How Adyen's test environment works

Adyen gives every account a test environment that mirrors its unified payments platform. You integrate the same client-side components and server-side APIs you will use in production, then exercise them with documented test cards and the API Explorer, which lets you call any endpoint interactively. Because test and live share one platform model, moving to production is largely a matter of switching credentials and completing verification. Coverage is broad across cards and wallets, though a few local payment methods have thinner test support, and you need an Adyen company account to begin.
