fix(ai-sandbox): compare snapshot transcript by role and content by AlemTuzlak · Pull Request #1168 · TanStack/ai

AlemTuzlak · 2026-08-20T14:39:31Z

After #1126, chat() stores the completed assistant turn with id and createdAt. The portable snapshot test compared the full message object, so @tanstack/ai-sandbox:test:lib failed on main.

This PR compares role and content only. The checkpoint still stores the extra fields.

🎯 Changes

The snapshot lifecycle test no longer requires the assistant message to have only role and content.

No docs update. This is a test assertion, not a user-facing change.
No changeset. Published packages did not change.

✅ Checklist

I have followed the steps in the Contributing guide.
I have tested this code locally with pnpm run test:pr.
Docs: I updated docs/ for this change, or this change is not user-facing.
Changeset: I added a changeset (pnpm changeset), or this PR does not change a published package.

🚀 Release Impact

This change affects published code, and I have generated a changeset.
This change is docs/CI/dev-only (no release).

Testing

Commands run:

pnpm --filter @tanstack/ai-persistence build
pnpm --filter @tanstack/ai-sandbox build
pnpm --filter @tanstack/ai-sandbox test:lib — 971 passed

Skipped pnpm test:pr (full affected CI set). The red job on main is only @tanstack/ai-sandbox:test:lib.

Manual test:

On main, run pnpm --filter @tanstack/ai-sandbox test:lib
See persists the completed transcript, files, and artifacts after completion fail because the assistant message has id and createdAt
On this branch, run the same command
The suite passes

How this PR makes testing easy: the failing unit test is the coverage. No extra command or example app change.

Risk / rollback

Low. One assertion. Revert the PR to undo.

Summary by CodeRabbit

Tests
- Improved snapshot lifecycle validation by focusing transcript comparisons on message roles and content.
- Reduced test brittleness from unrelated message metadata changes.

After persist-structured-output, chat stores assistant id and createdAt on the completed turn. The portable snapshot test compared the full message object, so main failed. Compare role and content only.

Merge Risk: ⚪ Minimal · up to f6e95

This change only narrows the snapshot assertion to the assistant message role and content while preserving checkpoint fields; it does not alter published or runtime behavior, and no actionable merge-blocking risk remains.
