# Test mode

> Test your discounts before going live — no subscription required

Test mode lets you try out Discount Kit's discounts on your store before subscribing. Create any discount type, enable test mode, and only customers tagged `test` will see and receive the discount. Your real customers are never affected.

## How it works

1. **Create a discount** — choose any discount type and configure it as you normally would
2. **Enable test mode** — toggle test mode on in the discount settings
3. **Tag a customer** — add the `test` tag to a customer account in your Shopify admin
4. **Log in and test** — log in to your storefront as that customer and verify the discount applies

<Note>
  Test mode discounts require the customer to be **logged in** with the `test` tag. Customers without the tag, and guests who are not logged in, will not see or receive the discount.
</Note>

## No subscription required

Test mode is available on all plans, including before you subscribe. This means you can fully verify that a discount works for your use case before committing to a plan.

Once you're happy with the results, subscribe to a plan and then disable test mode to make the discount live for all eligible customers.

## Tagging a customer for testing

In your Shopify admin:

1. Go to **Customers**
2. Select the customer you want to use for testing
3. In the **Tags** section, add the tag `test`
4. Save the customer

## Storefront visibility

If you're using [Discount Kit Live](/live/introduction) to display discounts on your storefront, test mode discounts are automatically excluded from the `max_reward_percent` and `max_reward_cents` scalar metafields. This means your storefront badges and banners won't show test discounts to regular customers.

If you're working with the full `discounts` array, you can filter test mode discounts using the `test` field. See [filtering test mode discounts](/live/filtering-discounts#filtering-test-mode-discounts) for details.
