async / await: the I/O is the logic
// The call fires immediately, mid-logic. async function registerUser (input) { const found = await db. findUser (input.email); if (found) throw new Error( 'Email in use' ); return db. saveUser (input); } // To test it you must run it. When it fails // in prod, nothing was recorded to replay.
You check behavior by executing it. The failed run leaves no trace you can step through.
