Before offering your loyalty program in your store, it may be worthwhile to check and see if everything is working as you intended it to.
After you have defined the activity rules and reward algorithms, you can convert those points and test it in your store.
To do this, follow the steps outlined below:
Create an account on your store (if an activity rule is set for account creation, test it out here).
Enable Shopify Payments (test mode) if you do not want to use a real payment method

Once the purchase is redeemed, see if you are getting the points for the purchase, and that you are receiving the amount of points you have defined.
Make however many test purchases are necessary to accrue enough points to redeem a reward you have defined.
Check to see if the points to reward ratio is correct.
If everything looks the way that you intended, you are good to go!
