summary

Run tests for React codebase across multiple release channels and configurations.

›Supports six release channels: source (default), experimental, www, www with variant false, stable, and classic, each with distinct feature flag configurations
›Accepts test patterns, watch mode for TDD, and variant flags to test different code paths
›Requires explicit test pattern argument to avoid running the entire test suite; uses --silent flag to surface failures and --no-watchman for sandboxing comp

skill.md

Run tests for the React codebase.

Arguments:

$ARGUMENTS: Channel, flags, and test pattern

Usage Examples:

/test ReactFiberHooks - Run with source channel (default)
/test experimental ReactFiberHooks - Run with experimental channel
/test www ReactFiberHooks - Run with www-modern channel
/test www variant false ReactFiberHooks - Test VARIANT=false
/test stable ReactFiberHooks - Run with stable channel
/test classic ReactFiberHooks - Run with www-classic channel
/test watch ReactFiberHooks - Run in watch mode (TDD)

Release Channels:

(default) - Source/canary channel, uses ReactFeatureFlags.js defaults
experimental - Source/experimental channel with EXPERIMENTAL flags = true
www - www-modern channel with VARIANT flags = true
www variant false - www channel with VARIANT flags = false
stable - What ships to npm
classic - Legacy www-classic (rarely needed)

Instructions:

Parse channel from arguments (default: source)
Map to yarn command:
- (default) → yarn test --silent --no-watchman <pattern>
- experimental → yarn test -r=experimental --silent --no-watchman <pattern>
- stable → yarn test-stable --silent --no-watchman <pattern>
- classic → yarn test-classic --silent --no-watchman <pattern>
- www → yarn test-www --silent --no-watchman <pattern>
- www variant false → yarn test-www --variant=false --silent --no-watchman <pattern>
Report test results and any failures

Hard Rules:

Use --silent to see failures - This limits the test output to only failures.
Use --no-watchman - This is a common failure in sandboxing.

Common Mistakes:

Running without a pattern - Runs ALL tests, very slow. Always specify a pattern.
Forgetting both www variants - Test www AND www variant false for __VARIANT__ flags.
Test skipped unexpectedly - Check for @gate pragma; see feature-flags skill.

how to use test

How to use test on Cursor

AI-first code editor with Composer

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

›Cursor installed and configured on your development machine
›Node.js version 16.0+ with npm package manager (verify with node --version)
›Active project directory or workspace where you want to add test

Execute installation command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/facebook/react --skill test

The skills CLI fetches test from GitHub repository facebook/react and configures it for Cursor.

Select Cursor when prompted

The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:

◆ Which agents do you want to install to?

│

│ ── Universal (.agents/skills) ── always included ────

│ • Amp

│ • Antigravity

│ • Cline

│ • Codex

│ ●Cursor(selected)

│ • Cursor

│ • Windsurf

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/test

Reload or restart Cursor to activate test. Access the skill through slash commands (e.g., /test) or your agent's skill management interface.

⚠

Security & Verification Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.

Use Cases▌

Task Automation & Efficiency

Automate repetitive workflows and reduce manual effort

Example

Generate reports, summarize documents, draft communications

✓

Save 3-5 hours per week on routine tasks

Knowledge Enhancement

Learn new skills, understand complex topics, get expert guidance

Example

Explain concepts, provide examples, suggest learning resources

✓

Accelerate learning and skill development by 2x

Quality Improvement

Enhance output quality through reviews, suggestions, and refinements

Example

Review drafts, suggest improvements, catch errors

✓

Improve work quality by 30-40% with less effort

Implementation Guide▌

Prerequisites

›Claude Desktop or compatible AI client with skill support
›Clear understanding of task or problem to solve
›Willingness to iterate and refine outputs

Time Estimate

15-45 minutes depending on use case complexity

Installation Steps

1.Install skill using provided installation command
2.Test with simple use case relevant to your work
3.Evaluate output quality and relevance
4.Iterate on prompts to improve results
5.Integrate into regular workflow if valuable

Common Pitfalls

⚠Expecting perfect results without iteration
⚠Not providing enough context in prompts
⚠Using skill for tasks outside its intended scope
⚠Accepting outputs without review and validation

Best Practices▌

✓ Do

+Start with clear, specific prompts
+Provide relevant context and constraints
+Review and refine all outputs before using
+Iterate to improve output quality
+Document successful prompt patterns

✗ Don't

−Don't use without understanding skill limitations
−Don't skip validation of outputs
−Don't share sensitive information in prompts
−Don't expect skill to replace human judgment

💡 Pro Tips

★Be specific about desired format and style
★Ask for multiple options to choose from
★Request explanations to understand reasoning
★Combine AI efficiency with human expertise

When to Use This▌

✓ Use When

Use when skill capabilities match your task, clear ROI on time saved, and you can validate outputs. Best for repetitive tasks, learning, and quality improvement.

✗ Avoid When

Avoid when task requires deep expertise you can't validate, involves sensitive decisions, or when learning process is more valuable than speed of completion.

Learning Path▌

1Familiarize yourself with skill capabilities and limitations
2Start with low-risk, non-critical tasks
3Progress to more complex and valuable use cases
4Build expertise through regular use and experimentation

★★★★★Hana Park· Dec 20, 2024
test has been reliable in day-to-day use. Documentation quality is above average for community skills.
★★★★★Pratham Ware· Dec 8, 2024
Registry listing for test matched our evaluation — installs cleanly and behaves as described in the markdown.
★★★★★Omar Mehta· Dec 4, 2024
Keeps context tight: test is the kind of skill you can hand to a new teammate without a long onboarding doc.
★★★★★Yash Thakker· Nov 27, 2024
test reduced setup friction for our internal harness; good balance of opinion and flexibility.
★★★★★Emma Rahman· Nov 23, 2024
test is among the better-maintained entries we tried; worth keeping pinned for repeat workflows.
★★★★★Aditi Bhatia· Nov 7, 2024
Useful defaults in test — fewer surprises than typical one-off scripts, and it plays nicely with `npx skills` flows.
★★★★★Mia Jackson· Nov 7, 2024
Solid pick for teams standardizing on skills: test is focused, and the summary matches what you get after install.
★★★★★Aanya Rahman· Oct 26, 2024
test is among the better-maintained entries we tried; worth keeping pinned for repeat workflows.
★★★★★Sophia Shah· Oct 26, 2024
We added test from the explainx registry; install was straightforward and the SKILL.md answered most questions upfront.
★★★★★Dhruvi Jain· Oct 18, 2024
I recommend test for anyone iterating fast on agent tooling; clear intent and a small, reviewable surface area.
