Both TestFlight and Google Play allow developers to configure their app for "test" in-app purchases that don't actually charge the user's credit card. For website payment processes, we recommend using test/fake credit card numbers. If you need participants to complete real purchases, we can help you too - please contact us to discuss your project and arrange a quote.
Most testers are not willing to make purchases, but for small amounts it may be possible to recruit some testers and explain that they will be reimbursed through refunds or through the incentive provided.
You should add these expectations to your Screening Survey so testers can opt in our out based on your expectations.
