# test-playable-web-games

End-to-end testing skill for browser games using deterministic fixtures and browser evidence. A green build does not prove the gameplay actually works.

## What it does

The skill maps full player journeys across web games. It structures checks for launch, core controls, combat encounters, inventory progression, and game completion. The review matrix includes desktop inputs, touch screens in both orientations, and reduced motion modes.

Direct state loading replaces repetitive campaign playthroughs. Testers skip the grind. The workflow relies on seeded fixtures, debug routes, or URL query parameters to jump straight into boss battles, tutorial steps, or low-health conditions. Every action requires visible on-screen feedback like UI changes and health adjustments.

Testing runs within repository-approved browser surfaces under local browser restrictions. Reports capture reproduction steps, severity, viewports, and concise bug proof while separating new regressions from baseline issues. After testing, it shuts down idle browser tabs and development servers to keep the machine clean.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill test-playable-web-games -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/test-playable-web-games/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/test-playable-web-games/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill test-playable-web-games -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/test-playable-web-games/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill test-playable-web-games -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/test-playable-web-games/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install MengTo/Skills test-playable-web-games
```

2. **Manually: put the files in place**
- File: `.github/skills/test-playable-web-games/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill test-playable-web-games -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/MengTo/Skills --path agent-skills/game-development/test-playable-web-games
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/test-playable-web-games/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill test-playable-web-games -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- verify browser game mechanics from start to completion
- test touch and keyboard controls across viewports
- jump directly into boss encounters using query parameters
- catch console errors and verify save-load migrations
- record reproducible bug reports with browser evidence

## Example prompts
- Run an end-to-end QA check on our web game controls and save flow across desktop and mobile viewports
- Test the boss encounter transition using a seeded fixture and collect console warnings
- Verify UI updates and player health feedback during low-health combat states

# Test Playable Web Games

Combine deterministic tests with short real playthroughs. Do not treat a green build as gameplay proof.

## Start with a test matrix

Map the player journey: launch, new game, controls, core action, enemy encounter, reward, inventory/progression, save/continue, loss/retry, pause, settings, and completion. Add device variants for desktop keyboard/mouse, touch portrait, touch landscape, and reduced motion.

## Prefer deterministic review states

Create seedable fixtures, debug routes, or query parameters for combat phase, inventory loadout, boss phase, tutorial step, save migration, low health, and error states. Test important transitions directly rather than grinding through the campaign.

## Verify the player experience

Use the repository-approved browser surface and honor local browser restrictions. Confirm screen-visible feedback after each meaningful action: control response, target state, damage/resource state, UI update, and navigation. Inspect console warnings/errors and sample performance only on a representative live scene.

## Report actionable evidence

Record reproduction steps, expected versus actual result, severity, device/viewport, and the shortest useful proof. Separate new regressions from pre-existing baseline issues. After testing, close idle browser pages, dev servers, and benchmarks while leaving active task resources alone.
