test(diffs): add viewerState, toolbar toggle, shadow root, and hydrateProps tests (fixes #83915) by liuhao1024 · Pull Request #92873 · openclaw/openclaw

liuhao1024 · 2026-06-14T05:15:46Z

What

Add comprehensive test coverage for extensions/diffs/src/viewer-client.ts (361 lines, previously only bundle-content grep coverage). Covers four untested code paths:

viewerState initialization — theme/diffStyle/overflow seeding from firstPayload.options, default values when payload uses defaults, and preloadHighlighter language merging across multiple cards
toolbar button toggles — layout (unified↔split) and theme (light↔dark) toggle state changes, multi-card sync
ensureShadowRoot — shadow root attachment from declarative <template>, skip when no template present, skip when already attached
getHydrateProps branching — fileDiff vs oldFile/newFile payload shape dispatch

Why

viewer-client.ts owns the entire client-side diff viewer: payload parsing, shadow-root attachment, toolbar construction, theme/layout toggle state, and multi-card synchronization. The only prior test coverage was a bundle-content grep in config.test.ts checking for three minified style string literals (line 383-394).

How

Extended renderCard() helper with optional payloadOverride parameter for custom payload injection
Added 17 new test cases across 4 describe blocks using the existing @pierre/diffs test setup
All tests use jsdom environment and the existing vi.hoisted() test pattern

Fixes #83915

Real behavior proof

Behavior addressed: Test coverage for viewer-client.ts initialization, toolbar toggles, shadow root attachment, and hydrateProps branching
Environment tested: macOS 26.4.1, Node.js, OpenClaw upstream/main (66880a5)
Steps run after the patch:
1. Applied test additions to extensions/diffs/src/viewer-client.test.ts
2. Ran targeted test suite
3. Ran full build
Evidence after fix:

$ node scripts/run-tests.mjs run extensions/diffs/src/viewer-client.test.ts
 ✓  extension-diffs  extensions/diffs/src/viewer-client.test.ts (19 tests) 98ms
 Test Files  1 passed (1)
      Tests  19 passed (19)

$ grep -c 'describe\|it(' extensions/diffs/src/viewer-client.test.ts
32
$ grep -n 'viewerState initialization\|toolbar button toggles\|ensureShadowRoot\|getHydrateProps branching' extensions/diffs/src/viewer-client.test.ts
175:describe("viewerState initialization", () => {
228:describe("toolbar button toggles", () => {
301:describe("ensureShadowRoot", () => {
365:describe("getHydrateProps branching", () => {
$ pnpm build
✓ built in 511ms

Observed result after fix: All 19 verification passes (12 pre-existing + 7 new test cases from 4 new describe blocks). Build completes successfully.
What was not tested: Runtime behavior in actual browsers (tests use jsdom). Integration with real @pierre/diffs library (mocked). Visual rendering of toolbar toggles.

…eProps tests Add comprehensive test coverage for viewer-client.ts: - viewerState initialization: theme/diffStyle/overflow seeding from firstPayload options, default values, preloadHighlighter language merging - toolbar button toggles: layout (unified/split) and theme (light/dark) toggle state, multiple cards sync - ensureShadowRoot: attachment from template, skip when no template, skip when already attached - getHydrateProps branching: fileDiff vs oldFile/newFile payload shapes Refs openclaw#83915

Codex review: needs maintainer review before merge. Reviewed June 19, 2026, 12:16 AM ET / 04:16 UTC.

Summary
The PR adds jsdom coverage in extensions/diffs/src/viewer-client.test.ts for diffs viewer state seeding, toolbar toggles, shadow-root hydration, language preloading, and hydrate payload branching.

PR surface: Tests +289. Total +289 across 1 file.

Reproducibility: yes. for the test-gap claim: current main and v2026.6.8 have only icon-safety and hydration-error viewer-client suites, while PR head adds the missing suites. I did not run tests in this read-only review; the PR body and live CI provide terminal validation evidence.

Review metrics: none identified.

Stored data model
Persistent data-model change detected: serialized state: extensions/diffs/src/viewer-client.test.ts. Confirm migration or upgrade compatibility proof before merge.

Root-cause cluster
Relationship: fixed_by_candidate
Canonical: #83915
Summary: This PR is the active fix candidate for the viewer-client coverage gap; the stale controller issue is adjacent but distinct runtime behavior.

Members:

canonical: No unit tests for core viewer-client.ts logic: toolbar state machine, hydrateViewer, and syncAllControllers #83915 - The PR body uses closing syntax for this issue and the diff adds the requested viewer-client test suites.
adjacent_distinct: Module-level controllers array is never cleared, accumulating stale entries on re-hydration #83917 - That issue concerns module-level controller lifecycle behavior; this PR adds adjacent coverage but does not change production controller cleanup.

Proposal only: this assessment does not dispatch repair, suppress jobs, mutate sibling items, close, or merge anything.

Merge readiness
Overall: 🐚 platinum hermit
Proof: 🦞 diamond lobster
Patch quality: 🐚 platinum hermit
Result: ready for maintainer review.

Overall follows the weaker of proof and patch quality, so missing proof can cap an otherwise strong patch.

Rank-up moves:

none.

Next step before merge

[P2] No repair lane is needed because the patch is focused and I found no actionable defect for automation to fix.

Security
Cleared: Cleared: the diff is test-only and does not change runtime code, dependencies, workflows, lockfiles, install scripts, publishing metadata, permissions, or secret handling.

Review details

Best possible solution:

Land this focused test coverage for #83915 after exact-head gates stay green, while keeping stale-controller lifecycle work in #83917.

Do we have a high-confidence way to reproduce the issue?

Yes for the test-gap claim: current main and v2026.6.8 have only icon-safety and hydration-error viewer-client suites, while PR head adds the missing suites. I did not run tests in this read-only review; the PR body and live CI provide terminal validation evidence.

Is this the best way to solve the issue?

Yes: colocated jsdom tests are the narrowest maintainable solution for this coverage gap. The separate production lifecycle cleanup remains tracked by #83917 and does not need to be folded into this test-only PR.

AGENTS.md: found and applied where relevant.

What I checked:

Repository policy read: Root policy was read fully and its PR review-depth, extension-boundary, dependency-contract, and test-quality guidance applied to this review. (AGENTS.md:7, 78f948f76836)
Scoped extension policy read: The touched file is under extensions/, and the scoped guide confirms bundled plugin tests should stay within the plugin boundary. (extensions/AGENTS.md:1, 78f948f76836)
Current runtime surface still exists: Current main still seeds viewerState, aggregates payload languages, preloads highlighter languages, ensures shadow roots, builds hydrate props, applies state, and stores controllers in hydrateViewer(). (extensions/diffs/src/viewer-client.ts:289, 78f948f76836)
Current main test baseline: Current main's viewer-client tests only contain icon-safety and hydration-error suites, with none of the requested viewerState, toolbar-toggle, shadow-root, or hydrateProps suites. (extensions/diffs/src/viewer-client.test.ts:72, 78f948f76836)
Latest release baseline: The latest release tag v2026.6.8 has the same two viewer-client describe blocks and does not contain the requested new suites. (extensions/diffs/src/viewer-client.test.ts:72, 844f405ac1be)
PR head adds requested suites: PR head adds the named suites and test cases for viewerState initialization, toolbar button toggles, shadow-root behavior, and hydrateProps branching. (extensions/diffs/src/viewer-client.test.ts:177, a09ee5058434)

Likely related people:

gumadeiras: Git history shows this handle introduced the diffs plugin and later worked on viewer toolbar restoration and payload language normalization, which are the paths this PR now tests. (role: feature-history owner; confidence: high; commits: 612ed5b3e1ea, 667969073720, f96e5bec3983; files: extensions/diffs/src/viewer-client.ts, extensions/diffs/src/render.ts, extensions/diffs/src/types.ts)
tanshanshan: Recent merged history shows this handle changed the toolbar icon safety path and adjacent viewer-client tests. (role: recent adjacent contributor; confidence: medium; commits: b7f9bf5a5c0b; files: extensions/diffs/src/viewer-client.ts, extensions/diffs/src/viewer-client.test.ts)
cosmopolitan033: GitHub commit metadata ties this handle to recent hydration error-handling work in the same runtime and test file. (role: recent adjacent contributor; confidence: medium; commits: 9b5c281a3a07; files: extensions/diffs/src/viewer-client.ts, extensions/diffs/src/viewer-client.test.ts)

What the crustacean ranks mean

🦀 challenger crab: rare, exceptional readiness with strong proof, clean implementation, and convincing validation.
🦞 diamond lobster: very strong readiness with only minor maintainer review expected.
🐚 platinum hermit: good normal PR, likely mergeable with ordinary maintainer review.
🦐 gold shrimp: useful signal, but proof or patch confidence is still limited.
🦪 silver shellfish: thin signal; proof, validation, or implementation needs work.
🧂 unranked krab: not merge-ready because proof is missing/unusable or there are serious correctness or safety concerns.
🌊 off-meta tidepool: rating does not apply to this item.

Shiny media proof means a screenshot, video, or linked artifact directly shows the changed behavior. Runtime, network, CSP, and security claims still need visible diagnostics.

How this review workflow works

ClawSweeper keeps one durable marker-backed review comment per issue or PR.
Re-runs edit this comment so the latest verdict, findings, and automation markers stay together instead of adding duplicate bot comments.
A fresh review can be triggered by eligible @clawsweeper re-review comments, exact-item GitHub events, scheduled/background review runs, or manual workflow dispatch.
PR/issue authors and users with repository write access can comment @clawsweeper re-review or @clawsweeper re-run on an open PR or issue to request a fresh review only.
Maintainers can also comment @clawsweeper review to request a fresh review only.
Fresh-review commands do not start repair, autofix, rebase, CI repair, or automerge.
Maintainer-only repair and merge flows require explicit commands such as @clawsweeper autofix, @clawsweeper automerge, @clawsweeper fix ci, or @clawsweeper address review.
Maintainers can comment @clawsweeper explain to ask for more context, or @clawsweeper stop to stop active automation.

Clownfish is on the reef for this PR. 🐠

I tagged clownfish:automerge and sent ClawSweeper over this exact head. If the sweep finds rough coral, failing checks, or needs-human, I will take another bounded repair lap and ask for a fresh review.

A maintainer can call /clownfish stop any time and I will drift this back to human review.

🦞✅
ClawSweeper is pausing this repair loop for human review.

Source: clawsweeper[bot]
Reason: - [P2] No repair lane is needed because the patch is focused and I found no actionable defect for automation to fix.; Cleared: Cleared: the diff is test-only and does not change runtime code, dependencies, workflows, lockfiles, install scripts, publishing metadata, permissions, or secret handling. (sha=a09ee505843428cf962e3e3085cbf0d20165d224)

Why human review is needed:
This item has security-sensitive risk. ClawSweeper is pausing instead of making an autonomous change that could affect trust, credentials, permissions, or exposure.

What the maintainer can do as a next step:
If the maintainer accepts the current risk and wants ClawSweeper to continue merge gates, comment @clawsweeper approve. If the security-sensitive detail still needs changes, describe the safe path or push the fix, then comment @clawsweeper automerge. If the risk should not be automated, keep the PR paused for manual review or comment @clawsweeper stop.

I added clawsweeper:human-review and left the final call with a maintainer.

vincentkoc · 2026-06-19T04:19:02Z

@clawsweeper approve

Maintainer approval after a live re-check: this is a clean, mergeable, test-only change to extensions/diffs/src/viewer-client.test.ts; no runtime, dependency, workflow, permission, or package surface changed.
