SlideshowPreview 组件此前无测试覆盖。新增测试验证： - 加载态/错误态渲染 - 幻灯片内容渲染 + 计数器 - close/prev/next 按钮 aria-label 匹配 key-echo 模式 - onClose 回调 - next 按钮前进到下一张 - prev 按钮在第一张时禁用 - 解析失败时显示错误 + 重试按钮 Co-authored-by: Cursor <cursor@vectorcontrol.tech>
3 个 shared 组件此前无测试覆盖，新增 15 个测试： - CodeBlock (6 tests): inline vs block 渲染、language label、copy 按钮 aria-label key-echo、clipboard 调用、collapse/expand toggle 长代码 - PageErrorBoundary (3 tests): 正常渲染、catch error 显示 alert+title、 Retry 按钮调用 onReset - DiffReviewPanelParts (6 tests): file tabs 渲染/aria-selected/click、 toolbar stats 渲染、modified count 零值隐藏、accept/reject 回调 AGENTS.md §5 三件套覆盖缺口从 4 降至 0。 Co-authored-by: Cursor <cursor@vectorcontrol.tech>

Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to This test-only PR does not change production behavior, but the new test suite currently contains fixtures that can fail type checking, while several assertions are coupled to implementation details or do not fully verify recovery and state changes. Merge should wait for these fixes and the required repository checks. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

80-90: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAssert the collapsed body state.
This test checks only the button label. It can pass while
styles.codeBodyCollapsedremains unchanged. Assert the body wrapper's collapsed state before and after the click.🤖 Prompt for AI Agents

Keep the existing button-label assertions.
59-78: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAdd the 20/21-line boundary cases.
CodeBlock.tsxcollapses code only when the line count is greater thanCODE_COLLAPSE_LINE_THRESHOLD. The current tests cover one line and 25 lines. Add cases for exactly 20 lines and exactly 21 lines to detect off-by-one regressions.🤖 Prompt for AI Agents

Inline comments:
In `@app/shared/src/ui/CodeBlock.test.tsx`:
- Around line 41-42: Update the CodeBlock tests’ button queries and assertions
to use shared test i18n resources or translated accessible names rather than
repeating the implementation keys code.copy, code.copied, code.expand, and
code.collapse. Apply this consistently to all referenced assertions while
preserving their existing behavior.
Apply the same fix in `@app/shared/src/ui/SlideshowPreview.test.tsx` around lines
107 - 112: The same implementation-string coupling appears across the slideshow
assertions.
In `@app/shared/src/ui/DiffReviewPanelParts.test.tsx`:
- Around line 18-22: Update the mockFiles DiffReviewFile fixtures to include the
required additions and deletions numeric fields for every file entry, using
values appropriate for the test setup.
- Around line 6-10: Remove the vi.mock('./syntaxHighlight', ...) declaration
from the test setup; keep the DiffReviewFileTabs and DiffReviewToolbar tests
unchanged, since they do not depend on highlightLine or
highlightLineWithWordDiff.
Apply the same fix in `@app/shared/src/ui/CodeBlock.test.tsx` at line 15: The same
project-local mocking boundary issue applies to the prismRegistry mock.
In `@app/shared/src/ui/PageErrorBoundary.test.tsx`:
- Around line 32-53: Update the PageErrorBoundary tests to verify observable
behavior: replace the vacuous “Page content” absence check with an h2 heading
assertion, and avoid hard-coding fallback error wording. Make the retry test use
a stateful harness that stops rendering Thrower from onReset, while preserving
the callback assertion, then assert that “Recovered page” renders after retry.
