The check-docs failure here is not flaky, it's a genuine type-check break caused by the vitest 4 → 5 major bump. The build of @aws-lambda-powertools/testing-utils fails on packages/testing/src/setupEnv.ts with two errors:

  1. TS2428: All declarations of 'Assertion' must have identical type parameters (line 237)
    vitest 5 changed the Assertion interface from Assertion<T = any> to Assertion<R extends void | Promise<void> = void, T = unknown> (same change for Matchers). Our module augmentation still uses the single-parameter form, so the declaration merge is rejected. This part is ours to fix.

  2. TS2322: toReceiveCommandWith ... is not assignable to type 'RawMatcherFn<MatcherState, any[]>' (line 7)
    vitest 5 no longer depends on a separate @vitest/expect package; the expect types are bundled into vitest itself. However aws-sdk-client-mock-vitest@7.1.0 has a hard dependency on @vitest/expect@^4.1.0, so the lockfile in this PR still installs @vitest/expect@4.1.11 alongside vitest 5. The matchers exported by aws-sdk-client-mock-vitest are typed against the 4.x MatcherState, while expect.extend in vitest 5 expects its own bundled copy, and the two are not assignable to each other.

The second error is upstream: aws-sdk-client-mock-vitest has not released a version compatible with vitest 5 yet (latest is 7.1.0, and there is no open issue or PR for vitest 5 support in https://github.com/stschulte/aws-sdk-client-mock-vitest). We could paper over it with an npm override or a cast, but that would be fragile.

We'll hold this bump until aws-sdk-client-mock-vitest ships vitest 5 support, then update the Assertion augmentation in setupEnv.ts alongside it.

fix(tests): adapt type augmentations to vitest 5
c75ccc4 
vitest 5 changes Assertion<T> to Assertion<R, T> and stops exporting
the Procedure type that a bare vi.fn() infers, so exported mock helpers
need an explicit Mock annotation.

fix(tests): await async assertions and match thrown value
8b17ef2 
vitest 5 fails tests whose .resolves/.rejects assertions are not awaited
and no longer treats a thrown string as equal to an Error with the same
message.

The aws-sdk-client-mock-vitest dependency has been removed and the type error on our side has been fixed. Also had to fix a few issues around async expect statements.
