11-11: LGTM! Test script properly configured.The test script correctly invokes Vitest and aligns with the new testing infrastructure added in this PR.
24-25: Inconsistent with PR objectives: 3D rendering dependencies added.The PR title "Codex/replace broad matcher in home.test.tsx" suggests a focused change to test matchers, but this adds 3D rendering libraries (
@react-three/drei,@react-three/fiber,zustand) that are unrelated to testing. These additions suggest broader scope changes not mentioned in the PR description.Can you clarify:
- Are these 3D rendering dependencies required for the test changes?
- Should these be in a separate PR with appropriate documentation?
Also applies to: 32-32
35-38: All added testing dependencies have no known vulnerabilities. No advisories found for @playwright/test, @testing-library/jest-dom, @testing-library/react, or @vitejs/plugin-react.frontend/src/test/setupTests.ts (2)
1-1: LGTM! Correct Vitest entrypoint used.The import correctly uses
@testing-library/jest-dom/vitestwhich registers matchers for Vitest'sexpectfunction. This aligns with the library's best practices for Vitest integration.Based on learnings.
3-14: LGTM! Safe and complete matchMedia mock.The implementation properly guards against environments lacking
window.matchMediaand provides a complete, type-safe MediaQueryList stub. All required properties and methods are present, preventing runtime errors in tests.frontend/vitest.config.ts (2)
1-13: LGTM! Standard Vitest configuration for React testing.The configuration correctly sets up:
- React plugin for JSX transformation and Fast Refresh
- jsdom environment for DOM testing (appropriate for React components)
- Global test functions (describe/it/expect)
- Setup file integration for jest-dom matchers and mocks
- Test file discovery pattern matching the actual test location
This aligns with Vitest and React Testing Library best practices.
Based on learnings.
10-11: Verify test discovery pattern: exclude may conflict with future test locations.The
exclude: ['tests/**/*']pattern will prevent discovery of any tests placed in a top-leveltests/directory, whileincludeonly searches undersrc/. This is likely intentional (keeping tests colocated with source code), but ensure this matches your team's testing conventions.If tests might be placed in
tests/in the future, consider either:
- Removing the exclude pattern (Vitest's default excludes are usually sufficient)
- Documenting that tests must live under

🧹 Nitpick | 🔵 Trivial
🧩 Analysis chain
Critical inconsistency: PR title claims "replace broad matcher" but this adds NEW broad regex matchers.
This test file is newly created (not replacing existing code), yet the PR title states "replace broad matcher in home.test.tsx". Additionally, the test uses case-insensitive regex patterns (/AI Engineering MVP Template/i and /A starter template.../i) which are inherently broad matchers that:
- Match case-insensitively
- Match partial text (regex without anchors)
- Could match unintended text
If the goal is to replace broad matchers with precise assertions, consider using exact string matches:
- expect(
- screen.getByRole('heading', { name: /AI Engineering MVP Template/i })
- ).toBeInTheDocument()
+ expect(
+ screen.getByRole('heading', { name: 'AI Engineering MVP Template' })
+ ).toBeInTheDocument()
- expect(
- screen.getByText(
- /A starter template for building AI-powered applications with Vector Institute branding\./i
- )
- ).toBeInTheDocument()
+ expect(
+ screen.getByText(
+ 'A starter template for building AI-powered applications with Vector Institute branding.'
+ )
+ ).toBeInTheDocument()Verification needed:
- What existing test or matcher is being replaced? (None visible in the PR)
- Do these exact strings exist in the Hero component?
Run this script to verify the actual text content in the Hero component:
🏁 Script executed:
#!/bin/bash
# Find and examine the Hero component to verify exact text matches
echo "=== Searching for Hero component definition ==="
fd -e tsx -e ts Hero --exec rg -l "export.*Hero"
echo -e "\n=== Examining Hero component content ==="
fd -e tsx -e ts Hero --exec cat {}
echo -e "\n=== Searching for the heading text in codebase ==="
rg -i "AI Engineering MVP Template" --type-add 'web:*.{tsx,jsx,ts,js}' --type web
echo -e "\n=== Searching for the description text in codebase ==="
rg -i "starter template for building AI-powered applications" --type-add 'web:*.{tsx,jsx,ts,js}' --type webLength of output: 669
Update PR title and use exact string matchers in home.test.tsx
- The PR title claims replacing broad matchers but adds a new test; update it to reflect adding tests.
- Replace broad regex matchers in home.test.tsx with exact string assertions for the heading and description.
🤖 Prompt for AI Agents
In frontend/src/app/__tests__/home.test.tsx lines 1-20, update the PR title to
reflect that a new test was added rather than replacing broad matchers, and in
the test replace the broad regex matchers with exact string matchers: use
getByRole('heading', { name: 'AI Engineering MVP Template' }) and getByText('A
starter template for building AI-powered applications with Vector Institute
branding.') (case-exact as in the source) so the assertions match exact strings
rather than regexes.
