# Testing discounts - Discountline 1.x documentation

> Try your rules on a made-up cart and customer, and see why each rule applies or doesn't.

> [!NOTE]
> This is part of **Discountline Pro**.

**Marketing → Test discounts** runs your published rules on a cart you make up, for a customer you describe. Nothing is saved, and no real cart changes, so it's safe on a live store.

## Run a test

1. **Cart**: search for products (or variations) and set quantities. **Add product** for more lines.
2. **Customer**:
   - **Role**: a guest, or any user role.
   - **Order history**: a first order, or a returning customer who has spent a given amount.
   - **Ships to**: the shipping country.
   - **Payment method**, or "Not chosen yet".
   - **Coupons**: tick if the customer uses one of your coupons.
   - **Date and time**: try a sale before it starts, a happy hour, or a weekend.
3. Click **Test discounts**.

## The result

- **Each line**: the price, the discounted price and the rule that gives it.
- **The totals**: the items subtotal, each order discount and buy X, get Y by name, whether shipping is free, and the total before shipping and tax.
- **Rules that didn't apply**, each with the reason, for example:
  - "Not for this customer role."
  - "Matching items total $54.00; it needs $100.00."
  - "The quantity is below its first tier (5)."
  - "Needs 3 matching items for a full set."
  - "Another rule gives a lower price."
  - "Hasn't started yet."

Shipping rates and taxes depend on the real checkout, so they aren't calculated here. Only published rules are tested. To try a rule before customers see it, give it a start date in the future and test with that date and time.
