# FEATURE-036-D: Acceptance Test Cases — Feature Lanes & Dependencies

**Date:** 02-17-2026  
**Tester:** Spark (automated agent)  
**Environment:** Chrome DevTools MCP, localhost:5858  
**Result:** ✅ ALL PASS (12/12)

---

## Test Setup

1. Created workflow "lane-test" via API
2. Advanced through ideation + requirement stages (mandatory actions → done)
3. Added 3 features via POST /api/workflow/lane-test/features:
   - FEATURE-040 "Login Page" (independent, depends_on: [])
   - FEATURE-041 "Dashboard" (depends on FEATURE-040)
   - FEATURE-042 "Settings" (independent)
4. Set FEATURE-040 actions: feature_refinement=done, technical_design=in_progress
5. Created "no-feat-test" workflow (no features) for fallback test

## Test Results

### TC-01: Feature Lanes Render on Panel Expand
**ACs:** AC-1.1, AC-1.2, AC-1.3, AC-1.5  
**Steps:** Expand "lane-test" workflow panel  
**Expected:** Feature lanes appear with IDs, names, and stage progress dots  
**Result:** ✅ PASS  
- 3 lanes rendered (FEATURE-040, FEATURE-041, FEATURE-042)
- Each lane has: lane-feature-id (monospace), lane-feature-name (bold), lane-stages with arrows
- FEATURE-040: Refinement (✓ done), Tech Design (active), Implement (active/suggested), Testing/Quality/CR (pending)
- FEATURE-041/042: All stages pending
- lanes-container has position: relative

### TC-02: No Lanes Without Features
**ACs:** AC-1.6  
**Steps:** Expand "no-feat-test" workflow (no features)  
**Expected:** Global action buttons render, no feature lanes  
**Result:** ✅ PASS  
- Shows "IDEATION ACTIONS" with Compose Idea, Reference UIUX, etc.
- No feature-lane or lanes-container elements present

### TC-03: Dependency Tags (⛓ needs / ⇉ Parallel)
**ACs:** AC-2.1, AC-2.2  
**Steps:** Check dep-tag badges on feature lanes  
**Expected:** Dependent features show ⛓ needs, independent show ⇉ Parallel  
**Result:** ✅ PASS  
- FEATURE-040: "⇉ Parallel" (dep-tag parallel)
- FEATURE-041: "⛓ needs FEATURE-040" (dep-tag depends)
- FEATURE-042: "⇉ Parallel" (dep-tag parallel)

### TC-04: SVG Dependency Arrows
**ACs:** AC-2.3, AC-2.4, AC-2.5  
**Steps:** Check SVG overlay for curved arrows  
**Expected:** 1 arrow from FEATURE-040 to FEATURE-041  
**Result:** ✅ PASS  
- dep-svg-overlay SVG element present
- 1 dep-arrow-line (dashed Bézier path)
- 1 dep-arrow-head (arrowhead polygon)
- data-depends-on attributes: FEATURE-041 → "FEATURE-040"

### TC-05: Dependencies Toggle
**ACs:** AC-2.6, AC-2.7  
**Steps:** Click dependency toggle button, check hide/show  
**Expected:** deps-hidden class toggles, SVG and tags hidden/shown  
**Result:** ✅ PASS  
- Toggle OFF: lanes-container gets deps-hidden class, toggle loses active class
- Toggle ON: deps-hidden removed, toggle gets active class
- CSS rules hide SVG overlay and dep-tags via opacity: 0

### TC-06: Feature Selector Dropdown Opens
**ACs:** AC-3.1, AC-3.2  
**Steps:** Click "Select Feature to Work On ▼" button  
**Expected:** Dropdown opens with feature list  
**Result:** ✅ PASS  
- Header: "SELECT FEATURE TO WORK ON"
- FEATURE-040: 🔄 icon, "Login Page", "Tech Design", "→ implementation"
- FEATURE-041: ⏳ icon, "Dashboard", "Refinement"
- FEATURE-042: ⏳ icon, "Settings", "Refinement"

### TC-07: Feature Selector Highlights Lane
**ACs:** AC-3.3, AC-3.4  
**Steps:** Select FEATURE-041 from dropdown  
**Expected:** FEATURE-041 lane highlighted, others not  
**Result:** ✅ PASS  
- FEATURE-041 lane gets "highlighted" class
- FEATURE-040 and FEATURE-042 lose "highlighted" class
- Dropdown closes after selection

### TC-08: Independent Feature Action Dispatch
**ACs:** AC-4.1, AC-5.1  
**Steps:** Click "Implement" action on FEATURE-040 (independent)  
**Expected:** Action dispatches immediately, no confirmation modal  
**Result:** ✅ PASS  
- No workflow-modal-overlay appears
- CLI dispatch proceeds (attempts sendCopilotPromptCommandNoEnter)

### TC-09: Dependent Feature Shows Confirmation Modal
**ACs:** AC-4.2, AC-4.3, AC-4.4, AC-4.5, AC-4.6  
**Steps:** Click "Refinement" action on FEATURE-041 (depends on FEATURE-040)  
**Expected:** Dependency warning modal appears  
**Result:** ✅ PASS  
- Modal shows "⚠️ Dependency Warning" heading
- Shows "FEATURE-041 has unfinished dependencies"
- Lists blocker: "FEATURE-040 (implement)"
- Has "Cancel" and "Proceed Anyway" buttons
- Uses custom workflow-modal, NOT native confirm()
- Cancel dismisses modal without action

### TC-10: Completed Action Shows Toast
**ACs:** AC-1.2 (implied)  
**Steps:** Click "Refinement" on FEATURE-040 (already done)  
**Expected:** Toast message indicating already completed  
**Result:** ✅ PASS  
- Toast: "Refinement is already completed for FEATURE-040"

### TC-11: Stage Ribbon Renders Above Lanes
**ACs:** AC-7.1, AC-7.2  
**Steps:** Check DOM order in expanded panel  
**Expected:** Stage ribbon before feature selector before lanes  
**Result:** ✅ PASS  
- Stage ribbon: ✓ Ideation › ✓ Requirement › Implement › 🔒 Validation › 🔒 Feedback
- Feature selector button below ribbon
- Feature lanes below selector

### TC-12: Layout Matches Mockup
**ACs:** AC-6.1, AC-6.2, AC-6.3  
**Steps:** Visual comparison of feature lanes with mockup  
**Expected:** Layout structure and hierarchy match approved mockup  
**Result:** ✅ PASS  
- Lane structure: label (left, 180px) + stages (right) matches mockup
- Feature ID monospace + feature name bold matches mockup
- Stage dots (✓ done, ● active, text pending) match mockup
- Dependency badges (amber ⛓, blue ⇉) match mockup
- SVG arrows (dashed blue) match mockup
- Dark theme colors adapted from mockup light theme
