Generate comprehensive tests for code. Use when user says "write tests for this function", "add unit tests to this file", "generate integration tests for the API", "I need test coverage for this module", or "create e2e tests for the checkout flow".

What this skill does


# Test Generator

Generate comprehensive tests with advanced testing strategies, scenario generation, and edge case identification.

## When to Activate

- User asks to write tests
- User mentions test coverage
- User wants unit, integration, or e2e tests
- After implementing new features (suggest tests)
- User asks about testing a specific file or function

## Quick Process

1. **Analyze Code**: Understand structure and dependencies
2. **Select Strategy**: Choose testing approach based on code type
3. **Generate Tests**: Create tests with appropriate framework
4. **Identify Edge Cases**: Boundary conditions and error handling
5. **Output Files**: Write test files with full coverage

## Options

| Option           | Values                                    | Default     |
| ---------------- | ----------------------------------------- | ----------- |
| `--framework`    | jest, vitest, pytest, cypress, playwright | auto-detect |
| `--type`         | unit, integration, e2e, all               | unit        |
| `--strategy`     | standard, scenario, property, mutation    | standard    |
| `--requirements` | User stories for scenario generation      | (none)      |

## Strategies

- **Standard**: Traditional unit testing with assertions
- **Scenario**: Behavior-driven from user stories (Given-When-Then)
- **Property**: Property-based testing for pure functions
- **Mutation**: Mutation testing to verify test quality

## Edge Case Emphasis

Always identifies:

- Boundary values and null/undefined handling
- Overflow/underflow conditions
- Security edge cases (injection, XSS)
- Concurrency and race conditions

## Delegation

Invoke **test-writer-agent** agent with:

- `paths`: Files to test
- `framework`: Testing framework
- `testType`: Testing strategy
- `requirements`: User stories (if provided)

For complex scenarios, coordinate with **context-loader-agent** and **security-analyzer-agent**.

## Examples

```
"Write tests for src/utils/validator.ts"
"Add integration tests for the API endpoints"
"Generate e2e tests for checkout flow"
"I need property-based tests for this pure function"
```

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
