Neural Connection Symphony - QA Test Plan

Overview

This document outlines the comprehensive testing strategy for the Neural Connection Symphony rework.

Tester: QA Agent Target File: assets/js/neural-symphony.js Preview Server: localhost:8001

1. Performance Testing

1.1 FPS Measurements

| Test Case | Target | Method | |———–|——–|——–| | Idle animation | 60 FPS | performance.now() delta | | With mouse interaction | 60 FPS | performance.now() delta | | Multiple signals active | 55+ FPS | performance.now() delta | | Window resize during animation | No drops | Visual inspection |

1.2 Memory Testing

| Test Case | Target | Method | |———–|——–|——–| | Initial load | < 20MB | Chrome DevTools Memory | | After 5 min continuous | No growth | Heap snapshot comparison | | After 100 hover interactions | Stable | Heap snapshot | | Object cleanup | No leaks | Timeline allocation |

1.3 CPU Usage

| Test Case | Target | Method | |———–|——–|——–| | Idle | < 10% | Chrome Task Manager | | Active interaction | < 30% | Chrome Task Manager | | Background tab | Near 0% | requestAnimationFrame pause |

2. Visual QA

2.1 Animation Quality

Smooth 60fps animations (no jank)
Natural easing curves
No flickering or tearing
Consistent frame timing

2.2 Color Consistency (Flexoki Palette)

| Color | Light Mode | Dark Mode | Usage | |——-|————|———–|——-| | Red | #AF3029 | #D14D41 | Signals | | Orange | #BC5215 | #DA702C | Active neurons | | Cyan | #24837B | #3AA99F | Connections | | Base-800 | #575653 | - | Inactive neurons | | Base-600 | #878681 | #878681 | Captions |

2.3 Responsive Behavior

| Viewport | Width | Expected Behavior | |———-|——-|——————-| | Mobile | < 600px | Full width, centered | | Tablet | 600-991px | Float right, 280px | | Desktop | 992-1199px | Float right, 320px | | Large | 1200px+ | Float right, 350px | | Phone landscape | < 768px | 50% width, max 300px |

2.4 Dark Mode

Colors switch correctly
Canvas background matches theme
Box shadows update appropriately
Transitions are smooth (0.3s)

3. Accessibility Testing

3.1 prefers-reduced-motion

All animations disabled when preference set
Static fallback displays correctly
No CSS transitions active

Canvas has proper ARIA label
Caption is properly associated
No keyboard traps

4. Interaction Testing

4.1 Mouse Events

| Event | Expected Behavior | |——-|——————-| | mousemove | Nearest neuron highlights | | hover (neuron) | Activation + signal fire | | hover (empty area) | No effect | | rapid movement | Smooth tracking | | mouse leave | Graceful deactivation |

4.2 Touch Events

| Event | Expected Behavior | |——-|——————-| | tap | Neuron activation | | touch drag | Signal trails | | multi-touch | Graceful handling |

4.3 Keyboard (if implemented)

| Key | Expected Behavior | |—–|——————-| | Tab | Focus canvas | | Enter/Space | Activate nearest | | Arrow keys | Move focus |

5. Cross-Browser Testing

5.1 Desktop Browsers

| Browser | Version | Tests | |———|———|——-| | Chrome | Latest | Full suite | | Firefox | Latest | Full suite | | Safari | Latest | Full suite | | Edge | Latest | Basic smoke |

5.2 Mobile Browsers

| Browser | Platform | Tests | |———|———-|——-| | Chrome Mobile | Android | Touch, performance | | Safari Mobile | iOS | Touch, performance |

6. Integration Testing

6.1 README.md Context

Canvas renders in correct position
No style conflicts with page CSS
Flexoki variables accessible
Caption styling matches

6.2 Canvas Sizing

Proper DPI scaling (devicePixelRatio)
No blurry rendering
Correct aspect ratio maintenance

6.3 Page Load

No blocking of main content
Graceful initialization
Handles missing canvas element

7. Error Handling

Graceful degradation if WebGL unavailable
Console errors (should be none)
Network resilience (offline mode)
Invalid input handling
