Example_queryWithExprMul verifies the new structured-expression aggregate path: SUM(id * 2) over the seeded products table (id = 1..100, so the sum is 2 * 5050 = 10100). Exercises arithmetic with a column ref and a numeric literal — the most common metric pattern (revenue, line totals).

Example_queryWithOpenAPIJoin exercises the full OpenAPI integration against a real GraphJin engine, end-to-end:

• A temp OpenAPI 3 spec is dropped in a tempdir.
• The mock upstream verifies that bearer auth was applied — if the header is missing the server panics, failing the test loudly.
• A GraphJin Config carries an openapi source with credentials and join wiring.
• The resulting GraphQL query joins the upstream's response onto the parent users table via the synthesised "openapi" resolver type.

This test runs against every dialect the harness is configured for (postgres, mysql, mariadb, sqlite, oracle, mssql, snowflake, mongodb) because the dialect-specific work — parent SQL emission with the remote-marker placeholder column — flows through the same code path as remote_api, which already has dialect coverage. The OpenAPI sub- package itself is dialect-independent, so one engine-level test gives us proof the wiring works without N copies for N dialects.

// Spin up a mock upstream that mimics a single-record lookup
// (GET /payments/{paymentId} returning {data: {desc, amount}}). The
// shape mirrors what Salesforce MC Personalization, Stripe-style
// services, and most CRUD-y REST APIs publish, so the test exercises
// the realistic case rather than a contrived one.

Example_queryWithOpenAPITopLevel exercises a top-level OpenAPI virtual table — no parent DB row, args coming from the GraphQL field itself.

Spec: GET /audit-logs?actorId=… returning {data: [{id, action}, ...]}. Query: { audit_logs(actorId: "u-7") { id action } }.

The mock upstream verifies both bearer auth and that the actorId query parameter was forwarded. End-to-end this exercises the full pipeline: classifier → registry → bridge → pre-registered synthetic table → qcode RelRemote marking → gstate all-remote skip → remote_join parent-less branch → caller HTTP roundtrip → result-path strip → field filter → response.
