Dev Frontend Accessibility Testing - Vue.js (Gate 1)
Overview
Ensure all Vue.js frontend components meet WCAG 2.1 AA accessibility standards through automated axe-core scanning, keyboard navigation testing, and focus management validation.
Core principle: Accessibility is not optional. All components MUST be accessible to all users, including those using keyboard navigation, screen readers, and assistive technologies.
CRITICAL: Role Clarification
This skill ORCHESTRATES. Vue.js Frontend QA Analyst Agent (accessibility mode) EXECUTES.
| Who | Responsibility |
|---|---|
| This Skill | Gather requirements, dispatch agent, track iterations |
| QA Analyst Frontend Vue.js Agent | Run axe-core, write keyboard tests, verify ARIA |
Standards Reference
MANDATORY: Load testing-accessibility.md standards via WebFetch.
Step 1: Validate Input
REQUIRED INPUT:
- unit_id: [task/subtask being tested]
- implementation_files: [files from Gate 0]
- language: [typescript only]
OPTIONAL INPUT:
if any REQUIRED input is missing:
→ STOP and report: "Missing required input: [field]"
if language != "typescript":
→ STOP and report: "Vue.js frontend accessibility testing only supported for TypeScript/Vue"
Step 2: Dispatch Vue.js Frontend QA Analyst Agent (Accessibility Mode)
⛔ Agent Name Resolution: MUST resolve bee: names to runtime-qualified names before dispatch. See shared-patterns/shared-orchestrator-principle.md → "Agent Runtime Resolution".

**MODE:** ACCESSIBILITY TESTING (Gate 1)
**Standards:** Load testing-accessibility.md (frontend-vuejs)
**Input:**
- Unit ID: {unit_id}
- Implementation Files: {implementation_files}
- Language: typescript
- Framework: Vue 3 with Composition API
**Requirements:**
1. Run axe-core scans on all Vue components (all states: default, loading, error, empty, disabled)
2. Test keyboard navigation (Tab, Enter, Escape, Arrow keys)
3. Test focus management (trap, restoration, auto-focus) - use Vue's nextTick() where needed
4. Verify semantic HTML usage within Vue templates
5. Check ARIA attributes on dynamic Vue template bindings (v-bind:aria-*, :aria-*)
6. Verify color contrast
7. Test with Vue Testing Library (@testing-library/vue) + axe-core
**Vue-Specific Checks:**
- Teleport components (modals via <Teleport>) have proper focus trapping
- v-show vs v-if usage does not create hidden but focusable elements unexpectedly
- Dynamic :disabled bindings properly prevent interaction
- Transition/animation does not cause focus loss
- defineExpose() patterns for ref-based focus management are correctly implemented
**Output Sections Required:**
- ## Accessibility Testing Summary
- ## Violations Report
- ## Handoff to Next Gate
Step 3: Evaluate Results
Parse agent output:
if "Status: PASS" in output:
→ Gate 1 PASSED
→ Return success with metrics
if "Status: FAIL" in output:
→ Dispatch fix to implementation agent (bee:frontend-engineer-vuejs or bee:ui-engineer-vuejs)
→ Re-run accessibility tests (max 3 iterations)
→ If still failing: ESCALATE to user
Step 4: Generate Output
## Accessibility Testing Summary
**Status:** {PASS|FAIL}
**Components Tested:** {count}
**Violations Found:** {count}
**Keyboard Nav Tests:** {count}
**Focus Management Tests:** {count}
## Violations Report
| Component | States Scanned | Violations | Status |
|-----------|---------------|------------|--------|
| {component} | {states} | {count} | {PASS|FAIL} |
## Handoff to Next Gate
- Ready for Gate 2 (Unit Testing): {YES|NO}
- Iterations: {count}
Anti-Rationalization Table
See shared-patterns/shared-anti-rationalization.md for universal anti-rationalizations. Gate-specific:
| Rationalization | Why It's WRONG | Required Action |
|---|---|---|
| "It's an internal tool" | WCAG compliance is mandatory for all applications. | Run accessibility tests |
| "The library handles it" | Components can be misused. axe-core catches misuse. | Run axe-core scans |
| "We'll fix accessibility later" | Retrofitting costs 10x. Fix now. | Fix violations now |
| "Only one violation, it's minor" | One violation = FAIL. No exceptions. | Fix all violations |
| "Keyboard nav works, I tested manually" | Manual ≠ automated. Tests must be repeatable. | Write automated tests |
| "Vue transitions handle focus automatically" | Transitions do not manage focus. Implement explicitly. | Add focus management tests |
| "v-show hides it visually, accessibility handled" | v-show keeps element in DOM. axe-core still scans it. | Use v-if or add aria-hidden |
