test(cloudflare-integration-tests): Type-check test suites in CI (#22068)

mydea · claude · web-flow · commit 616435fcdba8 · 2026-07-08T12:23:43.000+02:00
The `suites/**` files in `cloudflare-integration-tests` were never type-checked in CI: there was no `type-check` script, and vitest transpiles with esbuild (no type-checking). The suites are already covered by `tsconfig.json`, so this adds a gate and fixes the ~30 latent type errors it surfaced. **All fixes are type-only — no runtime behavior changed.** ## Changes - Add a `type-check` script (`tsc --noEmit`) and run `yarn type-check` for the package in the **Lint** CI job. - **Worker fixtures** (`suites/tracing/propagation/**`): drop an incorrect `implements RpcTarget` (Durable Objects expose their public methods over RPC inherently), and let the `WorkerEntrypoint` classes use the ambient `Cloudflare.Env` — which is what `withSentry`'s `WorkerEntrypointConstructor` requires — casting `this.env` to the local `Env` for binding access. (A global `Cloudflare.Env` augmentation would be more idiomatic but collides across fixtures that declare the same binding name with different DO classes into one tsc program.) - **AI assertions** (`google-genai` / `langchain` / `langgraph` test files): type the `span` callback params as `SerializedStreamedSpan`. - Narrow envelope items before accessing `.spans` in the durable-object tests, and fix the runner's `Expected` argument typing. - Targeted, commented casts for version-skewed AI mocks (LangChain callback handler, OpenAI mock client, vercel AI mock language model). - Exclude `suites/prisma/**` from the check — it imports a Prisma-generated client (`./generated`) that only exists after codegen. Part of a small series adding suite type-checking to the integration-test packages (alongside `node-integration-tests` and `bun-integration-tests` #22059). `deno-integration-tests` is intentionally skipped — it's a Deno project (`deno test --no-check`) that `tsc` can't type-check (URL imports, `Deno` globals).
