubscriptionCreate($name: String!, $lineItems: [AppSubscriptionLineItemInput!]!, $returnUrl: URL!) {
        appSubscriptionCreate(name: $name, returnUrl: $returnUrl, lineItems: $lineItems) {
          userErrors {
            field
            message
          }
          appSubscription {
            id
            name
            status
            test
          }
          confirmationUrl
        }
    }`,
    {
        variables: {
            "name": "Super Duper Recurring Plan",
            "returnUrl": "http://super-duper.shopifyapps.com/",
            "lineItems": [
              {
                "plan": {
                  "appRecurringPricingDetails": {
                    "price": {
                      "amount": 10,
                      "currencyCode": "USD"
                    },
                    "interval": "EVERY_30_DAYS"
                  }
                }
              },
            ],
            "test": true
          }
          ,
    }
);

const responseJson = await response.json();

return responseJson;

mutation error test was not defined. Sorry, I just realized now.

    mutation AppSubscriptionCreate($name: String!, $lineItems: [AppSubscriptionLineItemInput!]!, $returnUrl: URL!) {
        appSubscriptionCreate(name: $name, returnUrl: $returnUrl, lineItems: $lineItems) {
