To test Stripe checkout flows and 3DS challenges without real cards, you use PSP sandbox mode with test-mode credentials and specific test cards. Playwright automates the nested iframe interactions required for SCA challenges to validate success and decline paths safely.

To simulate subscription renewals and failed recurring charges in Stripe, you use server-side test clocks. Test clocks allow you to advance billing time on demand, reproducing recurring billing scenarios and refund flows without waiting for real time to pass.

Yes, you can apply the same payment testing pattern to Adyen, PayPal, and Braintree sandboxes. You swap in each provider's specific sandbox cards, buyer accounts, and notification models while maintaining the same end-to-end Playwright automation structure.

Playwright tests fail handling 3DS iframe challenges in a sandbox due to improper nested iframe handling. The testing process requires specific Playwright configurations to interact with elements inside the nested PSP challenge iframes to complete the SCA flow.

The best way to test payment declines and insufficient funds in a checkout flow is by using designated sandbox test cards provided by the PSP. The Skill validates these specific failure paths end-to-end against the sandbox environment without touching live payment keys.
