A failed payment at checkout is one of the fastest ways to lose a sale — and a customer’s trust.

The good news: with Easy Digital Downloads (EDD) and Stripe, you can run a complete test in minutes. No real charges, no risk. Just a safe simulation that lets you catch problems before your customers do.

Why Test Stripe Payments Before Going Live?
Conducting tests helps you identify and address issues before they affect your customers’ checkout experience.
By testing Stripe payments, you can:
- Confirm customers can complete transactions without errors or payment failures
- Verify that payments are processed correctly and sales are recorded in EDD
- Prevent cart abandonment caused by checkout issues
- Identify misconfigurations or plugin conflicts before they cost you real sales
- Know exactly what your customers see when a payment succeeds (or fails)
Whether Stripe is your only payment gateway or one of many, testing before going live saves you from a lot of preventable problems. With the right eCommerce plugin, the whole process takes just a few steps.
How to Test Stripe Payments in WordPress
This guide assumes you already have Easy Digital Downloads installed and Stripe connected to your site.
Not set up yet? See our guide on setting up Stripe first, then come back here to test.
Step 1: Enable Test Mode
Go to Downloads » Settings » Payments. Check the box next to Enable Test Mode and click Save Changes.
When test mode is active, no real payments are processed. You can run as many test transactions as you need without any actual charges.
Your Stripe connection and gateway settings stay exactly as they are. You’re just switching on a safe testing environment.
Step 2: Run a Test Transaction
Visit your store from the front end and add a product to your cart.
If you don’t have a product set up yet, go to Downloads » Add Download to create one first. See our guide on Creating Products or how to sell digital products in WordPress for a full walkthrough.
Proceed to the checkout page and fill in your billing details. In the Payment Info section, select Stripe as your payment method. You’ll see exactly how your checkout appears to customers, including the payment options they can choose from.
Use Stripe’s basic success test card to simulate a completed payment:
- Card number: 4242 4242 4242 4242
- Expiration date: Any future date
- CVC: Any three-digit number
Click Purchase. A successful test brings you to the purchase confirmation page:
Step 3: Try These Additional Test Card Scenarios
A successful payment is a good start, but it’s not the only scenario worth checking. Your customers will occasionally have cards declined, hit authentication challenges, or run into card limits. You want to know what they see before it happens for real.
Here are four scenarios to run before going live:
| Scenario | Card Number | Expected Result |
|---|---|---|
| Successful payment | 4242 4242 4242 4242 | Payment completes, purchase confirmation shown |
| Generic decline | 4000 0000 0000 0002 | Payment declined, error message shown to customer |
| Insufficient funds | 4000 0000 0000 9995 | Payment declined with insufficient funds message |
| 3D Secure required | 4000 0025 0000 3155 | Authentication modal appears before payment can complete |
Use any future expiration date and any three-digit CVC for all test cards. For the full list, including specific decline codes, dispute scenarios, and international cards, see Stripe’s test cards documentation.
Step 4: Verify Results and Go Live
Log into your Stripe Dashboard and enable the Test mode toggle. Check under Payments; your test charges should be listed there. This confirms the transactions are flowing through correctly and being recorded in Stripe.
When you’re satisfied everything is working correctly, go back to Downloads » Settings » Payments, uncheck Enable Test Mode, and click Save Changes. Your Stripe connection and all settings stay in place. Your store is ready to accept real payments.
💡 Already live? If your store is already accepting real orders, run your tests on a staging site first so customers don’t see test mode during checkout.
FAQs About Testing Stripe Payments in WordPress
Let’s wrap up by answering some common questions people have about Stripe test payments.
Can I use real credit cards for testing Stripe payments?
No. Never use a real card for testing. Stripe provides test card numbers specifically for this purpose, and test mode only accepts those test numbers — real cards won’t work in test mode. If you accidentally run a real card through a live checkout, it will be charged.
How can I access my Stripe API keys?
Log in to your Stripe account, go to the Developers section, and select API keys. You’ll find both your publishable and secret keys there. In EDD, these are managed automatically when you connect via the Connect with Stripe button — you typically don’t need to enter them manually.
What should I do if a test transaction fails?
First, confirm that test mode is enabled in EDD under Downloads » Settings » Payments and that your Stripe account shows as connected. Make sure you’re using a valid Stripe test card number; real card numbers won’t work in test mode. If the issue persists, check for conflicting plugins or refer to our Stripe documentation.
Can I switch from test mode to live mode without reconfiguring everything?
Yes, it’s a single toggle. Go to Downloads » Settings » Payments, uncheck Enable Test Mode, and click Save Changes. Your Stripe connection, active gateways, and payment method settings all stay exactly as they are. No API key swap needed.
How frequently should I test Stripe payments?
Test any time you make significant changes to your store: updating EDD, switching themes, adding new payment methods, or changing checkout settings. A quick test transaction after any major update takes a few minutes and is far faster than troubleshooting a broken checkout after the fact.
Does EDD support other payment gateways besides Stripe?
Yes. Easy Digital Downloads supports several payment gateways including Stripe, PayPal, Square, Authorize.net, and more. For a full comparison, see our guide to the 5 best WordPress payment gateways for eCommerce.
