## What it does

The skill handles the testing side of an Adobe App Builder project. It reads your action and UI component sources, works out which SDKs they touch, then picks the right template: a unit test, an integration test against a deployed action, a contract test for Adobe API calls, or a React component test built on Testing Library. Clear requests skip the full scan — name the test type and it generates straight away.

What ships inside: `assets/unit-test-template.js`, `assets/integration-test-template.js`, `assets/component-test-template.js`, plus mock helpers for the State, Files, Events and Database SDKs, `@adobe/aio-lib-*` clients, ExC Shell context (`@adobe/exc-app`) and UIX Guest SDK (`@adobe/uix-guest`). Components get wrapped in `<Provider theme={defaultTheme}>`, since Spectrum renders nothing without it. Tests live in `test/` mirroring the action path, and you run them with `aio app test` or `npx jest --coverage`.

It expects `aio` CLI, Node.js 18+ and Jest. A project on a different test runner or an unusual directory layout means editing the templates by hand — worth checking your config before you generate anything.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add adobe/skills --skill appbuilder-testing -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add adobe/skills --skill appbuilder-testing -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add adobe/skills --skill appbuilder-testing -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install adobe/skills appbuilder-testing
```

2. **Manually: put the files in place**
- File: `.github/skills/appbuilder-testing/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add adobe/skills --skill appbuilder-testing -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/adobe/skills --path plugins/app-builder/skills/appbuilder-testing
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add adobe/skills --skill appbuilder-testing -a opencode
```

### Claude.ai

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

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/adobe/skills/tree/HEAD/plugins/app-builder/skills/appbuilder-testing/SKILL.md

## When to use it
- write unit tests for a Runtime action
- mock the State, Files or Events SDK in a test
- verify a deployed action with an integration test
- test a React component with Provider and ARIA selectors
- debug a failing Jest run in an App Builder project

## Example prompts
- Write unit tests for my action
- My action uses the State SDK — help me mock it in tests
- Run the tests and show me coverage

# App Builder Testing

Generate and run Jest tests for Adobe App Builder actions and React Spectrum UI components. Scaffolds unit tests, integration tests, component tests, and mock helpers for Adobe SDKs.

## Pattern Quick-Reference

Pick the template or reference that matches the user's intent. Default to `assets/unit-test-template.js` for generic test requests.

| User wants | Reference | Template / Asset |
| --- | --- | --- |
| Unit test for an existing action | references/testing-patterns.md | assets/unit-test-template.js |
| Integration test against deployed action | references/testing-patterns.md | assets/integration-test-template.js |
| Component test for React Spectrum UI | references/component-testing-patterns.md | assets/component-test-template.js |
| Mock ExC Shell context in tests | references/component-testing-patterns.md | assets/shell-mock-helper.js |
| Mock AEM extension context in tests | references/component-testing-patterns.md | assets/uix-guest-mock-helper.js |
| Mock State SDK in tests | references/mock-catalog.md | assets/mock-state-sdk.js |
| Mock Files SDK in tests | references/mock-catalog.md | assets/mock-files-sdk.js |
| Mock Events SDK in tests | references/mock-catalog.md | assets/mock-events-sdk.js |
| Mock Database SDK in tests | references/mock-catalog.md | assets/mock-database-sdk.js |
| Full mock catalog (all SDKs) | references/mock-catalog.md | — |
