charset=UTF-8 Content-Transfer-Encoding: 8bit Three bugs discovered during SDK testing: 1. Refund route didn't parseInt the amount from form-encoded body, causing string concatenation when accumulating partial refunds (e.g. 0 + "2000" = "02000" instead of 2000) 2. Expand params only supported expand[]=field format (curl/raw) but not expand[0]=field (Stripe SDK). Added parseExpandParams() helper that handles both formats, updated all 4 routes that use expansion. 3. No magic token for declined cards — added tok_chargeDeclined which creates a card with last4 "0002" (triggers automatic decline in the payment simulation). Previously, decline testing required the internal actionFlags.failNextPayment mechanism. Added 10 new SDK tests verifying all three fixes work end-to-end. --- src/lib/expand.ts | 19 ++++ src/routes/charges.ts | 4 +- src/routes/invoices.ts | 4 +- src/routes/payment-intents.ts | 4 +- src/routes/refunds.ts | 3 + src/routes/subscriptions.ts | 4 +- src/services/payment-methods.ts | 1 + tests/sdk/e-commerce.test.ts | 184 ++++++++++++++++++++++++++++++++ 8 files changed, 215 insertions(+), 8 deletions(-) diff --git a/src/lib/expand.ts b/src/lib/expand.ts index f6fdb55..798bed6 100644 --- a/src/lib/expand.ts +++ b/src/lib/expand.ts @@ -1,5 +1,24 @@ import type { StrimulatorDB } from "../db"; +/** + * Parse expand params from URL search params. + * Handles both `expand[]=field` (curl/raw) and `expand[0]=field` (Stripe SDK) formats. + */ +export function parseExpandParams(url: URL): string[] { + // Try expand[] format first (curl / raw requests) + const pushFormat = url.searchParams.getAll("expand[]"); + if (pushFormat.length > 0) return pushFormat; + + // Try indexed format: expand[0], expand[1], ...

charset=UTF-8 Content-Transfer-Encoding: 8bit All list endpoints used `gt(created, cursor.created)` for cursor-based pagination, which broke when multiple items shared the same second- precision timestamp — the cursor would skip items or return empty pages. Fix: Added `cursorCondition()` helper that uses a composite cursor: (created > cursor.created) OR (created = cursor.created AND id > cursor.id) Combined with `ORDER BY created, id` on all list queries, this ensures deterministic, gap-free pagination regardless of creation timing. Also fixed: - Events service: was using eq() instead of lt() for desc-ordered cursor - Events service: added secondary desc(id) sort for same-second ordering - Test clocks service: cursor was validated but completely ignored - Webhook endpoints service: cursor was validated but completely ignored --- src/lib/pagination.ts | 20 +++++++++++++++++++ src/services/charges.ts | 16 +++++++-------- src/services/customers.ts | 8 +++++--- src/services/events.ts | 26 +++++++++++++++---------- src/services/invoices.ts | 16 +++++++-------- src/services/payment-intents.ts | 16 +++++++-------- src/services/payment-methods.ts | 16 +++++++-------- src/services/prices.ts | 14 +++++++------ src/services/products.ts | 8 +++++--- src/services/refunds.ts | 16 +++++++-------- src/services/setup-intents.ts | 8 +++++--- src/services/subscriptions.ts | 16 +++++++-------- src/services/test-clocks.ts | 10 ++++++++-- src/services/webhook-endpoints.ts | 8 +++++--- tests/sdk/search-and-pagination.test.ts | 10 +++++++--- 15 files changed, 127 insertions(+), 81 deletions(-) diff --git a/src/lib/pagination.ts b/src/lib/pagination.ts index 0041415..db06ea8 100644 --- a/src/lib/pagination.ts +++ b/src/lib/pagination.ts @@ -1,3 +1,6 @@ +import { gt, eq, and, or } from "drizzle-orm";
