Let’s assume you are using a popular open-source emulator (e.g., lnd-emulator from GitHub or litd 's embedded mode). Here’s a typical workflow. The emulator will store this invoice in memory

Want to see how your app behaves when LND responds with UNKNOWN_PAYMENT_HASH ? The emulator can inject failures at a rate you specify—something dangerous to do on testnet.
